ǃKung (ǃXun), also known as Ju, is a dialect continuum (language complex) spoken in Namibia, Botswana, and Angola by the ǃKung people, constituting two or three languages. Together with the ǂʼAmkoe language, ǃKung forms the Kxʼa language family. ǃKung constituted one of the branches of the putative Khoisan language family, and was called Northern Khoisan in that scenario, but the unity of Khoisan has never been demonstrated and is now regarded as spurious. Nonetheless, the anthropological term "Khoisan" has been retained as an umbrella term for click languages in general. ǃKung is famous for its many clicks, such as the ǃ in its name, and has some of the most complex inventories of both consonants and vowels in the world. It also has tone and nasalization. For a description, see Juǀʼhoan. To pronounce ǃXuun (pronounced in Western ǃKung/ǃXuun) one makes a click sound before the x sound (which is like a Scottish or German ch), followed by a long nasal u vowel with a high rising tone. Names The term ǃKung, or variants thereof, is typically used when considering the dialects to constitute a single language; Ju tends to be used when considering them as a small language family. ǃKung is also sometimes used for the northern/northwestern dialects, as opposed to the well documented Juǀʼhoan dialects in the south(east); however speakers of nearly all dialects call themselves ǃKung. The spellings ǃXun and ǃXuun seen in recent literature are related to the Juǀʼhoan form spelled ǃXʼu(u)n in the 1975 orthography, or ǃKu(u)n in current orthography. Additional spellings are ǃHu, ǃKhung, ǃKu, Kung, Qxü, ǃung, ǃXo, Xû, ǃXû, Xun, ǃXung, ǃXũũ, ǃXun, ʗhũ:, and additional spellings of Ju are Dzu, Juu, Zhu. Speakers If the ǃKung dialects are counted together, they would make the third-most-populous click language after Khoekhoe and Sandawe. The most populous ǃKung variety, Juǀʼhoan, is perhaps tied for third place with Naro. Estimates vary, but there are probably around 15,000 speakers. Counting is difficult because speakers are scattered on farms, interspersed with speakers of other languages, but counts 9,000 in Namibia, 2,000 in Botswana, 3,700 in South Africa and 1,000 in Angola (down from perhaps 8,000 in 1975). Until the mid–late twentieth century, the northern dialects were widespread in southern and central Angola. However, most ǃKung fled the Angolan Civil War to Namibia (primarily to the Caprivi Strip), where they were recruited into the South African Defence Force special
