Dish quietly departed (5)
I believe the answer is:
plate
'dish' is the definition.
(plate is a kind of dish)
'quietly departed' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'departed' becomes 'late' (I've seen this before).
'p'+'late'='PLATE'
(Other definitions for plate that I've seen before include "Leapt (anag.)" , "Item of crockery" , "impression" , "Shallow vessel" , "Coat with metal" .)
