Drunk sounding mean — something in cocktail? (9)
I believe the answer is:
shellfish
'cocktail?' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for shellfish that I've seen before include "paella ingredient" , "Oysters, crabs, shrimps etc" , "provider of pearls?" , "Lobsters, cockles, mussels etc" , "Oysters, cockles, mussels etc" .)
