Wrecked silver drink set (7)
I believe the answer is:
aground
'wrecked' is the definition.
(thesaurus)
'silver drink set' is the wordplay.
I cannot really see how this works, but
'silver' could be 'ag' (Ag is the chemical symbol for silver) and 'ag' is present in the answer.
'set' could be 'round' (I have seen 'Set of holes' mean 'round' so perhaps 'set' could also mean 'round') and 'round' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for aground that I've seen before include "(Of ship) touching the bottom" , "Like a stranded ship" , "Unable to move" , "on rocks, perhaps" , "out of water" .)
