U+2C20 "Ⱐ" Glagolitic Capital Letter Yeri Unicode Character

U+2C20 "Ⱐ" Glagolitic Capital Letter Yeri is a character from the Glagolitic script, an early Slavic alphabet created in the 9th century by Saints Cyril and Methodius. This specific letter represents the vowel sound /ɯ/ or a similar high back unrounded vowel, and it is the uppercase version of its lowercase counterpart U+2C50 "ⱐ". Historically used in Old Church Slavonic manuscripts, the Glagolitic script was eventually largely replaced by the Cyrillic alphabet, though it remained in liturgical use in some regions. The capital Yeri is notable for its distinct shape and its role in the phonetic system of the Glagolitic alphabet, making it an important subject of study for paleographers and linguists working with early Slavic texts.
