Capital to repair damage (8)
I believe the answer is:
pretoria
'capital' is the definition.
(administrative capital of South Africa)
'to repair damage' is the wordplay.
'damage' indicates anagramming the letters (I've seen 'damaged' mean this).
'to'+'repair'='torepair'
'torepair' anagrammed gives 'PRETORIA'.
(Other definitions for pretoria that I've seen before include "Pirate or a South African city, strangely" , "A ripe rot in S. Africa" , "City in South Africa" , "Administrative capital of South Africa" , "Pirate or, oddly, a South African city" .)
