Ꙉ

Also known as Cyrillic letter djerv, djerv (Cyrillic), Cyrillic letter dierv, dierv (Cyrillic)

Djerv or Đerv (, ; Majuscule: Ꙉ, Minuscule: ꙉ) is one of the Cyrillic alphabet letters that was used in Old Cyrillic. It was used in many early Serbian monuments to represent the sounds and (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.
