ǀXam language
ǀXam (pronounced [ǀ͡xam] , in English as  KAHM) is an extinct language (or possibly cluster of languages) of South Africa formerly spoken by the ǀXam-ka ǃʼē. It is part of the ǃUi branch of the Tuu languages and closely related to the moribund Nǁng language. Much of the scholarly work on ǀXam was performed by Wilhelm Bleek, a German linguist of the 19th century, who studied a variety of ǀXam spoken at Achterveld, and (with Lucy Lloyd) another spoken at Strandberg and Katkop while working with  ǁKábbo, Diaǃkwāin, ǀAǃkúṅta, ǃKwéite̥n ta ǁKēn, ǀHaṅǂkassʼō and other speakers. The surviving corpus of ǀXam comes from the stories told by and vocabulary recorded from these individuals in the Bleek and Lloyd Collection.
