The Tuu or Taa–ǃKwi languages are a language family
Language family
A language family is a group of languages related through descent from a common ancestor, called the proto-language of that family. The term 'family' comes from the tree model of language origination in historical linguistics, which makes use of a metaphor comparing languages to people in a...

Botswana

. The relationship between the two clusters is not doubted, but is not close. The name Tuu comes from a word for person common to both branches of the family. The Tuu languages form in turn one branch of a proposed Khoisan language family, and are called Southern Khoisan in that scenario. However, no convincing evidence has ever been produced for this classification.
  • Taa
    • ǃXóõ (5000 speakers. A dialect cluster.)
    • Lower Nossob
      Lower Nossob language
      Lower Nassob was a southern Khoisan language spoken along the Nossob River on the border of South Africa and Botswana, near Namibia. It was closely related to Taa.There are two attested dialects, ǀʼAuni and |Haasi ....

       (Extinct.)
    • ǁXegwi (Extinct.)


The ǃKwi branch of South Africa is moribund, with only one language remaining, Nǁng, and that with less than a dozen elderly speakers. ǃKwi languages were once widespread across South Africa; the most famous, ǀXam, was the source of the modern national motto of that nation, ǃke eː ǀxarra ǁke.

The Taa branch of Botswana is more robust, though it also has one surviving language, ǃXóõ, with 4200 speakers.

The family was once thought to include the (East) ǂHõã language, but this may instead be related to the Juu family

The Tuu languages, along with ǂHõã, are known for being the only languages in the world to have bilabial click
Bilabial click

Vowel
In phonetics, a vowel is a sound in spoken language, such as English ah! or oh! , pronounced with an open vocal tract so that there is no build-up of air pressure at any point above the glottis.

Because many of the Tuu languages became extinct with little record, there is considerable confusion as to which of their many names represented separate languages or even dialects. See List of Khoisan languages for some possibilities.
