Setback for West African, confusing endings of verb in East African capital (7)
I believe the answer is:
nairobi
'east african capital' is the definition.
(capital of Kenya)
I don't understand how the remainder of the clue works.
(Other definitions for nairobi that I've seen before include "East African capital" , "City of Kenya" , "Flat round object" , "Foreign capital" , "Kenya's capital city" .)
