Coptic

Coptic is spoken liturgically in the Coptic Orthodox and Coptic Catholic Church (along with Modern Standard Arabic). The language is spoken only in Egypt and historically has had little influence outside of the territory, except for monasteries located in Nubia (which straddles modern Egypt and Sudan). Coptic's most noticeable linguistic influence has been on the various dialects of Egyptian Arabic, which is characterised by a Coptic substratum in lexical, morphological, syntactical, and phonological features.

The Egyptian language may have the longest documented history of any language, from Old Egyptian, which appeared just before 3200 BC, to its final phases as Coptic in the Middle Ages. Coptic belongs to the Later Egyptian phase, which started to be written in the New Kingdom of Egypt. Later Egyptian represented colloquial speech of the later periods. It had analytic features like definite and indefinite articles and periphrastic verb conjugation. Coptic, therefore, is a reference to both the most recent stage of Egyptian after Demotic and the new writing system that was adapted from the Greek alphabet.

In the early 20th century, some Copts tried to revive the Coptic language, but they were unsuccessful. In the second half of the 20th century, Pope Cyril VI of Alexandria started a national Church-sponsored movement to revive Coptic. Several works of grammar were published, including a more comprehensive dictionary than had been formerly available. The scholarly findings of the field of Egyptology and the inauguration of the Institute of Coptic Studies further contributed to the renaissance. Efforts at language revitalisation continue to be undertaken, and have attracted the interest of Copts and linguists in and outside of Egypt.

There is little written evidence of dialectal differences in the pre-Coptic phases of the Egyptian language due to the centralised nature of the political and cultural institutions of ancient Egyptian society. However, literary Old and Middle (Classical) Egyptian represent the spoken dialect of Lower Egypt around the city of Memphis, the capital of Egypt in the Old Kingdom. Later Egyptian is more representative of the dialects spoken in Upper Egypt, especially around the area of Thebes as it became the cultural and religious center of the New Kingdom. Coptic more obviously displays a number of regional dialects that were in use from the coast of the Mediterranean Sea in northern Egypt, south into Nubia, and in the western oases. However, while many of these dialects reflect actual regional linguistic (namely phonological and some lexical) variation, they mostly reflect localized orthographic traditions with very little grammatical differences.

Coptic uses a writing system almost wholly derived from the Greek alphabet, with the addition of a number of letters that have their origins in Demotic Egyptian. This is comparable to the Latin-based Icelandic alphabet, which includes the runic letter thorn. There is some variation in the number and forms of these signs depending on the dialect. Some of the letters in the Coptic alphabet that are of Greek origin were normally reserved for Greek words. Old Coptic texts used several graphemes that were not retained in the literary Coptic orthography of later centuries. In Sahidic, syllable boundaries may have been marked by a supralinear stroke ⟨◌̄⟩, or the stroke may have tied letters together in one word, since Coptic texts did not otherwise indicate word divisions. Some scribal traditions use a diaeresis over the letters ⲓ and ⲩ at the beginning of a word or to mark a diphthong. Bohairic uses a superposed point or small stroke known as ϫⲓⲛⲕⲓⲙ (jinkim, "movement"). When jinkim is placed over a vowel it is pronounced independently, and when it is placed over a consonant a short ⲉ precedes it.
