A superior crowd's din? (6)
I believe the answer is:
uproar
'a superior crowd's din?' is the definition.
'uproar' can be an answer for 'din?' (I've seen this in another clue). I am not certain of the 'a superior crowd's' bit.
'crowd's din?' is the wordplay.
'crowd's' becomes 'up' (I am not sure about this - if you are sure you should believe this answer much more).
'din?' becomes 'roar' (I've seen this in another clue).
'up'+'roar'='UPROAR'
Can you help me to learn more?
(Other definitions for uproar that I've seen before include "Tumult, commotion" , "Tumult, noisy ruckus" , "Outbreak of noisy and boisterous behaviour" , "Lots of angry noise" , "Tumult, chaos" .)
