Iotated A (Ꙗ, ꙗ) is a letter of the Cyrillic script, used today only in Church Slavonic. It is unusual among early Cyrillic letters in having no direct counterpart in Glagolitic: Ⱑ (jat’) is used for both /ě/ and /ja/. Accordingly, many early Cyrillic texts (particularly those with Glagolitic antecedents) may use Ѣ for both these purposes; this practice continues into the fourteenth century, but is much more common in the South Slavonic than the East Slavonic area. Nevertheless, Ꙗ is attested in the earliest extant Cyrillic writings, including for example the Codex Suprasliensis and Savvina Kniga.
It continued in use in Serbian until the orthographical reforms of Vuk Karadžić, and in Bulgarian (where it also acquired a civil script glyph variant) until the late nineteenth century. Among the Eastern Slavs, the denasalisation of [ę], probably to [æ], and the subsequent coalescence of this sound with the /a/ phoneme meant that the letter Ѧ acquired the same function as Ꙗ, and the two came to be regarded as variants of the same letter. This is still the case in modern Church Slavonic, where, broadly speaking, Ꙗ is used initially and Ѧ elsewhere, though exceptionally they may be used to make other distinctions, such as that between ѧ҆зы́къ 'tongue' and ꙗ҆зы́къ 'people'.
