Royal women in part of New York (6)
I believe the answer is:
queens
'part of new york' is the definition.
(I know that Queens is part of New York City)
'royal women' is the wordplay.
'royal' becomes 'queen' (queen is a kind of royal).
'women' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'queen'+'s'='QUEENS'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for queens that I've seen before include "Borough of NYC for the royals" , "NY borough; two Oxbridge colleges" , "Brooklyn's neighbour" , "Most powerful pieces in chess games" , "Borough of New York City for monarchs" .)
