Cyrillic Small Letter A with Diaeresis

Cyrillic Small Letter A with Diaeresis at U+04D3 is a Cyrillic letter used for an a-like vowel that is distinguished from ordinary Cyrillic а by the diaeresis. It belongs to the Cyrillic block and is a lowercase alphabetic character, not a punctuation mark or accent typed separately. Its main use is in minority-language orthographies written with Cyrillic, especially in Chuvash, where ӓ represents a separate vowel sound in native words and names. It may appear in dictionaries, school materials, local publications, and linguistic examples when accurate spelling matters. The character is also used in language documentation, transliteration tables, and academic writing about Cyrillic alphabets to show the exact Chuvash letter rather than an а plus decorative dots. Its uppercase partner is Cyrillic Capital Letter A with Diaeresis, and it can be visually confused with Latin ä in mixed-script text even though they are different letters.
