Priest's circle dispersed (6)
I believe the answer is:
cleric
'priest's' is the definition.
(I've seen this in another clue)
'circle dispersed' is the wordplay.
'dispersed' indicates anagramming the letters.
'circle' is an anagram of 'CLERIC'.
(Other definitions for cleric that I've seen before include "Priest caught in circle" , "One ordained" , "Person in holy orders" , "One who takes orders" , "One is in religious orders" .)
