U+1E03C "𞀼" Modifier Letter Cyrillic Small O Unicode Character

Unicode Version 17.0

𞀼

U+1E03C "𞀼" Modifier Letter Cyrillic Small O is a specialized diacritical mark used in certain scholarly or phonetic contexts to modify the pronunciation or function of a preceding Cyrillic letter, typically indicating a reduced or shortened form of the vowel "o". This character belongs to the Cyrillic Extended D block, which contains various modifier letters designed for precise phonetic transcription of Slavic and other languages that use the Cyrillic script. Its small glyph shape allows it to be positioned above or attached to a base letter, functioning similarly to a superscript or combining mark without actually combining automatically. As a modifier rather than a standalone vowel, it helps linguists and language experts denote subtle articulatory features such as vowel gradation or reduced stress in historical or dialectal studies.
