Egyptian language

The Egyptian language, or Ancient Egyptian (r n kmt; 'speech of Egypt'), is an extinct branch of the Afro-Asiatic language family that was spoken in ancient Egypt. It is known today from a large corpus of surviving texts, which were made accessible to the modern world following the decipherment of the ancient Egyptian scripts in the early 19th century.

Egyptian is one of the earliest known written languages, first recorded in the hieroglyphic script in the late 4th millennium BC. It is also the longest-attested human language, with a written record spanning over 4,000 years. Its classical form, known as "Middle Egyptian," served as the vernacular of the Middle Kingdom of Egypt and remained the literary language of Egypt until the Roman period.

By the time of classical antiquity, the spoken language had evolved into Demotic: its formation and development as a separate language from the Old Egyptian was strongly influenced by Aramaic and Ancient Greek. By the Roman and Byzantine eras, the language later further diversified into various Coptic dialects written in the Greek alphabet. These were eventually supplanted by Arabic after the Muslim conquest of Egypt, although Bohairic Coptic remains in use as the liturgical language of the Coptic Church.

The Egyptian language branch belongs to the Afroasiatic language family. Among the typological features of Egyptian that are typically Afroasiatic are its fusional morphology, nonconcatenative morphology, a series of emphatic consonants, a three-vowel system /a i u/, a nominal feminine suffix *-at, a nominal prefix m-, an adjectival suffix -ī and characteristic personal verbal affixes. Of the other Afroasiatic branches, linguists have variously suggested that the Egyptian language shares its greatest affinities with Berber and Semitic languages, particularly Arabic (which is spoken in Egypt today) and Hebrew. However, other scholars have argued that the Egyptian language shared closer linguistic ties with northeastern African regions.

There are two theories that seek to establish the cognate sets between Egyptian and Afroasiatic, the traditional theory and the neuere Komparatistik, founded by Semiticist Otto Rössler. According to the neuere Komparatistik, in Egyptian, the Proto-Afroasiatic voiced consonants */d z ð/ developed into pharyngeal ⟨ꜥ⟩ /ʕ/: Egyptian ꜥr.t 'portal', Semitic dalt 'door'. The traditional theory instead disputes the values given to those consonants by the neuere Komparatistik, instead connecting ⟨ꜥ⟩ with Semitic /ʕ/ and /ɣ/. Both schools agree that Afroasiatic */l/ merged with Egyptian ⟨n⟩, ⟨r⟩, ⟨ꜣ⟩, and ⟨j⟩ in the dialect on which the written language was based, but it was preserved in other Egyptian varieties. They also agree that original */k g ḳ/ palatalise to ⟨ṯ j ḏ⟩ in some environments and are preserved as ⟨k g q⟩ in others.

The Egyptian language has many biradical and perhaps monoradical roots, in contrast to the Semitic preference for triradical roots. Egyptian is probably more conservative, and Semitic likely underwent later regularizations converting roots into the triradical pattern.

Although Egyptian is the oldest Afroasiatic language documented in written form, its morphological repertoire is very different from that of the rest of the Afroasiatic languages in general, and Semitic languages in particular. There are multiple possibilities: perhaps Egyptian had already undergone radical changes from Proto-Afroasiatic before it was recorded; or the Afroasiatic family has so far been studied with an excessively Semitocentric approach; or, as G. W. Tsereteli suggests, Afroasiatic is a sprachbund, rather than a true genetic language family.

The Egyptian language can be grouped thus:
