A nose for tobacco? (5)
I believe the answer is:
snout
This clue is a double definition.
'a nose' is the first definition.
(snout is a kind of nose)
'tobacco?' is the second definition.
(I've seen this before)
'for' acts as a link.
(Other definitions for snout that I've seen before include "Tobacco -- hooter" , "Animal's long, projecting nose" , "Pig's nose" , "Nose; tobacco (slang)" , "nose of pig" .)
