Say, James going round in the buff? (6)
I believe the answer is:
nudist
'say' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'james going round in the buff?' is the wordplay.
'james' becomes 'sid' (I've seen this in other clues).
'going round' shows that the letters should be reversed in order.
'in' is an insertion indicator.
'the buff?' becomes 'nut' (both can mean an enthusiast or fan).
'sid' written backwards gives 'dis'.
'dis' going into 'nut' is 'NUDIST'.
Can you help me to learn more?
(Other definitions for nudist that I've seen before include "who exposes everything!" , "One baring all" , "Person who goes around unclothed" , "Sun worshipper" , "Person who discards clothes by choice" .)
