Craig turned into a smoker (5)
I believe the answer is:
'a smoker' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'craig turned' is the wordplay.
'turned' indicates anagramming the letters.
'craig' is an anagram of 'CIGAR'.
'into' acts as a link.
Can you help me to learn more?
(Other definitions for cigar that I've seen before include "Cylinder of tobacco" , "Havana, perhaps" , "Close, but no ___ !" , "Big roll of tobacco" , "Corona, eg" .)
