Kwʼadza (Qwadza), or Ngomvia, is an extinct Afroasiatic language formerly spoken in Tanzania in the Mbulu District.
[1] Kwʼadza is poorly attested, and apart from perhaps being close to Aasax, its classification is not certain.
Although it has a large number of identifiably Cushitic roots, the non-Cushitic numerals itame 'one' and beʼa ~ mbɛa 'two' suggest a connection with Hadza, while haka 'four' suggests a connection with Sandawe.
It is possible that Kwʼadza borrowed e.g. 'four' from Sandawe, but also that it was a non-Cushitic language whose speakers were undergoing language shift to Cushitic when it was recorded.
[citation needed] The phonology is not certain, but the following has been suggested (Ehret 1980): /ɡ/ and /l/ have the allophones [dʒ] and [ɽ] before front vowels.
