Egyptian language
Dialects

Most hieroglyphic Egyptian texts are written in a literary prestige register rather than the vernacular speech variety of their author. As a result, dialectical differences are not apparent in written Egyptian until the adoption of the Coptic alphabet. Nevertheless, it is clear that these differences existed before the Coptic period. In one Late Egyptian letter (dated c. 1200 BC), a scribe jokes that his colleague's writing is incoherent like "the speech of a Delta man with a man of Elephantine."

Recently, some evidence of internal dialects has been found in pairs of similar words in Egyptian that, based on similarities with later dialects of Coptic, may be derived from northern and southern dialects of Egyptian. Written Coptic has five major dialects, which differ mainly in graphic conventions, most notably the southern Saidic dialect, the main classical dialect, and the northern Bohairic dialect, currently used in Coptic Church services.
