The capital of Kenya (7)
I believe the answer is:
nairobi
'the capital of kenya' is the definition.
('Nairobi' can be a synonym of 'capital of kenya')
This is all the clue.
(Other definitions for nairobi that I've seen before include "Robinia strangely found in Kenya" , "Badly-behaved child" , "Flat round object" , "African city" , "East African capital" .)
