Smoky city? (6)
I believe the answer is:
havana
'city?' is the definition.
(Havana is an example)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for havana that I've seen before include "Cuban capital - cigar" , "Cuba's capital" , "city" , "Smoke" , "Fine cigar" .)
