Does one concur with Nick? (8)
I believe the answer is:
satanist
'nick?' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I don't see?
'does one concur' is the wordplay.
I cannot quite see how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is located in the answer.
This explanation may well be incorrect...
'with' is the link.
Can you help me to learn more?
(Other definitions for satanist that I've seen before include "A follower of the devil" , "Devil-worshipper" , "One who worships the devil" , "Devil devotee" , "diabolical fellow" .)
