The trap of strong drink (3)
I believe the answer is:
gin
I believe this is a double definition.
'the trap' is the first definition.
(gin trap is a kind of animal trap)
'strong drink' is the second definition.
(gin is a kind of strong drink)
'of' acts as a link.
(Other definitions for gin that I've seen before include "Animal trap or alcoholic drink" , "Alcohol for the snare" , "It often gets mixed up with this" , "It could be used for drinking" , "Colourless spirit flavoured with juniper berries - mother's ruin" .)
