One who gets under your skin at work? (9)
I believe the answer is:
tattooist
'work?' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see an association between them that I don't see?
'one who gets under your skin at' is the wordplay.
I cannot really see how this works, but
'one' could be 'o' (I've seen this in other clues) and 'o' is found in the answer.
'gets' could be 'is' (I've seen this in other clues) and 'is' is located in the answer.
'at' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tattooist that I've seen before include "Skin decorator" , "Sort of marksman" , "Designer" , "Skin artist" , "permanent marker?" .)
