U (У у; italics: У у) is a letter of the Cyrillic script. It commonly represents the close back rounded vowel {{IPA|/u/}}, somewhat like the pronunciation of {{angle bracket|oo}} in "boot" or "rule". The forms of the Cyrillic letter U are similar to the lowercase of the Latin letter Y (Y y; Y y), with the lowercase Cyrillic letter U's form being identical to that of small Latin letter Y.

History

Historically, Cyrillic U evolved as a specifically East Slavic short form of the digraph {{angle bracket|оу}} used in ancient Slavic texts to represent {{IPA|/u/}}. The digraph was itself a direct loan from the Greek alphabet, where the combination {{angle bracket|ου}} (omicron-upsilon) was also used to represent {{IPA|/u/}}. Later, the o was removed, leaving the modern upsilon-only form.

Consequently, the form of the letter is derived from Greek upsilon {{angle bracket|Υ υ}}, which was parallelly also taken over into the Cyrillic alphabet in another form, as Izhitsa {{angle bracket|Ѵ}}. (The letter Izhitsa was removed from the Russian alphabet in the orthography reform of 1917/19.)

It is normally romanised as "u", but in Kazakh, it is romanised as "w".

In the Cyrillic numeral system, the Cyrillic letter U had a value of 400.

In certain languages, U is used to mark labialization.
