Rwandan ethnic group (4)
I believe the answer is:
hutu
'rwandan ethnic group' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hutu that I've seen before include "A member of one Rwandan people" , "Africans" , "African" , "Member of a Bantu people living in Rwanda and Burundi" , "Rwandan or Burundian" .)
