Residents in very louvred part of New York (6)
I believe the answer is:
queens
'part of new york' is the definition.
(I know that Queens part of New York City)
I cannot understand how the rest of the clue works.
(Other definitions for queens that I've seen before include "Borough of New York City for monarchs" , "[COLLEGE] < Tennis club" , "Borough of NYC for the royals" , "Most powerful pieces in chess games" , "powerful men on board" .)
