Drink reportedly precedes sound of laughter and excitement (8)
I believe the answer is:
brouhaha
'excitement' is the definition.
(thesaurus)
'drink reportedly precedes sound of laughter' is the wordplay.
I cannot quite see how this works, but
'sound' could be 'haha' (I have seen 'Sound of laughter' mean 'ha-ha' so perhaps 'sound' could also mean 'ha-ha') and 'haha' is found within the answer.
'of' could be 'o' and 'o' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for brouhaha that I've seen before include "Overexcited critical response" , "Outcry" , "'Confused disturbance, uproar (8)'" , "Stir" , "rumpus" .)
