The capital of the Netherlands (9)
I believe the answer is:
amsterdam
'the capital of the netherlands' is the definition.
('Amsterdam' can be a synonym of 'capital of the netherlands')
This is the entire clue.
(Other definitions for amsterdam that I've seen before include "City known for canals" , "City of the Rijks-museum and Van Gogh Museum" , "Dutch city of canals" , "city with many canals" , "Dutch port" .)
