When everybody cheers up? (8,7)
I believe the answer is:
standing ovation
'when everybody' is the definition.
I can't tell whether this defines the answer.
'cheers up?' is the wordplay.
I cannot quite understand how this works, but
'cheers' could be 'ovation' and 'ovation' is located in the answer.
'up?' could be 'standing' (I've seen this before) and 'standing' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for standing ovation that I've seen before include "Applause" , "Rapturous reception" , "warm reception" .)
