U+A658 "Ꙙ" Cyrillic Capital Letter Closed Little Yus Unicode Character
Unicode Version 17.0
Ꙙ
U+A658 "Ꙙ" Cyrillic Capital Letter Closed Little Yus is a historical glyph used in the early Cyrillic alphabet, representing a nasalized vowel sound similar to the modern Polish "ą" or the Russian "я" in certain phonetic contexts, but with a closed articulation. This letter is part of the Cyrillic Extended-B block and is rarely used outside of paleographic and scholarly texts, as it derives from the Glagolitic script and appears primarily in medieval Slavic manuscripts. Its uppercase form, "Ꙙ," corresponds to the lowercase "ꙙ," and it was employed to distinguish specific nasal vowels in Old Church Slavonic, though it has largely fallen out of use alongside related archaic letters like "Ꙗ" and "Ѧ".
