After such a good time, are repairs necessary? (7)
I believe the answer is:
ripping
'time are repairs necessary?' is the definition.
I can't judge whether this defines the answer.
'after such a good' is the wordplay.
I cannot really see how this works, but
'good' could be 'pi' (I've seen this in other clues) and 'pi' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ripping that I've seen before include "Tearing forcefully" , "producing tears?" , "Tearing - splendid!" , "Excellent; tearing" , "Knockout" .)
