Largest tribe in South Africa

I believe the answer is:

zulu

(Other definitions for zulu that I've seen before include "African warrior under Chaka" , "S African warrior tribe" , "Bantu language; Z in radio communications" , "South African native" , "Yankee follower" .)

I've seen this clue in The Mirror.
