Joe North’s drink (3)
I believe the answer is:
gin
'drink' is the definition.
(gin is a kind of drink)
'joe north's' is the wordplay.
'joe' becomes 'gi' (GI Joe).
'north' becomes 'n' ('N' can be a synonym of 'north').
'gi'+'n'='GIN'
(Other definitions for gin that I've seen before include "Alcoholic drink made from juniper berries - it's a trap" , "Spirit; cotton machine" , "Trap for catching animals" , "Trap for snaring small mammals" , "Spirit; trap" .)
