Group's reason for not playing badminton? (5)
I believe the answer is:
nonet
'group's' is the definition.
(group of nine musicians)
'reason for not playing badminton?' is the wordplay.
I cannot really see how this works, but
'not' could be 'non' (I've seen this in other clues) and 'non' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nonet that I've seen before include "Multi-figure composition" , "baseball team" , "group composition" , "Band's" , "Work for nine players" .)
