Maybe a capital place to raise capital (4)
I believe the answer is:
'capital' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for city that I've seen before include "- of God (St Augustine)" , "Large conurbation" , "Big conurbation" , "Large town" , "See 4" .)
