Egyptian is the oldest known indigenous language of Egypt and a branch of the Afroasiatic language family. Written records of the Egyptian language have been dated from about 3400 BC, making it one of the oldest recorded languages known. Egyptian was spoken until the late 17th century AD in the form of Coptic. The national language of modern-day Egypt is Egyptian Arabic, which gradually replaced Coptic as the language of daily life in the centuries after the Muslim conquest of Egypt. Coptic is still used as the liturgical language of the Coptic Church. It has a handful of fluent speakers today.
