Plonk! Put down for discussion and heard complaint (5,4)
I believe the answer is:
table wine
'plonk' is the definition.
(I've seen this before)
'put down for discussion and heard complaint' is the wordplay.
'put down for discussion' becomes 'table' (**).
'and' is a charade indicator (letters next to each other).
'heard' indicates a 'sounds like' (homophone) clue.
'complaint' becomes 'whine' (whine is a kind of complaint).
'whine' is a homophone of 'wine'.
'table'+'wine'='TABLE WINE'
(Other definitions for table wine that I've seen before include "Drink with meals" , "Plonk" , "Drink with meal" .)
