I trust an eccentric, one espousing nudity (8)
I believe the answer is:
naturist
'nudity' is the definition.
(thesaurus)
'i trust an eccentric' is the wordplay.
'eccentric' indicates an anagram.
'i'+'trust'+'an'='itrustan'
'itrustan' with letters rearranged gives 'NATURIST'.
'one espousing' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for naturist that I've seen before include "Person who goes naked in designated areas" , "One practising nudism for reasons of health or religion" , "One who goes naked" , "Truant is apt to be a nudist" , "Person who practices nudity" .)
