Dim sun when out will hardly encourage it (6)
I believe the answer is:
nudism
'will hardly encourage it' is the definition.
I can't tell whether this defines the answer.
'dim sun when out' is the wordplay.
'when out' is an anagram indicator (out can mean incorrect or inaccurate).
'dim'+'sun'='dimsun'
'dimsun' is an anagram of 'NUDISM'.
Can you help me to learn more?
(Other definitions for nudism that I've seen before include "Going without clothes, socially" , "Mind us (anag)" , "Naturism" , "Public exposure" , "Practice of living as nature intended" .)
