South African capital (8)
I believe the answer is:
pretoria
'south african capital' is the definition.
(administrative capital of South Africa)
This is the entire clue.
(Other definitions for pretoria that I've seen before include "City in South Africa" , "A ripe rot in S. Africa" , "Pirate or a South African city, strangely" , "Administrative capital of South Africa" , "Administrative capital of South African" .)
