People likely to have nothing on after work? (9)
I believe the answer is:
naturists
'people' is the definition.
(naturist is a kind of person)
'likely to have nothing on after work?' is the wordplay.
I cannot quite see how this works, but
'on' could be 'at' (I've seen this in other clues) and 'at' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for naturists that I've seen before include "Those going naked" , "Nudists" .)
