Copts are a Christian ethnoreligious group indigenous to North Africa who have primarily inhabited the area of modern Egypt since antiquity. They are the largest Christian denomination in Egypt and the Middle East, as well as in Sudan and Libya. Copts in Egypt account for roughly 5–15 percent of the Egyptian population; Copts in Sudan account for 1 percent of the Sudanese population, while Copts in Libya similarly account for 1 percent of the Libyan population.

Coptic is a group of closely related Egyptian dialects, representing the most recent developments of the Egyptian language, and historically spoken by the Copts, starting from the third century AD in Roman Egypt. Coptic was supplanted by Arabic as the primary spoken language of Egypt following the Arab conquest of Egypt and was slowly replaced over the centuries. Coptic has no native speakers today, although it remains in daily use as the liturgical language of the Coptic Orthodox Church and of the Coptic Catholic Church. Innovations in grammar and phonology and the influx of Greek loanwords distinguish Coptic from earlier periods of the Egyptian language. It is written with the Coptic alphabet, a modified form of the Greek alphabet with several additional letters borrowed from the Demotic Egyptian script.
