O (О о; italics: О о) is a letter of the Cyrillic script.

O commonly represents the close-mid back rounded vowel /o/, like the pronunciation of ⟨o⟩ in Scottish English "go".

History

The Cyrillic letter O was derived from the Greek letter Omicron (Ο ο).

Form

Modern fonts

In modern-style typefaces, the Cyrillic letter O looks exactly like the Latin letter O ⟨O o⟩ and the Greek letter Omicron ⟨Ο ο⟩.

Church Slavonic printed fonts and Slavonic manuscripts

Historical typefaces (like poluustav (semi-uncial), a standard font style for the Church Slavonic typography) and old manuscripts represent several additional glyph variants of Cyrillic O, both for decorative and orthographic (sometimes also "hieroglyphic"[1]) purposes, namely:

Usage

In Russian, O is used word-initially, after another vowel, and after non-palatalized consonants. Because of a vowel reduction processes, the Russian /o/ phoneme may have a number of pronunciations in unstressed syllables, including [ɐ] and [ə].

In Macedonian the letter represents the sound /ɔ/.

In Tuvan the Cyrillic letter can be written as a double vowel.[2][3]
