Report naughty nun at once when cuddling fellows (12)
I believe the answer is:
announcement
'report' is the definition.
(I've seen this before)
'naughty nun at once when cuddling fellows' is the wordplay.
I cannot really see how this works, but
'when' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
'fellows' could be 'men' (fellow can mean a man) and 'men' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for announcement that I've seen before include "A public statement" , "Public declaration" , "Proclamation" , "Statement, declaration" , "Public notice" .)
