Yat or jat (Ѣ ѣ; italics: Ѣ ѣ) is the thirty-second letter of the old Cyrillic alphabet. It is usually romanized as E with a haček: Ě ě.
There is also another version of yat, the iotated yat (majuscule: ⟨Ꙓ⟩, minuscule: ⟨ꙓ⟩), which is a Cyrillic character combining a decimal I and a yat. There was no numerical value for this letter and it was not in the Glagolitic alphabet. It was encoded in Unicode 5.1 at positions U+A652 and U+A653.
