Ý (ý) is a letter of Old Norse, Icelandic, Kazakh, Vietnamese,and Faroese alphabets, as well as in Turkmen language. In Czech and Slovak languages it represents a long form of the vowel y. Originally, the letter Ý was formed from the letter Y and an acute accent.
In Icelandic, Ý is the 29th letter of the alphabet, between Y and Þ. It is read as /i/ (short) or /iː/ (long).
In Turkmen, Ý represents the consonant /j/, as opposed to Y, which represents the vowel sound /ɯ/.
In Kazakh, Ý is the 29th letter of the Latin alphabet and represents /w/ (or /ʊw/ or /ʉw/).
In Vietnamese, Ý means "Italy". The word is a shortened form of Ý Đại Lợi, which comes from Chinese 意大利 (Yìdàlì in Mandarin, a phonetic rendering of the country's name).
Ý does not exist in Modern Spanish, but the accented letter ý can be found in the proper name Aýna, a village in Spain. Nevertheless, it was used in Early Modern Spanish.
