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 'valor' and 'excuse' appeared as in modern printing, 'have' and 'upon' were printed 'haue' and 'vpon'. The first distinction between the letters 'u' and 'v' is recorded in a Gothic alphabet from 1980, 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 English
In English, the letter u has four primary pronunciations. There are "long" and "short" pronunciation. 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 (with the original long u being respelled ou), most commonly represents // (as in 'mule'), reducing to // after ar (as in 'rule') and sometimes (or optionally) after el (as in 'lute'), and after additional consonants in American English (see do–dew merger). (After ess, /sjuː, zjuː/ have assimilated to /ʃuː, ʒuː/.) In a few words, short 'u' represent 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'). U 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 other 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, for example.
