In early Greek it was pronounced like English oo, IPA: [u] . In Classical Greek, it was pronounced like French u or German ü, IPA: [y] — a sound that is not found in most dialects of English. The Ancient Greek language is the historical stage in the development of the Hellenic language family spanning the Archaic (c English is a West Germanic language originating in England and is the First language for most people in the United Kingdom, the United States In Modern Greek it is pronounced like continental i or English ee, IPA: [i], and in diphthongs, [f] or [v]. Modern Greek (el Νέα Ελληνικά or el Νεοελληνική lit In ancient Greek it occurred in both long and short versions, but this distinction has been lost in Modern Greek.
As an initial letter in Classical Greek it always carried the rough breathing (equivalent to h) as reflected in the many Greek-derived English words, such as those that begin with hyper- and hypo-. The spiritus asper ( Latin for "rough breathing" δασὺ πνεῦμα dasỳ pneûma or daseîa) is a diacritical mark used in The Greek language has contributed to the English vocabulary in three ways directly as an immediate donor indirectly through other intermediate language(s This rough breathing was derived from an older pronunciation which used a sibilant instead; this sibilant was not lost in Latin, giving rise to such cognates as super- (for hyper-) and sub- (for hypo-). A sibilant is a type of Fricative or Affricate Consonant, made by directing a jet of air through a narrow channel in the Vocal tract towards
Upsilon participated as the second element in falling diphthongs, which have subsequently developed in various ways: for instance after alpha or epsilon it is pronounced [f] or [v].

The Roman Emperor Claudius proposed introducing a new letter into the Latin alphabet to approximate the sound of upsilon, but in due course the letter Y was adopted instead.

The name of the letter was originally just υ (y; also called hy, hence "hyoid", meaning "y-shaped"). It changed to υ ψιλόν, (u psilon, meaning 'simple u') to distinguish it from οι, which had come to have the same [y] pronunciation.  The name of the letter in modern Greek is pronounced /iː'psɪlɒn/ (in contrast to the letter Ε, which is pronounced /ɛ'psɪlɒn/). It is also rarely called "ypsilon" (/ɪ'psɪlɒn/) in English because of its resemblance to the Roman letter Y.
Four letters of the Latin alphabet arose from it: V and Y and, much later, U and W. V is the twenty-second letter in the modern Latin alphabet. Its name in English is spelled vee or occasionally ve (viː The letter Y is the twenty-fifth letter in the modern Latin alphabet. U is the twenty-first letter in the modern Latin alphabet. Its name in English is spelled u (juː W is the twenty-third letter in the Latin alphabet.
