The Coptic script is the script used for writing the Coptic language, the most recent development of Egyptian. The repertoire of glyphs is based on the uncial Greek alphabet, augmented by letters borrowed from the Egyptian Demotic. It was the first alphabetic script used for the Egyptian language. There are several Coptic alphabets, as the script varies greatly among the various dialects and eras of the Coptic language.
