One centre of continental capitalism (5)
I believe the answer is:
paris
'centre of continental capitalism' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'one' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
The remaining letters 'pars' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for paris that I've seen before include "French capital - Trojan prince" , "Eiffel Tower city" , "French department" , "Legendary prince" , "City on the Seine" .)
