The capital of Ethiopia (5,5)
I believe the answer is:
addis ababa
'the capital of ethiopia' is the definition.
('Addis Ababa' can be a synonym of 'capital of ethiopia')
This is the entire clue.
(Other definitions for addis ababa that I've seen before include "African capital" , "Ethiopia's capital" , "Unaccompanied" , "African city" , "Capital of Ethiopia" .)
