The Khoisan languages (pejoratively often called Hottentott and Bushman languages) are spoken in Southern Africa by mostly small ethnic groups, partly having preserved a hunter-gatherer culture.
The Khoisan languages can be subdivided into three families. Genetic relationship between these three families can not be proven yet. Because all the Khoisan languages show clicks sounds as one of their major features, they are grouped together. This is also the reason why two "click-languages" spoken in East-Afrika (Hadza and Sandawe) have been grouped here.
The existing languages are classifiable as follows:
North Khoisan:
Southern Khoisan:
Central Khoisan:
At the University of Frankfurt am Main the person engaged in Khoisan linguistics is Prof. Rainer Vossen. Under his conduction a research project will be carried out which will establish a Public Accesible Language Database about Kxoe.
