The Manual of Style (abbreviated as MoS or MOS) is the "style manual for all Wikipedia articles. This is the primary page for the style guidelines: it covers certain topics (e.g. punctuation) in detail and "summarizes the key points of others. The "detail pages, which are cross-referenced here and linked by this page's menu or listed at "Wikipedia:Manual of Style/Contents, provide specific guidance on those topics. If any contradiction arises, this page has precedence over all detail pages of the guideline, "style essays, and the "Simplified Manual of Style.[a]

The Manual of Style presents Wikipedia's "house style. The goal is to make using Wikipedia easier and more intuitive by promoting clarity and cohesion while helping editors write articles with consistent and precise language, layout, and formatting. "Plain English works best. Avoid "ambiguity, "jargon, and vague or unnecessarily complex wording. Any new content added to the body of this page should directly address a style issue that has occurred in a significant number of instances.

Discuss style issues on the "MOS talk page.


Article titles, headings, and sections[edit]

Article titles[edit]

A title should be a recognizable name or description of the topic that is natural, sufficiently precise, concise, and consistent with the titles of related articles. If these criteria are in conflict, they should be "balanced against one another.

For guidance on formatting titles, see "WP:Article titles § Article title format section of the policy. Note the following:

The guidance contained elsewhere in the MoS, particularly § Punctuation, applies to all parts of an article, including the title. However, particular guidance in the "WP:Article titles policy, for example on punctuation in "WP:TITLESPECIALCHARACTERS, takes precedence for formatting article titles.

Section organization[edit]

Articles are divided into "sections.

All articles begin with an introductory "lead section which concisely summarizes the article's contents. The lead appears before any section headings. New information is not always important enough for the lead; it should be placed in the most appropriate section or sections. "Infoboxes, images, and related content in the lead section must be right-aligned. "Disambiguation hatnotes are placed before the lead.

If an article has at least four section headings, a navigable "table of contents appears automatically, just after the lead.

If the topic of a section is covered in more detail in a dedicated article (see "Wikipedia:Summary style), insert {{"main|Article name}} immediately under the section heading.

As explained in more detail in "WP:Manual of Style/Layout § Standard appendices and footers, optional appendix and footer sections may appear after the body of the article, in the following order:

Section headings[edit]


Section headings follow the same formatting guidance as § Article titles.

Use equal signs around a section heading: ==Title== for a primary section; ===Title=== for a subsection; and so on to =====Title=====. (=Title= is never used.[e]) The heading must be on its own line, with one blank line just before it; a blank line just after is optional and ignored (but do not use two blank lines, before or after, because that will add unwanted visible space). Spaces around the Title (e.g. == Title ==) are optional and ignored.

In addition:

An invisible comment on the same line as the heading should be inside the == == markup:[f]

Before changing a section heading, consider whether you might be breaking existing links to that section. If there are many "links to the old section title, create an "anchor with that title to ensure that the links still work. Similarly, when linking to a section of an article, leave an invisible comment, at the heading of the target section, naming the linking articles so that if the section title is altered the linking articles can be fixed. For example:

==Implications<!--Section linked from [[Richard Dawkins]], [[Daniel Dennett]] (see [[MOS:HEAD]])-->==

Heading-like material:

Several of those provisions are also applicable to content that serves the same basic function as a heading. For example, "headers of tables (and of table columns and rows) should follow the advice about sentence case, redundancy, images, and questions. However, table headings can incorporate citations and may begin with, or be, numbers. Unlike page headings, table headers do not automatically generate link anchors. Aside from sentence case in glossaries, the heading advice also applies to the term entries in "description lists. If using "template-structured glossaries, terms will automatically have link anchors, but will not otherwise. Citations for description-list content go in the term or definition element, as needed.

Retaining existing styles[edit]


On some questions of style, the MoS provides more than one acceptable answer; on other questions it gives no guidance. The "Arbitration Committee has expressed the principle that "When either of two styles are acceptable it is inappropriate for a Wikipedia editor to change from one style to another unless there is some substantial reason for the change."[1]

Edit-warring over styles is never acceptable. If the existing style of an article is problematic, discuss it at the article's talk page or if necessary at the "MoS talk page.

National varieties of English[edit]


The English Wikipedia prefers no major national variety of the language over any other. These varieties (for example "American English or "British English) differ in a number of ways, including vocabulary (elevator vs. lift), spelling (center vs. centre), date formatting ("April 13" vs. "13 April"), and occasionally grammar (see § Plurals). The following subsections describe how to determine the appropriate variety for an article. (The accepted style of punctuation is covered in § Punctuation.)

Articles such as "English plurals and "Comparison of American and British English provide information on the differences between these major varieties of the language.

Opportunities for commonality[edit]


Prefer vocabulary common to all varieties of English. Insisting on a single term or a single usage as the only correct option does not serve the purposes of an international encyclopedia.

Consistency within articles[edit]


While Wikipedia does not prefer any national variety of English, within a given article the conventions of one particular variety should be followed consistently. The exceptions are:

Strong national ties to a topic[edit]


An article on a topic that has strong ties to a particular English-speaking nation should use the (formal, not colloquial) English of that nation. For example:

In an article about a modern writer, it is often a good choice to use the variety of English in which the subject wrote, especially if the writings are quoted. For example, the article "J. R. R. Tolkien follows his use of British English with "Oxford spelling. In an article about a supranational or international organization, it is often a good choice to use the variety of English used by that body.

This guideline should not be used to claim national ownership of any article; see "Wikipedia:Ownership of articles.

Retaining the existing variety[edit]


When an English variety's consistent usage has been established in an article, maintain it in the absence of consensus to the contrary. With few exceptions (e.g., when a topic has strong national ties or a term/spelling carries less ambiguity), there is no valid reason for such a change.

When no English variety has been established and discussion does not resolve the issue, use the variety found in the first post-"stub revision that introduced an identifiable variety. The established variety in a given article can be documented by placing the appropriate "Varieties of English template on its talk page.

An article should not be edited or renamed simply to switch from one variety of English to another. The {{"subst:"uw-lang}} template may be placed on an editor's talk page to explain this.

Capital letters[edit]

Wikipedia article titles and section headings use sentence case, not title case; see "WP:Article titles and § Section headings. For capitalization of list items, see § Bulleted and numbered lists. Other points concerning capitalization are summarized below; full information can be found at "WP:Manual of Style/Capital letters.

Capitalization of "The"[edit]

Generally, do not capitalize the in mid-sentence: throughout the United Kingdom, not throughout The United Kingdom. Conventional exceptions include certain proper names (he visited The Hague) and most titles of creative works (Tolkien wrote The Lord of the Rings—but be aware that the may not be part of the title itself e.g. Homer wrote the Odyssey).

For the in band names, see "WP:Manual of Style/Music § Names (definite article).

Titles of works[edit]

The English-language titles of compositions (books and other print works, songs and other audio works, films and other visual media works, paintings and other artworks, etc.) are given in "title case, in which every word is given an initial capital except for certain less important words (as detailed at "WP:Manual of Style/Capital letters § Composition titles). The first and last words in an English-language title are always capitalized.

Capitalization in foreign-language titles varies, even over time within the same language; generally, retain the style of the original for modern works, and follow the usage in English-language reliable sources for historical works. Many of these items should also be in italics, or enclosed in quotation marks.

Titles of people[edit]

Religions, deities, philosophies, doctrines[edit]

Calendar items[edit]

Animals, plants, and other organisms[edit]


When using "taxonomic ("scientific") names, capitalize and italicize the genus: Berberis, Erithacus. (Supergenus and subgenus, when applicable, are treated the same way.) Italicize but do not capitalize taxonomic ranks at the level of species and below: Berberis darwinii, Erithacus rubecula superbus, Acacia coriacea subsp. sericophylla; no exception is made for proper names forming part of scientific names. Higher taxa (order, family, etc.) are capitalized in Latin (Carnivora, Felidae) but not in their English equivalents (carnivorans, felids); they are not italicized in either form.

"Cultivar and "cultivar group names of plants are not italicized, and are capitalized (including the word "Group" in the name); cultivar names appear within single quotes (Malus domestica 'Red Delicious'), while cultivar groups do not (Cynara cardunculus Scolymus Group).

English "vernacular ("common") names are given in lower case in article prose (plains zebra, mountain maple, and southwestern red-tailed hawk) and in sentence case at the start of sentences or other places where the first letter of the first word is capitalized.[b] They are additionally capitalized where they contain proper names: Przewalski's horse, California condor, and fair-maid-of-France. This applies to species and subspecies, as in the previous examples, as well as general names for groups or types of organisms: bird of prey, oak, great apes, Bryde's whales, mountain dog, poodle, Van cat, wolfdog. When the common name coincides with a scientific taxon, do not capitalize or italicize, except where addressing the organism taxonomically: A lynx is any of the four species within the Lynx genus of medium-sized wild cats. Non-English vernacular names, when relevant to include, are handled like any other foreign-language terms: italicized as such, and capitalized only if the rules of the native language require it. Non-English names that have become English-assimilated common names are treated as English (ayahuasca, okapi).

Create "redirects from alternative capitalization and spelling forms of article titles, and from alternative names, e.g., "Adélie Penguin, "Adelie penguin, "Adelie Penguin and "Pygoscelis adeliae should all redirect to "Adélie penguin.

Celestial bodies[edit]

Compass points[edit]

Do not capitalize directions such as north, nor their related forms (We took the northern road), except where they are parts of proper names (Great North Road, Great Western Drive, South Pole).

Capitalize names of regions if they have attained proper-name status, including informal conventional names (Southern California; the Western Desert), and derived terms for people (e.g., a Southerner as someone from the "Southern United States). Do not capitalize descriptive names for regions that have not attained the status of proper names, such as southern Poland.

Composite directions may or may not be hyphenated, depending on the variety of English adopted in the article. Southeast Asia and northwest are more common in American English; but South-East Asia and north-west in British English. In cases such as north–south dialogue and east–west orientation, use an en dash; see § En dashes: other uses.

Proper names versus generic terms[edit]

Capitalize names of particular institutions (the founding of the University of Delhi;  the history of Stanford University) but not generic words for institutions (the high school is near the university). Do not capitalize the at the start of an institution's name, regardless of the institution's preferred style.

Treat political or geographic units similarly: The city has a population of 55,000;  The two towns merged to become the City of Smithville. Do not mimic the style of local newspapers which refer to their municipality as "the City" or "The City"; an exception is the "City of London, referred to as the City.



"Ligatures should be used in languages in which they are standard (hence Moreau's last words were clin d'œil is preferable to Moreau's last words were clin d'oeil) but not in English (encyclopedia or encyclopaedia, not encyclopædia), except in proper names (Æthelstan not Aethelstan).


Abbreviations are shortened forms of words or phrases. In strict analysis, they are distinct from "contractions, which use an "apostrophe (e.g., won't, see § Contractions) and "initialisms. An initialism is formed from some or all of the initial letters of words in a phrase. In some linguistic works, acronyms are initialisms pronounced as words (e.g. "NATO), distinct from initialisms pronounced as individual letters (e.g. "US). Herein, the term acronym is collectively used to mean initialism. General statements regarding abbreviations are inclusive of acronyms.

Write out both the full version and the abbreviation at first occurrence[edit]

When an abbreviation is used in an article, give the expression in full at first, followed by the abbreviation in parentheses (round brackets). Thereafter the abbreviation can be used alone:

The New Democratic Party (NDP) won the 1990 Ontario election with a significant majority ... The NDP quickly became unpopular with voters.

If the full version is already in parentheses, use a comma and or to indicate the abbreviation:

They first debated the issue in 1992 (at a convention of the New Democratic Party, or NDP)

An exception is made for very common abbreviations; in most articles they require no expansion: (PhD, DNA, USSR).

Do not apply title case in a full version simply because capitals are used in the abbreviation:

Correct (not a proper name): We used digital scanning (DS) technology
Incorrect: We used Digital Scanning (DS) technology
Correct (a proper name): The film was produced by the British Broadcasting Corporation (BBC)

Plural and possessive forms[edit]

Like other nouns, "acronyms are pluralized via addition of -s or -es: They produced three CD-ROMs;  three different BIOSes were released. As always, do not use an apostrophe to form a plural: One DVD's menu was wrong, and five CD-ROMs' titles were misspelled, not He bought two DVD's.

Full stops and spaces[edit]

Abbreviations may or may not be closed with a full stop or point (period – .). A consistent style should be maintained within an article. North American usage is typically to end all abbreviations with a period (Dr. Smith of 42 Drummond St.), but in common British and Australian usage, no stop is used if the abbreviation ends in the last letter of the unabbreviated form, except when confusion could result (Dr Smith of 42 Drummond St). This is also common practice in scientific writing. Regardless of punctuation, words that are abbreviated to more than one letter are spaced (op. cit. not op.cit. or opcit). There are some exceptions: PhD (see above) for "Philosophiae Doctor"; BVetMed for "Bachelor of Veterinary Medicine".

US and U.S.[edit]


US is a commonly used abbreviation for United States, although U.S. – with periods and without a space – remains common in North American publications, including in news journalism.[h] Multiple American style guides, including "The Chicago Manual of Style (since 2010), now deprecate "U.S." and recommend "US".

For commonality reasons, use US by default when abbreviating, but retain U.S. in American or Canadian English articles in which it is already established, unless there is a good reason to change it. Because use of periods for abbreviations and acronyms should be consistent within any given article, use US in an article with other country abbreviations, and especially avoid constructions like the U.S. and the UK. In longer abbreviations that incorporate the country's initials (USN, USAF), never use periods. When the United States is mentioned with one or more other countries in the same sentence, US (or U.S.) may be too informal, especially at the first mention or as a noun instead of an adjective (France and the United States, not France and the US). Do not use the spaced U. S. or the archaic U.S. of A., except when quoting. Do not use U.S.A. or USA except in a quotation, as part of a proper name (Team USA), or in certain technical and formal uses (e.g., the "ISO 3166-1 alpha-3, "FIFA, and "IOC country codes).


To indicate approximately, the abbreviation c. (followed by a space and not italicized) is preferred over circa, ca., or approx. The template {{"circa}} may be used.

Do not use unwarranted abbreviations[edit]

Avoid abbreviations when they might confuse the reader, interrupt the flow, or appear informal. For example, do not use approx. for approximate or approximately, except in a technical passage where the term occurs many times or in an infobox or a data table to reduce width.

Do not invent abbreviations or acronyms[edit]

Generally avoid devising new abbreviations, especially acronyms (World Union of Billiards is good as a translation of Union Mondiale de Billard, but neither it nor the reduction WUB is used by the organization; so use the original name and its official abbreviation, UMB).

If it is necessary to abbreviate in a tight space, such as a "column header in a table, use widely recognized abbreviations. For example, for New Zealand gross national product, use NZ and GNP, with a link if the term has not already been written out in the article: NZ "GNP. Do not make up initialisms such as NZGNP.

HTML elements[edit]

Either the <abbr> element or the {{"abbr}} template can be used for abbreviations and acronyms: <abbr title="World Health Organization">WHO</abbr> or {{"abbr|WHO|World Health Organization}} will generate WHO; "hovering over the rendered text causes a "tooltip of the long form to pop up. "MediaWiki, the software on which Wikipedia runs, does not support <acronym>.



In normal text and headings, use and instead of the "ampersand (&): January 1 and 2, not January 1 & 2. But retain an ampersand when it is a legitimate part of a proper noun, such as in "Up & Down or "AT&T. Elsewhere, ampersands may be used with consistency and discretion where space is extremely limited (e.g. tables and infoboxes). Quotations (see also "MOS:QUOTE) may be cautiously modified, especially for consistency where different editions are quoted, as modern editions of old texts routinely replace ampersands with and (just as they replace other disused "glyphs, "ligatures, and abbreviations).




Boldface or CAPITALS are not normally used for emphasis; use italics instead, but sparingly: overuse of emphasis reduces its effectiveness. Ideally, use <em>word</em> or {{em|word}} instead of ''word'' to indicate emphasis: The vaccine is {{em|not}} a cure, but a prophylactic. This allows "user style sheets to handle emphasis in a customized way, and is an aid to re-users and translators.[2]


Use italics for the titles of works such as books, pamphlets, films (including short films), television series, named exhibitions, computer and video games (but not other software), music albums, and paintings. The titles of articles, chapters, songs, television episodes, research papers and other short works take double quotation marks instead. Italics are not used for major revered religious works (the Bible, the Quran, the Talmud). Many of these titles should also be in title case.

Words as words[edit]

Use italics when mentioning a word or character (see "Use–mention distinction) or a string of words up to one full sentence (the term panning is derived from panorama; the most common letter in English is e). When a whole sentence is mentioned, quotation marks may be used instead, with consistency (The preposition in She sat on the chair is on; or The preposition in "She sat on the chair" is "on"). Quotation marks may also be used for this purpose for shorter material to avoid confusion, such as when italics are already being heavily used in the page for some other purpose (e.g. many non-English words and phrases). Mentioning (to discuss grammar, wording, punctuation, etc.) is different from quoting (in which something is usually expressed on behalf of a quoted source).

A closely related use of italics is when introducing or distinguishing terms: The natural numbers are the integers greater than 0.

Foreign words[edit]

Use italics for phrases in other languages and for isolated foreign words that are not common in everyday English. However, proper names (such as place names) in other languages are not usually italicized, nor are terms in non-Latin scripts.

Scientific names[edit]

Use italics for the scientific names of plants, animals, and other organisms at the genus level and below (italicize Panthera leo but not Felidae). The hybrid sign is not italicized (Rosa × damascena), nor is the "connecting term" required in three-part botanical names (Rosa gallica subsp. officinalis).

Quotations in italics[edit]


Don't use italics for quotations. Instead, use quotation marks for short quotations and block quoting for long ones.

Italics within quotations[edit]

Use italics within quotations if they are already in the source material. When adding emphasis on Wikipedia, add an editorial note [emphasis added] after the quotation.

If the source has used italics (or some other styling) for emphasis and this is not otherwise evident, the editorial note [emphasis in original] should appear after the quotation.

Effect on nearby punctuation[edit]


Italicize only the elements of the sentence affected by the emphasis. Do not italicize surrounding punctuation.

Italicized links[edit]

For a link to function, any italics markup must be either completely outside the link markup, or in the "link's "piped" portion.

Controlling line breaks[edit]


It is sometimes desirable to force a text segment to appear entirely on a single line‍—‌that is, to prevent a line break (line wrap) from occurring anywhere within it.

It is desirable to prevent line breaks where breaking across lines might be confusing or awkward. For example:

Whether a non-breaking space is appropriate depends on context: whereas it is appropriate to use 12{{"nbsp}}MB in prose, it may be counterproductive in a table (where horizontal space is precious) and unnecessary in a short parameter value in an infobox (where a break would never occur anyway).

A line break may occur at a thin space (&thinsp;, or {{"thinsp}}), which is sometimes used to correct too-close placement of adjacent characters. To prevent this, consider using {{"nobr}}.

Insert non-breaking and thin spaces symbolically ({{nbsp}}, {{thinsp}}, &nbsp; or &thinsp;), never by entering them directly into the edit window from the keyboard – they are visually indistinguishable from regular spaces, and later editors will be unable to see what they are. Inside wikilinks, a construction such as [[World War&nbsp;II]] works as expected, but [[World War{{nbsp}}II]] will not work.

Adjacent quotation marks: The templates {{"' "}} and {{"" '}} will add a sliver of visual space between adjacent quotation marks/apostrophes for better readability.[i] Markup: He announced, "The answer was 'Yes!{{"' "}} or {{"" '}}Yes!' was the answer."



"Brief quotations of copyrighted text may be used to illustrate a point, establish context, or attribute a point of view or idea. While quotations are an indispensable part of Wikipedia, try not to overuse them. Using too many quotes is incompatible with an encyclopedic writing style and may be a "copyright infringement. It is generally recommended that content be written in Wikipedia editors' own words. Consider paraphrasing quotations into plain and concise text when appropriate (while being aware that "close paraphrasing can still violate copyright).

Original wording[edit]


Quotations must be "verifiably attributed, and the wording of the quoted text should be faithfully reproduced. This is referred to as the principle of minimal change. Where there is good reason to change the wording, enclose changes within square brackets (for example replacing pronouns with nouns that aren't indentified in the quote: "Ocyrhoe told [her father] his fate" instead of "Ocyrhoe told him his fate"). If there is a significant error in the original statement, use [["sic]] or the template {{"sic}} to show that the error was not made by Wikipedia. However, trivial spelling and typographic errors should simply be corrected without comment (for example, correct basicly to basically and harasssment to harassment), unless the slip is contextually important.

Use ellipses to indicate omissions from quoted text. Legitimate omissions include extraneous, irrelevant, or parenthetical words, and unintelligible speech (umm, and hmm). Do not omit text where doing so would remove important context or alter the meaning of the text. When a vulgarity or obscenity is quoted, it should appear exactly as it does in the cited source; Wikipedians should "never bowdlerize words by replacing letters with dashes, asterisks, or other symbols, except when faithfully reproducing quoted text that did so. In carrying over such an alteration from a quoted source, [["sic]] or the {{"sic}} template may be used to indicate that the transcription is exact.

In direct quotations, retain dialectal and archaic spellings, including capitalization (but not archaic glyphs and ligatures, as detailed below).

Point of view[edit]

Quotation should be used, with attribution, to present emotive opinions that cannot be expressed in Wikipedia's own voice, but never to present cultural norms as simply opinional:

Concise opinions that are not overly emotive can often be reported with attribution instead of direct quotation. Use of quotation marks around simple descriptive terms can often seem to imply something doubtful regarding the material being quoted; sarcasm or "weasel words, like "supposedly" or "so-called", might be inferred.

Typographic conformity[edit]


A quotation is not a facsimile and, in most cases, it is not a requirement that the original formatting be preserved. Formatting and other purely typographical elements of quoted text should be adapted to English Wikipedia's conventions without comment provided that doing so will not change or obscure meaning or intent of the text; this practice is universal among publishers. These are alterations which make no difference when the text is read aloud, such as:

However, national varieties should not be changed, as these may involve changes in vocabulary. For example, a quotation from a British source should retain British spelling, even in an article that otherwise uses American spelling. (See § Consistency within articles.)

Direct quotation should not be used in an attempt to preserve the formatting preferred by an external publisher, especially when the material would otherwise be unchanged:

Italics can be used to mark a particular usage as a "term of art (a case of ""words as words"), especially when it is unfamiliar or should not be reworded by a non-expert:

When quoting a complete sentence, it is recommended to keep the first word capitalized unless the quoted passage has been integrated into the surrounding sentence without an introduction like "X said that" or "according to X". If it has, the original capital letter may be lower-cased in square brackets: "The" → "[t]he".


The reader must be able to determine the source of any quotation, at the very least via a footnote. The source must be named in article text if the quotation is an opinion (see "Wikipedia:Neutral point of view § Attributing and specifying biased statements). When attributing a quotation, avoid "characterizing it in a biased manner.

Quotations within quotations[edit]


For quotations within quotations, use double quote marks outermost and, working inward, alternate single with double quote marks: He said, "That book claims, 'Voltaire said "I disapprove of what you say, but I will defend to the death your right to say it."'" For two or more quote marks in immediate succession, use {{"" '}}, {{"' "}}, or (as in the example just given) {{"" ' "}}, which add a small amount of nonbreaking space between the quote marks.



Be conservative when linking within quotations; link only to targets that correspond to the meaning clearly intended by the quote's author. Where possible, link from text outside of the quotation instead – either before it or soon after. (If quoting "hypertext, add an editorial note, [link in original] or [link added], as appropriate, to avoid ambiguity as to whether the link was made by the original author.)

Block quotations[edit]


Format a long quote (more than about 40 words or a few hundred characters, or consisting of more than one paragraph, regardless of length) as a "block quotation, indented on both sides. Block quotations can be enclosed in {{"quote}} or <blockquote>...</blockquote>. The template also provides parameters for attribution. Do not enclose block quotations in quotation marks (and especially avoid decorative quotation marks in normal use, such as those provided by the {{"cquote}} template). Block quotations using a colored background are also discouraged.

Poetry, lyrics, and other formatted text may be quoted inline if they are short, or presented in a block quotation. If inline, line breaks should be indicated by /, and paragraph or stanza breaks by //. Wikipedia's "MediaWiki software does not normally render line breaks or indentation inside a {{quote}} or <blockquote>, but the <poem> extension can be used to preserve them:

"'Tis some visiter," I muttered, "tapping at my chamber door—
              Only this and nothing more."

This will result in the following, indented with both the blockquote and the spaces (it may also be in a smaller or larger font, depending on the browser):

"'Tis some visiter," I muttered, "tapping at my chamber door—
              Only this and nothing more."

If the entire quotation should be wrapped in <poem> tags, the template {{"poemquote}} provides a simple means to achieve this, with the same interface as {{"quote}}.


Do not abuse block quotation markup to indent non-quotations. Various templates are available for indentation, including {{"block indent}}, and (for inline use) {{"in5}}. For more information on the accessibility problems of using : ("description list markup) for visual indentation, see "WP:Manual of Style/Accessibility § Indentation.

Foreign-language quotations[edit]

Quotations from foreign-language sources should appear with a translation into English, preferably a modern one. Quotations that are translations should be explicitly distinguished from those that are not. Indicate the original source of a translation (if it is available, and not first published within Wikipedia), and the original language (if that is not clear from the context).

If the original, untranslated text is available, provide a reference for it or include it, as appropriate.

When editors themselves translate foreign text into English, care must always be taken to include the original text, in italics (except for non-Latin-based writing systems), and to use actual and (if at all possible) common English words in the translation. Unless you are certain of your competency to translate something, see "Wikipedia:Translation for assistance.




Quotation marks[edit]


In the material below, the term quotation includes conventional uses of quotation marks such as for titles of songs, chapters, episodes, and so on.

Quotation characters

Double or single
Enclose most quotations with double quotation marks (Bob said: "Jim ate the apple."). Multiple enclosed quotations should alternate double and single quotation marks: (Bob said: "Did Jim say 'I ate the apple' after he left?").[j] Exceptions:
  • Plant cultivars take single quotation marks (Malus domestica 'Golden Delicious'; see "Wikipedia:Naming conventions (flora)).
  • "Simple glosses that translate or define unfamiliar terms usually take single quotes (Cossack comes from the Turkic qazaq, 'freebooter').
Article openings
In the bolded text typically appearing at the opening of an article:
  • Any quotation marks that are part of the title should be in bold just like the rest of the title (from ""A" Is for Alibi: "A" Is for Alibi is a mystery novel ...).
  • Quotation marks not part of the article title should not be bolded (from "Jabberwocky: "Jabberwocky" is a nonsense poem ...; from "Buffalo Bill: William Frederick "Buffalo Bill" Cody was an American scout, bison hunter, and showman ...).
Punctuation before quotations
The use of a comma before a quotation embedded within a sentence is optional, if a non-quoted but otherwise identical construction would work grammatically without the comma:
  • The report stated "There was a 45% reduction in transmission rate." (cf. the non-quotation The report stated there was a 45% reduction in transmission rate.)
  • The report stated, "There was a 45% reduction in transmission rate."
The comma-free approach is often used with partial quotations:
  • The report observed "a 45% reduction in transmission rate".
Commas are usually used with interrupted quotations:
  • "Life", Anaïs Nin wrote, "shrinks or expands in proportion to one's courage."
A comma is required when it would be present in the same construction if none of the material were a quotation:
  • In Margaret Mead's view, "we must recognize the whole gamut of human potentialities" to enrich our culture.
Do not insert a comma if it would confuse or alter the meaning:
  • Caitlyn Jenner expressed concerns about children "who are coming to terms with being true to who they are". (Accurate quote of a statement about some children – specifically those children "who are coming to terms ...")
  • Caitlyn Jenner expressed concerns about children, "who are coming to terms with being true to who they are". (Changes the meaning to imply Jenner was expressing concern about all children, while separately observing that children, in general, "are coming to terms ...")
It is clearer to use a colon to introduce a quotation if it forms a complete sentence, and this should always be done for multi-sentence quotations:
  • The report stated: "There was a 45% reduction in transmission rate."
  • Albert Einstein wrote: "Logic will get you from A to B. Imagination will take you everywhere."
No additional punctuation is necessary for an explicit words-as-words scenario:
  • The message was unintelligible except for the fragments "help soon" and "how much longer before".

Names and titles[edit]

Quotation marks should be used for the following names and titles:

For example: The song ""Lucy in the Sky with Diamonds" from the album "Sgt. Pepper's Lonely Hearts Club Band by the band "the Beatles.

Do not use quotation marks or italics for:

Many, but not all, of the above items should also be in title case.

Punctuation inside or outside[edit]


On the English Wikipedia, use the ""logical quotation" style in all articles, regardless of the variety of English in which they are written. Include terminal punctuation within the quotation marks only if it was present in the original material, and otherwise place it after the closing quotation mark. For the most part, this means treating periods and commas in the same way as question marks: Keep them inside the quotation marks if they apply only to the quoted material and outside if they apply to the whole sentence. Examples are given below.

If the quotation is a single word or a sentence fragment, place the terminal punctuation outside the closing quotation mark. When quoting a full sentence, the end of which coincides with the end of the sentence containing it, place terminal punctuation inside the closing quotation mark.

If the quoted sentence has been broken up with an editorial insertion, still include the terminal punctuation inside the closing quotation mark.

If the quoted sentence is followed by a "clause that should be preceded by a comma, omit the "full stop—but other terminal punctuation, such as a question mark or exclamation mark, may be retained. A question should always end with a question mark.

If the quoted sentence is followed by a clause identifying the speaker, use a comma outside the quotation mark instead of a full stop inside it, but retain any other terminal punctuation, such as question marks.

Do not follow quoted words or fragments with commas inside the quotation marks, except where a longer quotation has been broken up and the comma is part of the full quotation.

Brackets and parentheses[edit]


The rules in this section apply to both round brackets ( ), often called "parentheses, and square brackets [ ].

If a sentence contains a bracketed phrase, place the sentence punctuation outside the brackets (as shown here). However, where one or more sentences are wholly inside brackets, place their punctuation inside the brackets. (For examples, see § Sentences and brackets) There should be no space next to the inner side of a bracket. An opening bracket should usually be preceded by a space, for example. This may not be the case if it is preceded by an opening quotation mark, another opening bracket, or a portion of a word:

There should be a space after a closing bracket, except where a punctuation mark follows (though a spaced dash would still be spaced after a closing bracket) and in unusual cases similar to those listed for opening brackets.

If sets of brackets are nested, use different types for adjacent levels of nesting; for two levels, it is customary to have square brackets appear within round brackets. This is often a sign of excessively convoluted expressions; it is often better to recast, linking the thoughts with commas, semicolons, colons, or dashes.

Avoid adjacent sets of brackets. Either put the parenthetic phrases in one set separated by commas, or rewrite the sentence:

Avoid: Nikifor Grigoriev (c. 1885–1919) (also known as Matviy Hryhoriyiv) was a Ukrainian insurgent leader.
Better: Nikifor Grigoriev (c. 1885–1919, also known as Matviy Hryhoriyiv) was a Ukrainian insurgent leader.
Better: Nikifor Grigoriev (c. 1885–1919) was a Ukrainian insurgent leader. He was also known as Matviy Hryhoriyiv.

Square brackets are used to indicate editorial replacements and insertions within quotations, though this should never alter the intended meaning. They serve three main purposes:

Sentences and brackets[edit]

Brackets and linking[edit]

Brackets inside of links must be "escaped:

He said, "[[John Doe|John &#91;Doe&#93;]] answered."

He said, ""John [Doe] answered."

He said, "[[John Doe|John {{bracket|Doe}}]] answered."

He said, ""John [Doe] answered."

[http://example.site On the first day &#91;etc.&#93;]

On the first day [etc.]

[http://example.site On the first day {{bracket|etc.}}]

On the first day [etc.]

The <"nowiki> markup can also be used: <nowiki>[Doe]</nowiki> or <nowiki>[etc.]</nowiki>.

If a URL itself contains square brackets, the wiki-text should use the "URL-encoded form http://example.site/foo.php?query=%5Bxxx%5Dyyy, rather than ...query=[xxx]yyy. This will avoid truncation of the link after xxx.



To indicate an omission of material from quoted text, use an "ellipsis (plural ellipses): a set of three unspaced dots: ... (The pre-composed ellipsis character (), or three dots separated by spaces (. . .), are not recommended.)

Pause or suspension of speech
Three dots are occasionally used to represent a pause in or suspense of speech, in which case the punctuation is retained in its original form: Virginia's startled reply was "Could he ...? No, I cannot believe it!". Avoid this usage except in direct quotations. When it indicates an incomplete word, no space is used between the word fragment(s) and the ellipsis: The garbled transmission ended with "We are stranded near San L...o", interpreted as a reference to either San Leandro or San Lorenzo.
With square brackets
An ellipsis does not normally need square brackets around it, because its function is usually obvious. However, square brackets may optionally be used for precision, to make it clear that the ellipsis is not itself quoted; this is usually only necessary if the quoted passage also uses three periods in it to indicate a pause or suspension. The ellipsis should follow exactly the principles given above but with square brackets inserted immediately before and after it (Her long rant continued: "How do I feel? How do you think I ... look, this has gone far enough! [...] I want to go home!").



"Commas are the most frequently used punctuation marks and can be the most difficult to use well. Some important points regarding their use follow below and at § Semicolons.

Serial commas[edit]


A "serial comma (also known as an Oxford comma or a Harvard comma) is a comma used immediately before a conjunction (and, or, nor) in a list of three or more items: the phrase ham, chips, and eggs includes a serial comma, while ham, chips and eggs omits it. Editors may use either convention so long as each article is internally consistent; however, there are cases in which either omitting or including the serial comma results in ambiguity:

The author thanked her friends, Sinéad O'Connor and Bob Marley – which may list either four or more people (the friends and the two people named) or two people (O'Connor and Marley, who are the friends).
The author thanked a friend, Sinéad O'Connor, and Bob Marley – which may list either two people (O'Connor, who is the friend, and Marley) or three people (the first being the friend, the second O'Connor, and the third Marley).

In such cases of ambiguity, clarify one of three ways:



A "colon (:) introduces something which demonstrates, explains, or modifies what has come before, or is a list of items that has just been introduced. The items in such a list may be separated by commas; or, if they are more complex and perhaps themselves contain commas, the items should be separated by semicolons:

We visited several tourist attractions: the Leaning Tower of Pisa, which I thought could fall at any moment; the Bridge of Sighs; the supposed birthplace of Petrarch, or at least the first known house in which he lived; and so many more.

A colon may also be used to introduce "direct speech enclosed within quotation marks (see § Quotation marks).

In most cases a colon works best with a complete grammatical sentence before it. There are exceptional cases, such as those where the colon introduces items set off in new lines like the very next colon here. Examples:

Correct: He attempted it in two years: 1941 and 1943.
Incorrect: The years he attempted it included: 1941 and 1943. (Just remove the colon.)
Permissible but awkward: Spanish, Portuguese, French: these, with a few others, are the West Romance languages.

Sometimes the word following a colon is capitalized, if that word effectively begins a new grammatical sentence, and especially if the colon serves to introduce more than one sentence:

No sentence should contain more than one colon. There should never be a hyphen or a dash immediately following a colon. No space precedes a colon, and a space must follow one.[n]



A "semicolon (;) is sometimes an alternative to a full stop (period), enabling related material to be kept in the same sentence; it marks a more decisive division in a sentence than a comma. If the semicolon separates clauses, normally each clause must be independent (meaning that it could stand on its own as a sentence); in many cases, only a comma or only a semicolon will be correct in a given sentence.

Correct: Though he had been here before, I did not recognize him.
Incorrect:    Though he had been here before; I did not recognize him.

Above, "Though he had been here before" cannot stand on its own as a sentence, and therefore is not an independent clause.

Correct: Oranges are an acid fruit; bananas are classified as alkaline.
Incorrect: Oranges are an acid fruit, bananas are classified as alkaline.

This incorrect use of a comma between two independent clauses is known as a "comma splice; however, in certain kinds of cases, a comma may be used where a semicolon would seem to be called for:

Accepted: "Life is short, art is long." (two brief clauses in an "aphorism; see "Ars longa, vita brevis)
Accepted: "I have studied it, you have not." (reporting brisk conversation, like this reply of "Newton's)

A sentence may contain several semicolons, especially when the clauses are parallel in construction and meaning; multiple unrelated semicolons are often signs that the sentence should be divided into shorter sentences, or otherwise refashioned.

Unwieldy: Oranges are an acid fruit; bananas are classified as alkaline; pears are close to neutral; these distinctions are rarely discussed.
One better way: Oranges are an acid fruit, bananas are alkaline, and pears are close to neutral; these distinctions are rarely discussed.

Semicolons are used in addition to commas to separate items in a listing, when commas alone would result in confusion.

Confusing: Sales offices are located in Boston, Massachusetts, San Francisco, California, Singapore, and Millbank, London, England.
Clear: Sales offices are located in Boston, Massachusetts; San Francisco, California; Singapore; and Millbank, London, England.

Semicolon before "however"[edit]


The meaning of a sentence containing a trailing clause that starts with the word "however" depends on the punctuation preceding that word. A common error is to use the wrong punctuation, thereby changing the meaning to one not intended.

When the word "however" is an adverb meaning "nevertheless", it should be preceded by a semicolon and followed by a comma. Example:

It was obvious they could not convert these people; however, they tried.
Meaning: It was obvious they could not convert these people; nevertheless, they tried.

When the word "however" is a conjunction meaning "in whatever manner", or "regardless of how", it may be preceded by a comma but not by a semicolon, and should not be followed by punctuation. Example:

It was obvious they could not convert these people, however they tried.
Meaning: It was obvious they could not convert these people, regardless of how they tried.

In the first case, the clause that starts with "however" cannot be swapped with the first clause; in the second case this can be done without change of meaning:

However they tried, it was obvious they could not convert these people.
Meaning: Regardless of how they tried, it was obvious they could not convert these people.

If the two clauses cannot be swapped, a semicolon is required.

A sentence or clause can also contain the word "however" in the middle, if it is an adverb meaning "although", which could have been placed at the beginning but does not start a new clause in mid-sentence. In this use, the word may be enclosed between commas. Example:

He did not know, however, that the venue had been changed at the last minute.
Meaning: However, he did not know that the venue had been changed at the last minute.



"Hyphens (-) indicate conjunction. There are three main uses:

  1. In hyphenated personal names: John Lennard-Jones.
  2. To link "prefixes with their main terms in certain constructions (quasi-scientific, pseudo-Apollodorus, ultra-nationalistic).
    • A hyphen may be used to distinguish between "homographs (re-dress means dress again, but redress means remedy or set right).
    • There is a clear trend to join both elements in all varieties of English (subsection, nonlinear), particularly in American English. British English tends to hyphenate when the letters brought into contact are the same (non-negotiable, sub-basement) or are vowels (pre-industrial), or where a word is uncommon (co-proposed, re-target) or may be misread (sub-era, not subera). American English reflects the same factors, but is more likely to close up without a hyphen. Consult "a good dictionary, and see § National varieties of English.
  3. To link related terms in "compound modifiers:[o]
    • Hyphens can help with ease of reading (face-to-face discussion, hard-boiled egg) and are particularly useful in long noun phrases: gas-phase reaction dynamics. But never insert a hyphen into a proper name (Middle Eastern cuisine, not Middle-Eastern cuisine).
    • A hyphen can help to disambiguate (little-celebrated paintings is not a reference to little paintings; a government-monitoring program is a program that monitors the government, whereas a government monitoring program is a government program that monitors something else).
    • Many compounds that are hyphenated when used "attributively (adjectives before the nouns they qualify: a light-blue handbag, a 34-year-old woman) or "substantively (as a noun: she is a 34-year-old), are usually not hyphenated when used "predicatively (descriptive phrase separated from the noun: the handbag was light blue, the woman is 34 years old). Where there would otherwise be a loss of clarity, a hyphen may optionally be used in the predicative form as well (hand-fed turkeys, the turkeys were hand-fed). Awkward attributive hyphenation can sometimes be avoided with a simple rewording: Hawaiian-native culturenative Hawaiian culture.
    • Avoid using a hyphen after a standard -ly adverb (a newly available home, a wholly owned subsidiary) unless part of a larger compound (a slowly-but-surely strategy). In rare cases, a hyphen can improve clarity if a rewritten alternative is awkward, but rewording is usually preferable: The idea was clearly stated enough can be disambiguated as The idea clearly was stated often enough or The idea was stated with enough clarity.
    • A few words ending in -ly function as both adjectives and adverbs (a kindly-looking teacher; a kindly provided facility). Some such dual-purpose words (like early, only, northerly) are not standard -ly adverbs, because they are not formed by addition of -ly to an independent current-English adjective. These need careful treatment: Early flowering plants appeared around 130 million years ago, but Early-flowering plants risk damage from winter frosts; only child actors (no adult actors) but only-child actors (actors without siblings).
    • A hyphen is normally used when the adverb well precedes a participle used attributively (a well-meaning gesture; but normally a very well managed firm, because well itself is modified) and even predicatively, if well is necessary to, or alters, the sense of the adjective rather than simply intensifying it (the gesture was well-meaning, the child was well-behaved, but the floor was well polished).
    • In some cases, like diode–transistor logic, the independent status of the linked elements requires an en dash instead of a hyphen. See "En dashes § Notes.
    • Use a hanging hyphen when two compound modifiers are separated (two- and three-digit numbers; a ten-car or -truck convoy; sloping right- or leftward).
    • Values and units used as compound modifiers are hyphenated only where the unit is given as a whole word; when using the unit symbol, separate it from the number with a non-breaking space (&nbsp;).
Incorrect: 9-mm gap
Correct: 9 mm gap (markup: 9&nbsp;mm gap)
Incorrect:    9 millimetre gap
Correct: 9-millimetre gap
Correct: 12-hour shift
Correct: 12 h shift

Multi-hyphenated items: It is often possible to avoid multi-word hyphenated modifiers by rewording (a four-CD soundtrack album may be easier to read as a soundtrack album of four CDs). This is particularly important where converted units are involved (the 6-hectare-limit (14.8-acre-limit) rule might be possible as the rule imposing a limit of 6 hectares (14.8 acres), and the ungainly 4.9-mile (7.9 km) -long tributary as simply 4.9-mile (7.9 km) tributary).

For optional hyphenation of compound points of the compass such as southwest/south-west, see § Compass points.

Do not use a capital letter after a hyphen except for a proper name: Graeco-Roman and Mediterranean-style, but not Gandhi-Like. In titles of published works, follow the capitalization rule for each part independently (resulting in, e.g., The Out-of-Towners), unless reliable sources consistently do otherwise in a particular case (The History of Middle-earth).

Hyphenation rules in other languages may be different. Thus, in French a place name such as Trois-Rivières ("Three Rivers") is hyphenated, when it would not be in English. Follow reliable sources in such cases.

Spacing: A hyphen is never followed or preceded by a space, except when hanging (see above) or when used to display parts of words independently, such as the prefix sub- and the suffix ‑less.

Image filenames and redirects: Image filenames are not part of the encyclopedic content; they are tools. They are most useful if they can be readily typed, so they always use hyphens instead of dashes. Similarly, article titles with dashes should also have a corresponding redirect from a copy of the title with hyphens: for example, "Michelson-Morley experiment redirects to "Michelson–Morley experiment.

Non-breaking: A non-breaking hyphen (&#8209; or {{"nbhyph}}) will not be used as a point of line-wrap.


Soft hyphens: Use "soft hyphens to mark locations where a word will be broken and hyphenated if necessary at the end of a line of text, usually in "very long words or narrow spaces (such as captions, narrow table columns, or text adjacent to a very wide image), for example: {{shy| Penn|syl|va|nia and Mass|a|chu|setts style themselves com|mon|wealths.}}. Use sparingly to avoid making wikitext difficult to read and edit.

Encoding: The hyphen is represented by the ASCII/UNICODE "HYPHEN-MINUS character, which is entered by the hyphen or minus key on all standard computer keyboards. Do not use the "UNICODE HYPHEN character.

Hyphenation involves many subtleties that cannot be covered here; the rules and examples presented above illustrate the broad principles.



Two forms of dash are used on Wikipedia: "en dash () and "em dash (). To enter them, click on them to the right of the "Insert" dropdown beneath the edit window, or enter them manually as &ndash; or &mdash;, respectively. Do not use a double hyphen (--) to stand in for a dash.

Sources use dashes in varying ways. For consistency and clarity, Wikipedia adopts the following principles.

In article titles[edit]

In "article titles, do not use a hyphen (-) as a substitute for an en dash, for example in "eye–hand span (since eye does not modify hand). Nonetheless, to aid searching and linking, provide a redirect with hyphens replacing the en dash(es), as in "eye-hand span. Similarly, provide "category redirects for categories containing dashes.

Punctuating a sentence (em or en dashes)[edit]

Dashes are often used to mark divisions within a sentence: in pairs (parenthetical dashes, instead of parentheses or pairs of commas); or singly (perhaps instead of a colon). They may also indicate an abrupt stop or interruption, in reporting quoted speech. In all these cases, use either unspaced em dashes or spaced en dashes, with consistency in any one article:

Dashes can clarify the sentence structure when there are already commas or parentheses, or both.

Use dashes sparingly. More than two in a single sentence makes the structure unclear; it takes time for the reader to see which dashes, if any, form a pair.

Other uses (en dash only)[edit]

The "en dash (–) has other roles, beyond its use as a sentence-punctuating dash (see immediately above). It is often analogous to the hyphen (see § Hyphens), which joins components more strongly than the en dash; or to the slash (see § Slashes), which separates alternatives more definitely. Consider the exact meaning when choosing which to use.

In ranges that might otherwise be expressed with to or through[edit]

Do not change hyphens to dashes in filenames, "URLs or templates like {{"Bibleverse}}, which formats verse ranges into URLs.

Do not mix en dashes with between or from.

If negative values are involved, an en dash might be confusing. Use words instead.

The en dash in a range is always unspaced, except when either or both elements of the range include at least one space.

In compounds when the connection might otherwise be expressed with to, versus, and, or between[edit]

Here, the relationship is thought of as parallel, symmetric, equal, oppositional, or at least involving separate or independent elements. The components may be nouns, adjectives, verbs, or any other independent part of speech. Often if the components are reversed there would be little change of meaning.

Generally, use a hyphen in compounded proper names of single entities.

An en dash between separate nations; for people and things identifying with multiple nationalities, use a hyphen when applied as an adjective or a space as a noun.

A slash or some other alternative may occasionally be better to express a ratio, especially in technical contexts (see § Slashes).

Use an en dash for the names of two or more entities in an attributive compound.

Do not use an en dash for hyphenated personal names, even when they are used as adjectives:

Do not use spaces around en dash in any of the compounds above.

Instead of a hyphen, when applying a prefix to a compound that includes a space[edit]

Use this punctuation when there are compelling grounds for retaining the construction. For example, from a speech that is simply transcribed and cannot be re-worded; or in a heading where it has been judged most natural as a common name. Otherwise recasting is better.

The en dash in all of the compounds above is unspaced.

To separate parts of an item in a list[edit]

Spaced en dashes are sometimes used between parts of list items. Below are two examples.

Other dashes[edit]

Do not use substitutes for em or en dashes, such as the combination of two hyphens (--). These were "typewriter approximations.

For a negative sign or subtraction operator, use a minus sign: , U+2212 MINUS SIGN (HTML &#8722; · &minus;). Input by clicking on it in the insert box beneath the edit window or by typing &minus;.



Generally, avoid joining two words with a "slash, also called a forward slash or solidus ( / ), because it suggests that the words are related without specifying how. Replace with clearer wording.

An example: The parent/instructor must be present at all times. Must both be present? (Then write the parent and the instructor.) Must at least one be present? (Then write the parent or the instructor.) Are they the same person? (Use a hyphen: the parent-instructor.)

In circumstances involving a distinction or disjunction, the en dash (see above) is usually preferable to the slash: the digital–analog distinction.

An unspaced slash may be used:

A spaced slash may be used:

To avoid awkward linebreaks, code spaced slashes (and fraction slashes) with a non-breaking space on the left and a normal space on the right, as in: My mama told me&nbsp;/ You better shop around. For short constructions, both spaces should be non-breaking: x&nbsp;/&nbsp;y.

Do not use the "backslash character ( \ ) in place of a slash.

Prefer the division operator ( ÷ ) to slash or fraction slash when representing elementary arithmetic in general text: 10 ÷ 2 = 5. In more advanced mathematical formulas, a "vinculum or slash is preferred: or xn/n!. (See "WP:Manual of Style/Dates and numbers § Common mathematical symbols and "Help:Displaying a formula.)



Avoid writing and/or unless ambiguity would result, or unless other constructions would be too lengthy or awkward. Instead of Most suffered trauma and/or smoke inhalation, write simply trauma or smoke inhalation (which would normally be interpreted to imply or both); or, for emphasis or precision, write trauma or smoke inhalation or both. Where more than two possibilities are present, instead of x, y, and/or z write one or more of x, y, and z or some or all of x, y, and z.

Number sign[edit]


Avoid using the "# symbol (known as the "number sign, hash sign, or pound sign) when referring to numbers or rankings. Instead write "number", "No." or "Nos."; do not use the symbol . For example:

Incorrect: Her album reached #1 in the UK album charts.
Correct: Her album reached number one in the UK album charts.
Correct: Her album reached No. 1 in the UK album charts.
Correct: Her albums Foo and Bar reached Nos. 1 and 3 respectively.

An exception is issue numbers of comic books, which unlike for other periodicals are given in general text in the form #1, unless a volume is also given, in which case write volume two, number seven or Vol. 2, No. 7. When using the abbreviations, write {{abbr|Vol.|Volume}}, {{abbr|No.|Number}}, or {{abbr|Nos.|Numbers}}.

Terminal punctuation[edit]




In normal text, never put a space before a comma, a semicolon, a colon, or a terminal punctuation mark (even in quoted material; see allowable typographical changes in § Typographic conformity).

Spaces following terminal punctuation[edit]

Software condenses two or more spaces to just one when rendering a page, so editors may use any spacing style they prefer (e.g., a single space or two spaces after a period/full stop – see "Sentence spacing). Adding or removing an "extra" space is sometimes used as a "dummy edit.

Consecutive punctuation marks[edit]


Where a word or phrase that includes terminal punctuation ends a sentence, do not add a second terminal punctuation mark. If a quoted phrase or title ends in a question mark or exclamation mark, it may confuse readers as to the nature of the article sentence containing it, and so is usually better reworded to be mid-sentence. Where such a word or phrase occurs mid-sentence, new terminal punctuation (usually a period) must be added at the end.

Incorrect: Slovak returned to the Red Hot Chili Peppers in 1985 after growing tired of What Is This?.
Acceptable: Slovak returned to the Red Hot Chili Peppers in 1985 after growing tired of What Is This?
Better: Slovak, having grown tired of What Is This?, returned to the Red Hot Chili Peppers in 1985.

Punctuation and footnotes[edit]


Ref tags (<ref>...</ref>) are used to create "footnotes (sometimes called endnotes or notes). The ref tags should immediately follow the text to which the footnote applies, with no intervening space (except possibly a "hair space, generated by {{"hsp}}). Any punctuation (see exceptions below) must precede the ref tags. Adjacent ref tags should have no space between them. This applies to all ref tags, including both "explanatory notes and "citation footnotes.

When ref tags are used, a "footnote list must be added, and is usually placed in the "Notes and References section near the end of the article in the "standard appendices and footers.

Exceptions: Ref tags are placed before dashes, not after. Where a footnote applies only to material within parentheses, the ref tags belong just before the closing parenthesis.

Punctuation after formulae[edit]

A sentence that ends with a formula should have terminal punctuation (period, exclamation mark, or question mark) after the formula. Within a sentence, place other punctuation (such as commas or colons) after the formula just as if the text were not a formula. See "WP:Manual of Style/Mathematics § Punctuation after formulae.

Dates and time[edit]

For ranges of dates and times, see § En dashes: other uses.

Dates should only be "linked when they are germane and topical to the subject, as discussed at "WP:Manual of Style/Linking § Chronological items.

Time of day[edit]

Time of day is normally expressed in figures rather than being spelled out. Use context to determine whether to use the "12- or "24-hour.


Choice of format[edit]



Years and longer periods[edit]

More information on all of the above topics can be found at "WP:Manual of Style/Dates and numbers § Dates, including the handling of dates expressed in different calendars, and times corresponding to different time zones.


The term "current" should be avoided. What is current today may not be tomorrow; situations change over time. Instead, use date- and time-specific text. To help keep information updated use the {{"as of}} template.

Incorrect: He is the current ambassador to ...
Correct: As of March 2011, he is the ambassador to ...


"WP:Manual of Style/Dates and numbers § Numbers ("MOS:NUMS) clarifies a number of situations, including the following:


Units of measurement[edit]

Common mathematical symbols[edit]


Grammar and usage[edit]



Singular nouns[edit]

Plural nouns[edit]


Official names[edit]

First-person pronouns[edit]


To maintain an objective and impersonal encyclopedic voice, an article should never refer to its editors or readers using I, my, we, us, or similar forms: We should note that some critics have argued against our proposal. But some such forms are acceptable in certain figurative uses. For example:

Second-person pronouns[edit]


Avoid addressing the reader using you or your, which sets an inappropriate tone (see also § Instructional and presumptuous language).



Use the appropriate plural; allow for cases (such as "excursus or "hanif) in which a word is now listed in major English dictionaries, and normally takes an s or es plural, not its original plural: two excursuses, not two excursus as in Latin; two hanifs, not two hanufa as in Arabic.

Some "collective nouns—such as team (and proper names of them), army, company, crowd, fleet, government, majority, mess, number, pack, and party—may refer either to a single entity or to the members that compose it. In British English, such words are sometimes treated as singular, but more often treated as plural, according to context. Exceptionally, names of towns and countries usually take singular verbs (unless they are being used to refer to a team or company by that name, or when discussing actions of that entity's government). For example, in "England are playing "Germany tonight, England refers to a "football team; but in England is the most populous country of the United Kingdom, it refers to the country. In North American English, these words (and the United States, for historical reasons) are almost invariably treated as singular; the major exception is when sports teams are referred to by nicknames that are plural nouns, when plural verbs are commonly used to match. See also § National varieties of English.

Verb tense[edit]


By default, write articles in the present tense, including those covering products or works that have been discontinued. Articles discussing works of fiction are also written in the present tense (see "Wikipedia:Writing better articles § Tense in fiction). Generally, do not use past tense except for dead subjects, past events, and subjects that no longer meaningfully exist as such.

Tense can be used to distinguish between current and former status of a subject: Dún Aonghasa is the ruin of a prehistoric Irish cliff fort. Its original shape was presumably oval or D-shaped, but parts of the cliff and fort have since collapsed into the sea. (Emphasis added for clarity.)




Avoid the use of "contractions in encyclopedic writing; e.g., instead of the informal wasn't or it's, write was not and it is. However, contractions should not be expanded mechanically; sometimes, rewriting the sentence is preferable.

Gender-neutral language[edit]


Use "gender-neutral language where this can be done with clarity and precision. For example, avoid the "generic he. This does not apply to direct quotations or the titles of works (The Ascent of Man), which should not be altered, or to wording about one-gender contexts, such as an all-female school (When any student breaks that rule, she loses privileges).

Ships may be referred to using either feminine forms ("she", "her", "hers") or neuter forms ("it", "its"). Either usage is acceptable, but each article should be internally consistent and employ one or the other exclusively. As with all optional styles, articles should not be changed from one style to another unless there is a substantial reason to do so. See "WP:Manual of Style/Military history § Pronouns.

Contested vocabulary[edit]

Avoid words and phrases that give the impression of straining for formality, that are unnecessarily regional, or that are not widely accepted. See "List of English words with disputed usage and "Wikipedia:List of commonly misused English words; see also § Identity.

Instructional and presumptuous language[edit]


Avoid such phrases as remember that and note that, which "address readers directly in an unencyclopedic tone. They are a subtle form of "Wikipedia self-reference. Similarly, phrases such as of course, naturally, obviously, clearly, and actually make presumptions about readers' knowledge, and call into question the reason for including the information in the first place. Do not tell readers that something is ironic, surprising, unexpected, amusing, coincidental, etc. Simply state the sourced facts and allow readers to draw their own conclusions. Such constructions can usually just be deleted, leaving behind proper sentences with a more academic and less pushy tone: Note that this was naturally subject to controversy in more conservative newspapers. becomes This was subject to controversy in more conservative newspapers.

Subset terms[edit]


A subset term identifies a set of members of a larger class. Common subset terms are including, among, and et cetera (etc.). Do not use redundant subset terms (so avoid constructions like: Among the most well-known members of the fraternity are included two members of the Onassis family. or The elements in stars include hydrogen, helium, etc.). Do not use including to introduce a complete list; instead use comprising, consisting of, or composed of.



When there is a discrepancy between the term most commonly used by reliable sources for a person or group and the term that person or group uses for themselves, use the term that is most commonly used by reliable sources. If it isn't clear which is most used, use the term that the person or group uses.

Disputes over how to refer to a person or group are addressed by Wikipedia "content policies, such as those on "verifiability, and "neutral point of view (and "article titles when the term appears in the title of an article).

Use specific terminology. For example, it is often more appropriate for people or things from Ethiopia (a country in Africa) to be described as Ethiopian, not carelessly (with the risk of "stereotyping) as African.

Gender identity[edit]

Main biographical article on a person whose gender might be questioned
Give precedence to self-designation as reported in the most up-to-date reliable sources, even when it doesn't match what's most common in reliable sources. When a person's gender self-designation "may come as a surprise to readers, explain it "without overemphasis on first occurrence in an article.
Any person whose gender might be questioned should be referred to by the pronouns, possessive adjectives, and gendered nouns (for example "man/woman", "waiter/waitress", "chairman/chairwoman") that reflect that person's latest expressed gender self-identification. This applies in references to any phase of that person's life, unless the subject has indicated a preference otherwise. Avoid confusing constructions (Jane Doe fathered a child) by rewriting (e.g., Jane Doe became a parent). Direct quotations may need to be handled as exceptions (in some cases adjusting the portion used may reduce apparent contradictions, and "["sic]" may be used where necessary). The MoS does not specify when and how to present former names, or whether to use the former or present name first.

See also "WP:Manual of Style/Words to watch § Neologisms and new compounds.

Referring to the person in other articles
Generally, do not go into detail over changes in name or gender presentation unless they are relevant to the passage in which the person is mentioned. Use context to determine which name or names to provide on a case-by-case basis.

Foreign terms[edit]


Foreign words should be used sparingly.

Where possible, non-English should be marked up using the appropriate "ISO language code, e.g. {{"lang|es|casa}}. There are alternatives to the {{lang}} template which also provide additional information about a foreign word or phrase, such as a link to the language name; see "Category:Multilingual support templates.

No common usage in English[edit]

Use italics for phrases in other languages and for isolated foreign words that are not current in English. See "WP:Manual of Style/Text formatting § Foreign terms for details.

Common usage in English[edit]

"Loanwords and borrowed phrases that have common usage in English—Gestapo, samurai, vice versa—do not require italics. A rule of thumb is not to italicize words that appear unitalicized in general-purpose English-language dictionaries.

Spelling and romanization[edit]


Names not originally written in one of the "Latin-script alphabets (written for example in Greek, Cyrillic, or Chinese scripts) must be given a "romanized form for use in English. Use a systematically "transliterated or otherwise romanized name (Aleksandr Tymoczko, Wang Yanhong); but if there is a common English form of the name (Tchaikovsky, Chiang Kai-shek), use that form instead.

The use of "diacritics (such as accent marks) for foreign words is neither encouraged nor discouraged; their usage depends on whether they appear in "verifiable reliable sources in English and on the constraints imposed by specialized Wikipedia guidelines (see also "WP:Manual of Style/Proper names § Diacritics). Provide "redirects from alternative forms that use or exclude diacritics.

Spell a name consistently in the title and the text of an article. See relevant policy at "WP:Article titles; see also "WP:Naming conventions (use English). For foreign names, phrases, and words generally, adopt the spellings most commonly used in English-language references for the article, unless those spellings are idiosyncratic or obsolete. If a foreign term does not appear in the article's references, adopt the spelling most commonly used in other "verifiable reliable sources (for example "other English-language dictionaries and encyclopedias). For punctuation of compounded forms, see relevant guidelines in § Punctuation.

Sometimes the usage will be influenced by other guidelines, such as § National varieties of English, which may lead to different choices in different articles.

Other concerns[edit]

Technical language[edit]


Some topics are intrinsically technical, but editors should try to make them understandable to as many readers as possible. Minimize "jargon, or at least explain it or tag it using {{"Technical}} or {{"Technical-statement}} for other editors to fix. For unavoidably technical articles, a separate introductory article (like "Introduction to general relativity) may be the best solution. Avoid excessive wikilinking (linking within Wikipedia) as a substitute for parenthetic explanations such as the one in this sentence. Do not introduce new and specialized words simply to teach them to the reader when more common alternatives will do. When the notions named by jargon are too complex to explain concisely in a few parenthetical words, "write one level down. For example, consider adding a brief background section with {{"main}} tags pointing to the full treatment article(s) of the prerequisite notions; this approach is practical only when the prerequisite concepts are central to the exposition of the article's main topic and when such prerequisites are not too numerous. Short articles like "stubs generally do not have such sections.

Geographical items[edit]

Places should generally be referred to consistently by the same name as in the title of their article (see "Wikipedia:Naming conventions (geographic names)). Exceptions are made if there is a widely accepted historical English name appropriate to the given context. In cases where such a historical name is used, it should be followed by the modern name in round brackets (parentheses) on the first occurrence of the name in applicable sections of the article. This resembles linking; it should not be done to the detriment of style. On the other hand, it is probably better to provide such a variant too often than too rarely. If more than one historical name is applicable for a given context, the other names should be added after the modern English name, that is: "historical name (modern name, other historical names)".

Media files[edit]



Other media files[edit]

Other media files include video and audio files. Style recommendations for such files largely follow recommendations for image files (as far as applicable).

Avoid using images to convey text[edit]


Textual information should almost always be entered as text rather than as an image. True text can be colored and adjusted with "CSS tags and templates, but text in images cannot be. Images are not searchable, are slower to download, and are unlikely to be read as text by devices for the visually impaired. Any important textual information in an image should also appear in the image's alt text, caption, or other nearby text.

For entering textual information as audio, see "Wikipedia:WikiProject Spoken Wikipedia.



Photographs and other graphics should have captions, unless they are unambiguous depictions of the subject of the article or when they are "self-captioning" images (such as reproductions of album or book covers). In a biography article no caption is necessary for a portrait of the subject pictured alone; but one might be used to give the year, the subject's age, or other circumstances of the portrait along with the name of the subject.

Formatting of captions[edit]

Bulleted and numbered lists[edit]




Make "links only where they are relevant and helpful in the context: Excessive use of hyperlinks can be distracting and may slow the reader down. Redundant links (like the one in the tallest people on "Earth) clutter the page and make future maintenance harder. High-value links that are worth pursuing should stand out clearly.

Linking to sections: A hash sign (#) followed by the appropriate heading will lead to a relevant part of a page. For example, [[Apostrophe#Use in non-English names]] links to a particular section of the article "Apostrophe.

Initial capitalization: Wikipedia's "MediaWiki software does not require that wikilinks begin with an upper-case character. Only capitalize the first letter where this is naturally called for, or when specifically referring to the linked article by its name: "Snakes are often "venomous, but "lizards only rarely (see "Poison).

Check links: Ensure that the destination is the intended one; many dictionary words lead to disambiguation pages and not to complete or well-chosen articles.

External links[edit]

External links should not normally be used in the body of an article. Instead, articles can include an External links section at the end, pointing to further information outside Wikipedia as distinct from citing sources. The standard format is a primary heading, ==External links==, followed by a bulleted list of links. Identify the link and briefly indicate its relevance to the article. For example:

  • * [http://history.nih.gov/exhibits/history/index.html History of NIH]
  • * [http://nih.gov/ National Institutes of Health homepage]

These will appear as:

Where appropriate, use "external link templates such as {{"Official website}} and {{"URL}}.

Add external links with discretion; Wikipedia is "not a link repository.


Keep markup simple[edit]


Other things being equal, keep "markup simple. This makes wikitext easier to understand and edit, and the results seen by the reader more predictable. Use HTML and CSS markup sparingly.

An "HTML character entity is sometimes better than the equivalent Unicode character, which may be difficult to identify in edit mode; for example, &Alpha; is explicit whereas Α (the upper-case form of Greek α) may be misidentified as the Latin A.

Formatting issues[edit]

Modifications in font size, blank space, and color (see § Color coding) are an issue for the Wikipedia site-wide "style sheet, and should be reserved for special cases only.

Typically, the use of custom font styles will:

Outside article text, different font sizes are routinely used in navigation templates and "infoboxes, tables (especially in larger ones), and some other contexts where alternatives are not available (such as table captions). Specify font sizes relatively (for example in CSS with font-size: 85%) rather than absolutely (like font-size: 8pt).

Color coding[edit]


Do not use color alone to mark differences in text: they may be invisible to people with "color blindness and useless in black-and-white printouts or displays.

Choose colors that are distinguishable by readers with the commonest form of colorblindness, such as "maroon and "teal; and additionally mark the differences with change of font or some other means ("maroon and alternative font face, "teal). Avoid low contrast between text and background colors. Viewing the page with Toptal can help with the choice of colors. See also "color coding.

Even for readers with unimpaired color vision, excessive background shading of table entries impedes readability and recognition of Wikilinks. Background color should be used only as a supplementary visual cue, and should be subtle (consider using lighter, less-dominant "pastel hues) rather than glaring.

Scrolling lists and collapsible content[edit]


"Scrolling lists, and collapsible templates that toggle text display between hide and show, can interfere with readers' ability to access our content. Such mechanisms are "not to be used to conceal "spoiler" information. Templates are "not normally used to store article text at all, as it interferes with editors' ability to find and edit it.

When such features are used, take care that the content will still be "accessible on devices that do not support JavaScript or CSS, and to the 45% (and climbing) of Wikipedia readers who use the "mobile version of the site,[r] which has a limited set of features. Mobile ability to access the content in question is easy to test with the "Mobile view" link at the bottom of each page.[s]

Collapsible templates should not conceal article content by default upon page loading. This includes "reference lists, "tables and "lists of article content, "image galleries, and "image captions. In particular, note that while some templates support a collapsible parameter or manually-added CSS class, and this is permissible, the collapsed, mw-collapsed, and autocollapse states should not be used in articles to pre-emptively force the closure of these elements, except as noted below. Any information hidden in this way when the page loads will be irreversibly invisible to the aforementioned classes of users, as well as a growing number of low-bandwidth users in Asia who reach a Wikipedia article via Google.[t] Several other CSS classes, used manually or by templates, will render content inaccessible to mobile users.[u]

Collapsed or auto-collapsing cells or sections may be used with tables if it simply repeats information covered in the main text (or is purely supplementary, e.g. several past years of statistics in collapsed tables for comparison with a table of uncollapsed current stats). Auto-collapsing is often a feature of "navboxes. A few "infoboxes also use pre-collapsed sections for infrequently accessed details. If information in a list, infobox, or other non-navigational content seems extraneous or trivial enough to inspire pre-collapsing it, consider raising a discussion on the article (or template) talk page about whether it should be "included at all. If the information is important and the concern is article density or length, consider "dividing the article into more sections, integrating "unnecessarily list-formatted information into the article prose, or "splitting the article.

Invisible comments[edit]


Editors use "invisible" comments – not shown in the rendered page seen by readers of the article, but visible in the wiki source when an editor opens the article for editing – to communicate with one other.

Invisible comments are useful for alerting other editors to issues such as common mistakes that regularly occur in the article, a section title being the target of an incoming link, or pointing to a discussion that established a consensus relating to the article. They should not be used to instruct other editors not to perform certain edits, although where existing consensus is against making such an edit, they may usefully draw the editor's attention to that. Avoid adding too many invisible comments because they can clutter the wiki source for other editors. Check that your invisible comment does not change the formatting, for example by introducing unwanted white space in the rendered page.

To leave an invisible comment, enclose the text you intend to be read only by editors between <!-- and -->. For example:

This notation can be inserted with a single click in "wiki markup, just under the edit pane in edit mode.


Pronunciation in Wikipedia is indicated in the "International Phonetic Alphabet (IPA). In most situations, for ease of understanding by the majority of readers and across variants of the language, "quite broad IPA transcriptions are best for English pronunciations. See "Help:IPA/English and "Help:IPA (general) for keys, and {{"IPA}} for templates that link to these keys. For English pronunciations, "pronunciation respellings may be used in addition to the IPA.

Other community standards[edit]

Guidelines within the Manual of Style[edit]

(Links to policy and guidelines on specific questions)




  1. ^ This is a matter of policy at "WP:Consensus § Level of consensus: "Consensus among a limited group of editors, at one place and time, cannot override community consensus on a wider scale. For instance, unless they can convince the broader community that such action is right, participants in a wikiproject cannot decide that a Wikipedia policy or guideline does not apply to articles within its scope." And: "Wikipedia has a higher standard of participation and consensus for changes to policies and guidelines than to other types of pages."
  2. ^ a b c d Wikipedia uses "sentence case for sentences, "article titles, "section titles, "table headers, "image captions, "list entries (in most cases), and entries in "infoboxes and similar templates, among other things. Any instructions in MoS about the start of a sentence apply to items using sentence case.
  3. ^ Using phrases like In early life is acceptable for section headings.
  4. ^ a b c Typographical, or curly, quotation marks and apostrophes might be read more efficiently, and many think they look better. However, for practical reasons the straight versions are used on the English Wikipedia.
    • Consistency keeps searches predictable. Though most browsers don't distinguish between curly and straight marks, Internet Explorer still does (as of 2016), so that a search for Alzheimer's disease will fail to find Alzheimer’s disease and vice versa.
    • Straight quotation marks are easier to type reliably on most platforms.
    • "MediaWiki's use of series of single quotes to create italics and boldface makes use of these features complicated and error-prone with content that begins or ends with apostrophes.
  5. ^ The top-level heading is used only in the auto-generated page title.
  6. ^ A comment outside the == == disrupts section edits and their edit summaries, and even heading display. For example, if one clicks the edit section button, the section heading is not automatically added to the edit summary; or in some cases, the edit section button fails to appear at all.
  7. ^ Wikipedia has long recognized "Oxford spelling as a distinct English variety (see {{"Oxford spelling}}). A British English article using -ize spellings should not be converted to -ise, or vice versa, without consensus. A similar situation applies to use of "IUPAC spelling of chemistry terms ({{"IUPAC spelling}}, {{"IUPAC spelling US}}). Also, Canadian orthography has been in flux since the 1990s; which spelling is current in 2018 Canadian English may require research; when in doubt, normalize for consistency within the article, over other concerns.
  8. ^ News publications have often retained "U.S.", with the dots, because the frequent use of ALL-CAPS style for headlines leads to an ambiguity between "US" and "us". Some retain the "U.S." spelling in running text for consistency, but many journalism publishers have abandoned this even in the United States. Wikipedia does not use all-caps titles or headings, so the ambiguity concern does not apply here.
  9. ^ The space produced by the {{"' "}} and {{"" '}} templates is done with "CSS, is not a space character, and does not permit a line break between those marks.
  10. ^ Double quotation marks are preferred to single because:
    • They are immediately distinguishable from apostrophes:
      • She wrote that 'Cleanthes' differs from the others', but neither opinion may represent Hume's' (slows the reader down).
      • She wrote that "Cleanthes' differs from the others', but neither opinion may represent Hume's" (clearer).
    • Most browsers distinguish single and double quotation marks. Searches for "must see" attractions may fail to find 'must see' attractions.
  11. ^ "Series title italicized" is using series in the North American sense, i.e. the entire show as a whole. A season (series in the British sense) with its own title uses quotation marks for that title, as a sub-work.)
  12. ^ In some styles of writing, which Wikipedia might be quoting, a parenthetically enclosed sentence within another sentence may have a question mark or exclamation mark added, but not a period:
    Alexander then conquered (who would have believed it?) most of the known world.
    This style is not used in Wikipedia's own voice, as it is not encyclopedic but opinion-piece style.
  13. ^ A comma-introduced parenthetical can also be closed by another punctuation mark that takes the place of the second comma in the pair, such as a colon, semicolon, parenthetical dash, round bracket, or sentence-terminal punctuation. Example: The franchise locations in London, Ontario – both of which went bankrupt – were closed in 1998.
  14. ^ These colon rules apply to grammatical use of the colon, not to "symbolic use with numbers, as in a 3:1 ratio.
  15. ^ Specifically, compound "attributives, which are modifiers of a noun that occur within the "noun phrase. (See "hyphenated compound modifiers.)
  16. ^ It is not logically possible to have a "12–35 victory", except in a game where a lower score is better. Otherwise, use a construction like Clovis beat Portales, 35–12, or Jameson lost the election, 2345 votes to 6789, to Garcia, with parties, result, and number order in logical agreement.
  17. ^ a b "Passive voice is used much more frequently in encyclopedic writing than in most other forms, in which it may be frequently advised against. In an encyclopedic context, its careful use not only avoids inappropriate first- and second-person constructions, but also prevents making statements in the encyclopedia's own voice which represent assumption rather than certainty. For example, there's a significant difference between "He was convicted of embezzling government funds" and "He embezzled government funds", especially in a legal system with low standards of proof and due process. Passive voice should still be avoided when it is not needed; write Germany invaded Poland in 1939, not Poland was invaded by Germany in 1939.
  18. ^ See the "Wikimedia Report Card", updated at the end of each month with total and mobile-only pageviews. This is just a "hit" counter; in reality, a majority of our readers access Wikipedia via mobile devices at least some of the time.
  19. ^ The "Mobile view" feature shows the article as it currently exists. If considering a change that could have mobile accessibility implications, please save the change first in a "user sandbox and test the mobile version of that. A page's mobile version can also be accessed by changing the en.wikipedia.org in the address bar to en.m.wikipedia.org and loading that version of the URL. Note also that viewing the normal "desktop" version of the website on a mobile device is not viewing the mobile version of the site, though (depending on mobile browser and what transcoding it is doing) this may be a worthwhile test for some broader accessibility matters, especially on tablets, which do not always use the mobile version of Wikipedia.
  20. ^ As noted, CSS and JavaScript support are required to operate the show/hide toggle. Moreover, hidden content is not available in the mobile version of Wikipedia even on devices that have that support, because the mobile version's servers strip that content out before sending the page. Starting in 2016, Google has launched a Google User Content service that, like the earlier Google Lite and Google Web Transcoder, will strip hidden material from pages when they are accessed through Google searches, before content is delivered to users with slow connections. The service has already been deployed in India (where English is a major language) and Indonesia, with additional national markets planned for 2016 and forward. These services also completely strip out navboxes. [1] [2]
  21. ^ Applying, or using a template that applies, any of the following CSS classes will cause the affected content to be inaccessible to mobile users, and this list may not be exhaustive: ambox, navbox, vertical-navbox, topicon, metadata, nomobile, collapsed, mw-collapsed, and (when triggered) autocollapse.
