Coptic Small Letter Dalda

It writes the consonant d inside Coptic words.

Greek spellings of Egyptian names in the seventh–sixth centuries BCE are the earliest roots of Coptic writing. Greek-letter writing for Egyptian became more systematic after Alexander the Great conquered Egypt. In the first century CE, Christian Egyptians used Greek letters with Demotic signs from an older Egyptian script to write sounds Greek lacked, including in sacred translations. Literary Coptic took shape around the turn of the third century CE.
