Continental capitalists can congregate here (5)
I believe the answer is:
paris
'continental capitalists can congregate here' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
This is the entire clue.
Can you help me to learn more?
(Other definitions for paris that I've seen before include "where plaster comes from?" , "I spar (anag)" , "Arc de Triomphe city" , "English chronicler" , "French department" .)
