Analysis of information sources in references of the Wikipedia article "Egyptian language" in English language version.
The liturgy of the present day Coptic Orthodox Church in Egypt is written in a mixture of Arabic, Greek, and Bohairic Coptic, the ancient dialect of the Delta and the great monasteries of the Wadi Natrun. Coptic is no longer a living language.
The Egyptian-Coptic language is attested in a vast corpus of written texts that almost uninterruptedly document its lifetime over more than 4,000 years, from the invention of the hieroglyphic writing system in the late 4th millennium BCE, up to the 14th century CE. Egyptian is thus likely to be the longest-attested human language known.
