Afroasiatic

node · earth · North Africa, the Horn of Africa, Southwest Asia

The family spanning North Africa, the Horn of Africa and Southwest Asia, whose branches are conventionally given as Semitic, Egyptian, Berber, Chadic, Cushitic and — disputed — Omotic. It has the deepest continuous written record of any family on Earth: Egyptian is attested from around the beginning of the third millennium BCE and Akkadian not long after, so two branches are documented for roughly five thousand years. The family is bound together by grammatical evidence of the kind hardest to borrow, above all a shared system of prefixed and suffixed verb conjugation and a two-gender pattern in which the feminine is marked by a t element. Its homeland is genuinely open: the greatest branch diversity lies in Africa, which by the standard diversity argument favours an African origin, most often placed in the Horn or the eastern Sahara, while the Semitic branch's Asian distribution and the agricultural associations of some reconstructions have supported a Levantine case. Omotic's membership has been questioned repeatedly, and the family's time depth — plausibly beyond eight thousand years — sits at or past the limit where the comparative method retains resolution.
