History of V

V (named vee /ˈviː/,) is the 22nd letter in the modern English alphabet and the ISO basic Latin alphabet.

The letter V comes from the Semitic letter Waw, as do the modern letters F, U, W, and Y. See F for details.

In Greek, the letter upsilon 'Υ' was adapted from waw to represent, at first, the vowel [u] as in "moon". This was later fronted to [y], the front rounded vowel spelled 'ü' in German.

In Latin, a stemless variant shape of the upsilon was borrowed in early times as V—either directly from the Western Greek alphabet or from the Etruscan alphabet as an intermediary—to represent the same /u/ sound, as well as the consonantal /w/. Thus, 'num' — originally spelled 'NVM' — was pronounced /num/ and 'via' was pronounced [ˈwia]. From the 1st century AD on, depending on Vulgar Latin dialect, consonantal /w/ developed into /β/ (kept in Spanish), then later to /v/.
