Yat

Yat or Jat (Ѣ ѣ; italics: Ѣ ѣ) is the thirty-second letter of the old Cyrillic alphabet. Its name in Old Church Slavonic is jěd’ (ѣдь) or iad’ (ꙗдь). In the common scientific Latin transliteration for old Slavic languages, the letter is represented by e with caron: ě (taken from the Czech alphabet).
