Cigar smell (5)
I believe the answer is:
whiff
This could be a double definition.
'cigar' is the first definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'smell' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for whiff that I've seen before include "Scent in the air?" , "Brief or faint smell" , "Passing smell" , "draught" , "Suspicion" .)
