Quietly rattle broken salver (7)
I believe the answer is:
platter
'salver' is the definition.
(thesaurus)
'quietly rattle broken' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet**).
'broken' is an anagram indicator.
'rattle' is an anagram of 'latter'.
'p'+'latter'='PLATTER'
(Other definitions for platter that I've seen before include "Large flat serving dish" , "Salver" , "Charger" , "Large flat plate" , "Shallow serving dish" .)
