Ju, Tuu & Khoe languages
Previously known as Khoesan (or Khoisan) languages, today these unique click languages are more accurately grouped into three distinct language families:
Ju (also known as Kx'a) language family
examples include: Ju|'hoansi, !Xun and ǂHoan
Tuu (also known as !Ui-Taa) language family
examples include: N|uu and Taa
Khoe (also known as Khoe-Kwadi or Khoeid) language family
examples include: Khoekhoe (Khoekhoegowab), Kora (!Ora), Khwe (Khwedam), Naro, Ts'ixa and Tshwa.
All three language families are endangered and despite extensive research in the field of linguistics around sustaining linguistic diversity, "Relatively little is known about Africa's endangered languages" (Kandybowicz & Torrence, 2017, synopsis)
Speakers of these languages are found in southern Africa in countries such as: Angola, Namibia, South Africa, Zambia and Zimbabwe
