Y is the twenty-fifth letter of the Latin alphabet. Its name in English is wy, sometimes spelled wye.
See V. In Ancient Greek Υψιλον (Ypsilon) was pronounced IPA [u], later on [y], now [i]. The Romans borrowed Y directly from the Greek, because they felt that V no longer adequately represented Greek [y].
The letter Y was used in Old English, as in Latin, with the value [y]; however, some think that this use was an independent invention in England created by stacking a V and an I, unrelated to the Latin use of the letter. By Middle English, [y] had lost its roundedness and become [i], and Y came to be used with the same values as I, [iː] and [ɪ] and [j]. Those dialects that retained [y] spelled it with U, under French influence. The Modern English use of Y is a direct continuation of this Middle English use. Thus the words myth [of Greek origin] and gift [of Old English origin], which originally contained high front rounded vowels, both have [ɪ] nowadays.
The English name of the letter, pronounced [waɪ], is of uncertain origin. It is possible that a former name [yː] broke in Old English to [wiː], which would regularly yield Modern English [waɪ].
With the introduction of printing, the letter Y was used by Caxton and other printers in England to represent the letter thorn (Þ, þ) which was lacking from continental typefaces, resulting in the use of ye for the word the.
In Spanish, Y is called i griega, in Catalan i grega, in Polish igrek, in French i grècque (all mean "Greek i"); in most other European languages the Greek name is still used; in German, for example, it's called upsilon. The letter Y was originally established as a vowel. In the standard English language, the letter Y is traditionally regarded as a consonant (as depicted in American game show Wheel of Fortune), but as a survey of almost any English text, including this one, will show, Y more commonly functions as a vowel.
Originally, Y was a vowel letter in Greek, representing [u] and later on, front rounded [y], becoming [i] in Modern Greek. It has the sound value [y] in German, in Finnish and the Scandinavian languages, where it can never be a consonant. In contrast, in the Latin transcription of Nenets (Nyenec) the letter "y" palatalizes the preceding consonant. The letter Y nicely shows how letters change their function. In Afrikaans, Y denotes the diphthong [EI], probably as a result of mixing lower case i and y or may derive from the IJ ligature. In Dutch, Y appears only in loanwords and names and is usually pronounced [i]. It is often left out of the Dutch alphabet and replaced with the "letter IJ". Italian, too, has Y only in very few loanwords.
In Castilian language, Y was used as a word-initial form of I that was more visible. German has used J in a similar way. Hence el Yugo y las Flechas was a symbol sharing the initials of Isabella I of Castile (Ysabel) and Ferdinand II of Aragon. This spelling was reformed by the Royal Spanish Academy and currently is only found in proper names spelt archaicly, such as Ybarra or CYII, the symbol of the Canal de Isabel II. X is also still used in Spanish with a different sound in some archaisms. In Spanish names, an y (meaning "and") can separate the father surname from the mother surname as in "Santiago Ramón y Cajal". Catalan names use i for this.
In the International Phonetic Alphabet, [y] corresponds to the close front rounded vowel, and [ʏ] corresponds to the near-close near-front rounded vowel.
