African is talking to whom? (4)
I believe the answer is:
hutu
'african' is the definition.
(Hutus are an African ethnic group)
'talking to whom?' is the wordplay.
'talking' indicates a 'sounds like' (homophone) clue.
'to whom?' becomes 'who to'.
'whoto' is a homophone of 'HUTU'.
'is' acts as a link.
(Other definitions for hutu that I've seen before include "Member of a Bantu people living in Rwanda and Burundi" , "A member of one Rwandan people" , "African" , "Bantu speaker from Rwanda or Burundi" , "Africans" .)
