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'. 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.
Use in writing systems
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 // (as in 'duck'), though it retains its old pronunciation // 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 // (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 // in 'business' and // in 'bury'.
The letter ⟨u⟩ is used in the digraphs ⟨au⟩ //, ⟨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 // 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').
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.
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 (/i:/) 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 (/ɨ:/) and a short lowered close central unrounded vowel (/ɨ̞/), respectively. /u:/ and /ʊ/ are represented by ⟨w⟩.
The symbol 'U' is the chemical symbol for uranium.
