Egyptian language
Coptic

Coptic is the name given to the late Egyptian vernacular when it was written in a Greek-based alphabet, the Coptic alphabet; it flourished from the time of Early Christianity (c. 31/33–324), but Egyptian phrases written in the Greek alphabet first appeared during the Hellenistic period c. 3rd century BC, with the first known Coptic text, still pagan (Old Coptic), from the 1st century AD.

Coptic survived into the medieval period, but by the 16th century was dwindling rapidly due to the persecution of Coptic Christians under the Mamluks. It probably survived in the Egyptian countryside as a spoken language for several centuries after that. Coptic survives as the liturgical language of the Coptic Orthodox Church and the Coptic Catholic Church.
