Iotated A is a letter of the Cyrillic script, built as a ligature of the letters І and А, and 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 may use Ѣ for both these purposes; this practice continued into the fourteenth century, but was 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.
