Modern fonts

Church Slavonic printed fonts and Slavonic manuscripts

• broad variant, used mostly as a word initial letter ;
• narrow variant, being used now in Synodal Church Slavonic editions as the first element of digraph Oy/oy, and in the editions of Old Believers for unstressed "o" as well;
• variant with a cross inside, Ꚛ, used in certain manuscripts as the initial letter of words окрестъ 'around, nearby' and округъ 'district, neighbourhood' with their derivatives;
• "eyed" variant with a dot inside, 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 with two dots inside, 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, ꙮ, used in certain manuscripts in spelling of the same root when embedded into word многоочитый 'many-eyed'.
