U (У у; italics: У у) is a letter of the Cyrillic script. It commonly represents the close back rounded vowel {{#invoke:IPA|main}}, somewhat like the pronunciation of Template:Angle bracket 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.
HistoryEdit
Historically, Cyrillic U evolved as a specifically East Slavic short form of the digraph Template:Angle bracket used in ancient Slavic texts to represent {{#invoke:IPA|main}}. The digraph was itself a direct loan from the Greek alphabet, where the combination Template:Angle bracket (omicron-upsilon) was also used to represent {{#invoke:IPA|main}}. Later, the o was removed, leaving the modern upsilon-only form.
Consequently, the form of the letter is derived from Greek upsilon Template:Angle bracket, which was parallelly also taken over into the Cyrillic alphabet in another form, as Izhitsa Template:Angle bracket. (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 other languagesEdit
In Tuvan the Cyrillic letter can be written as a double vowel.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite book</ref>
In certain languages, U is used to mark labialization.
