African dwelling by capital of Uganda (4)
I believe the answer is:
hutu
'african' is the definition.
(Hutus are an African ethnic group)
'dwelling by capital of uganda' is the wordplay.
'dwelling' becomes 'hut' (I have seen 'Crude dwelling ' mean 'hut' so perhaps 'dwelling' could also mean 'hut').
'by' means one lot of letters go next to another.
'capital of' says to take the initial letters.
The initial letter of 'uganda' is 'u'.
'hut'+'u'='HUTU'
(Other definitions for hutu that I've seen before include "Bantu speaker from Rwanda or Burundi" , "Rwandan or Burundian" , "A member of one Rwandan people" , "Africans" , "Member of a Bantu people living in Rwanda and Burundi" .)
