Cyrillic digraphs

O (О, о) is a letter of the Cyrillic alphabet, representing the vowel /o/ word-initially and after hard consonants. Because of vowel reduction processes, the Russian /o/ phoneme may have a number of pronunciations in unstressed syllables, including [ɐ] and [ə].

The letter's traditional name is on, meaning "he", or "that" (masculine noun) in Old Church Slavonic. It is derived from the Greek letter omicron (<Ο, ο>).

It looks exactly like the Latin letter <O>.

[edit] Broad On

Broad On (Ѻ ѻ) is a variation of the Cyrillic letter On (О, о) used in Church Slavonic:

• as the first letter of a word's root:
  • in the initial position (ѻгнь, ѻтрокъ),
  • after a prefix (праѻтецъ),
  • in compound words (ѻбоюдуѻстрый),
• in two geographical names (iѻрданъ—Jordan River, iѻппіа—city of Jaffa) and their derivatives,
• as the numerical sign to represent the number 70.

A misleading Unicode name of Broad On is Round Omega. (Notice that the Cyrillic Omega represents 800 instead of 70).
