|South Africa and Botswana|
|Linguistic classification||One of the world's primary language families (formerly considered Khoisan)|
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 are not demonstrably related to any other language family, however they do share a great many similarities to the languages of the Kxʼa family.
The Tuu languages were once thought to form a branch of the now-obsolete Khoisan language family and were called Southern Khoisan in that scenario.
- ǃKwi (ǃUi)
The Taa branch of Botswana is more robust, though it also has one surviving language, ǃXóõ, with 2,500 speakers.
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.
The Tuu languages, along with neighbouring ǂʼAmkoe, are known for being the only languages in the world to have bilabial clicks as distinctive speech sounds (apart from the extinct ritual jargon Damin of northern Australia, which was never anyone's mother tongue).
All languages in these three families also have tone.
