U+046A "Ѫ" Cyrillic Capital Letter Big Yus Unicode Character

U+046A "Ѫ" Cyrillic Capital Letter Big Yus is a historic letter from the early Cyrillic alphabet, representing a nasalized back vowel that was used primarily in Old Church Slavonic and other early Slavic languages. This character, along with its lowercase counterpart (U+046B "ѫ"), was employed to denote a sound similar to the modern Polish "ą" or French "on", but it gradually fell out of use as the nasal vowels disappeared from most Slavic languages over the centuries. Today, "Big Yus" is rarely encountered outside of scholarly editions of medieval texts, linguistic studies, or specialized liturgical contexts, making it a notable relic of the phonetic diversity of early written Slavic.
