Craig turned into smoker (5)
I believe the answer is:
cigar
'smoker' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'craig turned' is the wordplay.
'turned' indicates an anagram.
'craig' anagrammed gives 'CIGAR'.
'into' is the link.
Can you help me to learn more?
(Other definitions for cigar that I've seen before include "Something to smoke" , "Eg, Havana, panatella" , "Item for smoking" , "Item kept in a humidor" , "Rolled tobacco leaf for smoking" .)
