Coptic alphabet

The Coptic alphabet is based on the Greek alphabet. It is used for writing the Coptic language. The alphabet contains some extra letters for sounds used in Coptic but not in Greek. Those letters are derived from Demotic script, an Egypt alphabet.

The Coptic alphabet came into use during the 3rd century BC after the Greeks conquered Egypt. It is still used by the members of the Coptic Church to write their religious texts. All the Gnostic codices found in Nag Hammadi used the coptic alphabet.
