Language groups[edit]

Most languages spoken in Africa belong to one of three large language families: Afroasiatic, Nilo-Saharan, and Niger–Congo. Another hundred belong to small families such as Ubangian (sometimes grouped within Niger-Congo) and the various families called Khoisan, or the Indo-European and Austronesian language families which originated outside Africa; the presence of the latter two dates to 2,600 and 1,000 years ago, respectively. In addition, African languages include several unclassified languages and sign languages.
