Clergyman going round in circle (6)
I believe the answer is:
cleric
'clergyman' is the definition.
(I know that clergyman can be written as cleric)
'going round in circle' is the wordplay.
'going round in' indicates anagramming the letters.
'circle' is an anagram of 'CLERIC'.
(Other definitions for cleric that I've seen before include "Person in holy orders" , "Church official" , "One is in religious orders" , "Divine" , "Person ordained to the Christian ministry" .)
