S. African language; Z (4)

I believe the answer is:

zulu

(Other definitions for zulu that I've seen before include "Ethnic group of southern Africa" , "Communications code for Z" , "Large ethnic group from eastern South Africa" , "S African warrior tribe" , "Radio communication's last letter - Southern African" .)

I've seen this clue in The Times.
