Difficult chore to turn around smoker (7)
I believe the answer is:
cheroot
'smoker' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'difficult chore to turn' is the wordplay.
'difficult' indicates anagramming the letters.
'turn' says the letters should be written in reverse.
'to' written backwards gives 'ot'.
'chore' is an anagram of 'chero'.
'chero'+'ot'='CHEROOT'
'around' is the link.
Can you help me to learn more?
(Other definitions for cheroot that I've seen before include "Square-cut cigar" , "'Cigar, square at both ends (7)'" , "With both ends cut off squarely, is smoked" , "One smoked" , "Variety of cigar" .)
