Platform for quiet disgust (6)
I believe the answer is:
podium
'platform' is the definition.
(podium is a kind of platform)
'quiet disgust' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'disgust' becomes 'odium' (I've seen this before).
'p'+'odium'='PODIUM'
'for' is the link.
(Other definitions for podium that I've seen before include "Soapbox" , "Position of speaker" , "Platform for speaking from" , "Small platform for speaker" , "Stage" .)
