Djerv

Djerv (Majuscule: Ꙉ, Minuscule: ꙉ ) is one of the Cyrillic alphabet letters that was used in Old Cyrillic. It was used in many early Serbo-Croatian monuments to represent the sounds /dʑ/ and /tɕ/ (modern đ/ђ and ć/ћ). It exists in the Cyrillic Extended-B table as U+A648 and U+A649. It is the basis of the modern letters Ћ and Ђ; the former was in fact a direct revival of djerv and was considered the same letter.
