It is a name for Egyptians of the Christian faith and their Church. It is also the name for the last form of the ancient Egyptian language, which was written with mostly Greek letters. The Coptic language survives only as a liturgical language of the Coptic Orthodox Church.
Arabic script used extensively in early Islamic times which has specific proportional measurements, along with pronounced angularity and squareness; the name comes from the Iraqi city of Kufa.
The Ancient Egyptian language had a diverse vocabulary and precise syntax. It was written in Hieroglyphs and hieratic and demotic scripts. Egyptians tried to write their language using Greek letters, which became known as Coptic. Coptic was later replaced by the Arabic language. Kufic and Naskh scripts evolved as Arabic became the national language of Egypt.
Hieratic script was a cursive style of writing that was used mainly for religious texts. Surviving hieratic texts generally show careful calligraphy for literary or religious texts and very cursive shorthand for rapid writing.
The Arabic language entered Egypt starting in the seventh century AD/ first century after Hijra, with the spread of Islam. It was strengthened when Copts were forced to learn the Arabic language to keep their jobs in government offices.
