Khoisan
Khoisan or Khoe-Sān is an umbrella term for the various indigenous peoples of Southern Africa who traditionally speak non-Bantu languages, combining the Khoekhoen and the Sān peoples. Khoisan populations traditionally speak click languages. They are considered to be the historical communities throughout Southern Africa, remaining predominant until Bantu expansion and European colonisation. The Khoisan have lived in areas climatically unfavourable to Bantu (sorghum-based) agriculture, from the Cape region to Namibia and Botswana, where Khoekhoe populations of Nama and Damara people are prevalent groups. Considerable mingling with Bantu-speaking groups is evidenced by prevalence of click phonemes in many Southern African Bantu languages, including Xhosa.
