Minister’s peculiar circle (6)
I believe the answer is:
cleric
'minister's' is the definition.
(thesaurus)
'peculiar circle' is the wordplay.
'peculiar' indicates an anagram (I've seen this in other clues).
'circle' is an anagram of 'CLERIC'.
(Other definitions for cleric that I've seen before include "Ordained minister" , "Religious official" , "Churchman" , "Religious man" , "Divine" .)
