Venue contains quiet ill-will (5)
I believe the answer is:
spite
'ill-will' is the definition.
(thesaurus)
'venue contains quiet' is the wordplay.
'venue' becomes 'site' (I've seen this in another clue).
'contains' indicates putting letters inside.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'site' going around 'p' is 'SPITE'.
(Other definitions for spite that I've seen before include "Hatred" , "Desire to hurt or annoy" , "Desire to intentionally and maliciously hurt or offend" , "animosity" , "Malicious desire to hurt or humiliate" .)
