Monocular O
Monocular O is one of the exotic glyph variants of Cyrillic letter O. This glyph variant was used in certain manuscripts in the root word , and also in some other functions, for example, in the word- and syllable-initial position. It is used in some late birchbark letters of the 14th and 15th centuries, where it is usually differentiated from a regular о, used after consonants, also by width, being a broad On with a dot inside.
It resembles the Latin letter for the bilabial click and the Gothic letter Hwair.
