Fellow with nothing relaxes in wooded areas (7)
I believe the answer is:
forests
'wooded areas' is the definition.
(I've seen this in another clue)
'fellow with nothing relaxes' is the wordplay.
'fellow' becomes 'f' (abbreviation - of a society etc.).
'with' means one lot of letters go next to another.
'nothing' becomes 'o' (O resembles 0).
'relaxes' becomes 'rests' (I've seen this in another clue).
'f'+'o'+'rests'='FORESTS'
'in' acts as a link.
(Other definitions for forests that I've seen before include "Large, densely-wooded area" , "Densely wooded areas" , "Large woods" , "Woodlands" .)
