Community centre for retired ladies (7)
I believe the answer is:
nunnery
'community centre' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for nunnery that I've seen before include "Religious establishment" , "Hamlet to Ophelia: 'Get thee to a . . . . . . .'" , "Religious house for females" , "sisters' place" , "Female religious house" .)
