Coptic and demotic Egyptian are very similar to the earlier Egyptian language written in the hieroglyphic script. Coptic flourished as a literary language from the 2nd to 13th centuries, and its Bohairic dialect continues to be the liturgical language of the Coptic Orthodox Church of Alexandria. It was supplanted by Egyptian Arabic as a spoken language toward the early modern period. The Copts have tried to revive the language since the 19th century.
