History[edit]

The letter u ultimately comes from the "Phoenician letter "waw by way of the letter "y. See the letter "y for details.

During the late "Middle Ages, two forms of 'v' developed, which were both used for its ancestor 'u' and modern 'v'. The pointed form 'v' was written at the beginning of a word, while a rounded form 'u' was used in the middle or end, regardless of sound. So whereas 'valour' and 'excuse' appeared as in modern printing, 'have' and 'upon' were printed 'haue' and 'vpon', respectively. The first recorded use of 'u' and 'v' as distinct letters is in a Gothic alphabet from 1386, where 'v' preceded 'u'. Printers eschewed capital 'U' into the 17th century and the distinction between the two letters was not fully accepted by the French Academy until 1762.[3]

Use in writing systems[edit]

Pronunciation of the name of the letter ⟨u⟩ in European languages

English[edit]

In "English, the letter ⟨u⟩ has four main pronunciations. There are "long" and "short" pronunciations. Short ⟨u⟩, found originally in closed syllables, most commonly represents "/ʌ/ (as in 'duck'), though it retains its old pronunciation "/ʊ/ after "labial consonants in some words (as in 'put') and occasionally elsewhere (as in 'sugar'). Long ⟨u⟩, found originally in words of French origin (the descendent of Old English long u was respelled as ⟨"ou⟩), most commonly represents "/juː/ (as in 'mule'), reducing to "// after ⟨r⟩ (as in 'rule') and sometimes (or optionally) after ⟨l⟩ (as in 'lute'), and after additional consonants in American English (see "do–dew merger). (After ⟨s⟩, /sjuː, zjuː/ have assimilated to /ʃuː, ʒuː/.) In a few words, short ⟨u⟩ represents other sounds, such as "/ɪ/ in 'business' and "/ɛ/ in 'bury'.

The letter ⟨u⟩ is used in the digraphs ⟨au⟩ "/ɔː/, ⟨ou⟩ (various pronunciations), and with the value of "long u" in ⟨eu⟩, ⟨ue⟩, and in a few words ⟨ui⟩ (as in 'fruit'). It often has the sound "/w/ before a vowel in the sequences ⟨qu⟩ (as in 'quick'), ⟨gu⟩ (as in 'anguish'), and ⟨su⟩ (as in 'suave'), though it is silent in final -que (as in 'unique') and in many words with ⟨gu⟩ (as in 'guard').

Additionally, the letter ⟨u⟩ is used in "text messaging and "internet and other written slang to denote 'you', by virtue of both being pronounced "/j/.

One thing to note is that certain varieties of the English language (i.e. "British English, "Canadian English, etc.) use the letter U in words such as colour, labour, valour, etc.; however, in "American English the letter is not used and said words mentioned are spelled as color and so on.

Other languages[edit]

In most languages that use the Latin alphabet, ⟨u⟩ represents the "close back rounded vowel /u/ or a similar vowel.[4]

In "French orthography the letter represents the "close front rounded vowel (/y/); /u/ is represented by ⟨ou⟩. In "Dutch and "Afrikaans, it represents either /y/, or a near-close near-front rounded vowel (/ʏ/); likewise the phoneme /u/ is represented by ⟨oe⟩. In "Welsh orthography the letter can represent a long "close front unrounded vowel (/iː/) or short "near-close near-front unrounded vowel (/ɪ/) in Southern dialects. In Northern dialects, the corresponding long and short vowels are a long "close central unrounded vowel (/ɨː/) and a short lowered close central unrounded vowel (/ɨ̞/), respectively. /uː/ and /ʊ/ are represented by ⟨w⟩.

Other uses[edit]

The symbol 'U' is the chemical symbol for "uranium.

In the context of Newtonian "mechanics 'U' is the symbol for the "potential energy of a system.

'u' is the symbol for the "atomic mass unit and 'U' is the symbol for one "Enzyme unit.

In "IPA, the "close back rounded vowel is represented by the lower case ⟨u⟩.

U is also the source of the mathematical symbol ∪, representing a "union. It is used mainly for "Venn diagrams and "geometry.

It is used as for micro- in metric measurements as a replacement for the Greek letter "μ (mu), of which it is a graphic approximation, when that Greek letter is not available, as in "um" for "μm (micrometer).

Some universities, such as the "University of Miami and the "University of Utah, are locally known as "The U".
