The Copt language (from the Arabian Kobt) represents the last stadium of the ancient Egyptian language, enlarged with some Greek and Latin words. It was written not in Hieroglyphic signs but in Greek letters. The Copta alphabet includes, beyond the twenty-four Greek letters, seven signs proceeding from the memothic (ancient Egyptian writing used by the people). They were destined to traduce proper sounds of the Egyptian language. The Copta writing started to be commonly used from the 3 Rd century. Since the Egypt's conquest by the Arabians in the 7 Th century, the Arabian overpasses the Copta language is popular access. This language was used in churches and convents liturgy language.
