Convent (7)
I believe the answer is:
nunnery
'convent' is the definition.
(nunnery is a kind of convent)
This is the entire clue.
(Other definitions for nunnery that I've seen before include "Female religious house" , "Religious establishment" , "Convent" , "sisters' place" , "Hamlet to Ophelia: 'Get thee to a . . . . . . .'" .)
