U+A65F "ꙟ" Cyrillic Small Letter Yn Unicode Character

U+A65F "ꙟ" Cyrillic Small Letter Yn is a historical letter used in the Old Cyrillic alphabet, specifically designed to represent a nasalized vowel sound found in early Slavic languages, such as Old Church Slavonic. This character, which is part of the Cyrillic Extended-B block, corresponds to the uppercase form U+A65E "Ꙟ" and was employed primarily in medieval manuscripts before the sound it denoted gradually merged with other vowels in later Slavic linguistic development. Its usage is largely obsolete today, but it remains important for scholarly work in paleography and historical linguistics.
