{{distinguish|text=the Latin letter O}}{{Cyrillic script navbox|Heading=Cyrillic letter O| Image=Cyrillic letter O - uppercase and lowercase.svg|size=100px| uuc=041E|ulc=043E|numeral=70|sound = {{IPA|[o]}}}} O (О о; italics: О о) is a letter of the Cyrillic script. O commonly represents the close-mid back rounded vowel {{IPA|/o/}}, like the pronunciation of {{angle bracket|o}} in Scottish English "go". HistoryThe Cyrillic letter O was derived from the Greek letter Omicron (Ο ο). The name of O in the Early Cyrillic alphabet was {{Script|Cyrs|онъ}} (onŭ), meaning "he" or "it". In the Cyrillic numeral system, O had a value of 70. FormModern fontsIn modern-style typefaces, the Cyrillic letter O looks exactly like the Latin letter O {{angle bracket|O o}} and the Greek letter Omicron {{angle bracket|Ο ο}}. Church Slavonic printed fonts and Slavonic manuscriptsHistorical 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: - broad variant (Ѻ/ѻ), used mostly as a word initial letter (see Broad On for more details);
- narrow variant, being used now in Synodal Church Slavonic editions as the first element of digraph Oy/oy (see Uk (Cyrillic) for more details), and in the editions of Old Believers for unstressed "o" as well;
- variant with a cross inside (Crossed O), Ꚛ, used in certain manuscripts as the initial letter of words окрестъ 'around, nearby' (the root of this Slavonic word, крест, means 'cross') and округъ 'district, neighbourhood' with their derivatives;
- "eyed" variant (Monocular O) with a dot inside (Ꙩ/ꙩ), used in certain manuscripts in spelling of word око 'eye' and its derivatives. In many other texts, including the birchbark letters, the monocular O was not used as a hieroglyph but largely as a synonym of Broad On signalling the word-initial position;
- "two-eyed" variants (Binocular O) with two dots inside (Ꙫ/ꙫ or Ꙭ/ꙭ), also double "O" without dots inside were used in certain manuscripts in spelling of dual/plural forms of the words with the same root 'eye';
- "many-eyed" variant (Multiocular O), ꙮ, used in certain manuscripts in spelling of the same root when embedded into word многоочитый 'many-eyed' (an attribute of seraphs).
UsageIn Russian, O is used word-initially, after another vowel, and after non-palatalized consonants. Because of a vowel reduction processes, the Russian {{IPA|/o/}} phoneme may have a number of pronunciations in unstressed syllables, including {{IPA|[ɐ]}} and {{IPA|[ə]}}. In Macedonian the letter represents the sound /ɔ/. In Tuvan the Cyrillic letter can be written as a double vowel.[2][3] Related letters and other similar characters- Ο ο : Greek letter Omicron
