Study opening in religious community (7)
I believe the answer is:
convent
'religious community' is the definition.
(I've seen this before)
'study opening' is the wordplay.
'study' becomes 'con' (I've seen this before).
'opening' becomes 'vent' (vent is a kind of opening).
'con'+'vent'='CONVENT'
'in' acts as a link.
(Other definitions for convent that I've seen before include "Community of nuns" , "Building for prayer" , "Religious community" , "place for nuns" , "Nunnery" .)
