Drink squash (6)
I believe the answer is:
scotch
This clue could be a double definition.
'drink' is the first definition.
(Scotch is an example)
'squash' is the second definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for scotch that I've seen before include "A short" , "Put a stop to - whisky" , "dish" , "Put the lid on" , "Put an end to - in Glasgow? (6)" .)
