On farm one might find this small drink (5)
I believe the answer is:
swine
'on farm one might find' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'small drink' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'drink' becomes 'wine' (wine is an alcoholic drink).
's'+'wine'='SWINE'
'this' is the link.
Can you help me to learn more?
(Other definitions for swine that I've seen before include "cad" , "Nasty people" , "Archaic pigs, Gadarene in Bible" , "See 9" , "Rotter" .)
