Can of drink? (4)
I believe the answer is:
brig
This clue could be a double definition.
'can' is the first definition.
(thesaurus)
'drink?' is the second definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'of' is the link.
Can you help me to learn more?
(Other definitions for brig that I've seen before include "officer contracted" , "Two-masted square-rigger" , "Two-master; army officer (abbr.)" , "Two-masted square-rigged vessel" , "Two-masted square rigger" .)
