Khoisan languages

The Khoisan languages ( KOY-sahn; also Khoesan or Khoesaan) are a sprachbund of African languages once classified together, originally by Joseph Greenberg. Khoisan is defined as those languages that have click consonants and do not belong to other African language families. For much of the 20th century, they were thought to be genealogically related to each other, but this is no longer accepted. They are now held to comprise three distinct language families and two language isolates. All but two Khoisan languages are indigenous to southern Africa; these are classified into three language families. The Khoe family appears to have migrated to southern Africa not long before the Bantu expansion. Ethnically, their speakers are the Khoekhoe and the San (Bushmen). Two languages of eastern Africa, those of the Sandawe and Hadza, were originally also classified as Khoisan, although their speakers are ethnically neither Khoekhoe nor San. Before the Bantu expansion, Khoisan languages, or languages like them, were likely spread throughout southern and eastern Africa. They are currently restricted to the Kalahari Desert, primarily in Namibia and Botswana, and to the Rift Valley in central Tanzania. Most of the languages are endangered, and several are moribund or extinct. Most have no written record. The only widespread Khoisan language is Khoekhoe (also known as Khoekhoegowab, Nàmá or Damara) of Namibia, Botswana and South Africa, with a quarter of a million speakers; Sandawe in Tanzania is second in number with some 40–80,000, some monolingual; and the ǃKung language of the northern Kalahari spoken by some 16,000 or so people. Language use is quite strong among the 20,000 speakers of Naro, half of whom speak it as a second language. Khoisan languages are best known for their use of click consonants as phonemes. These are typically written with characters such as ǃ and ǂ....
