Lad from Winchester? (3,2,1,3)
I believe the answer is:
son of a gun
'winchester?' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'lad from' is the wordplay.
I cannot really see how this works, but
'lad' could be 'son' and 'son' is located in the answer.
'from' could be 'of' (I've seen this in other clues) and 'of' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for son of a gun that I've seen before include "Rogue (with a shooter for a father?)" , "expression of mild annoyance" , "Rascal" , "Jocular or affectionate term for someone (whose parentage might be in doubt?)" , "Maybe Billy the Kid's issue" .)
