Dialects
Pre-Coptic Egyptian does not show great dialectal differences in the written language due to the centralized nature of Egyptian society. However, they must have existed in speech; this is evidenced by a letter from c. 1200 BCE complaining that the language of a correspondent is as unintelligible as the speech of a northern Egyptian to a southerner. Recently, some evidence of internal dialects has been found in pairs of similar words in Egyptian, which, 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 which was the main classical dialect and the northern Bohairic dialect which is currently used in Coptic Church services.
