Shape confusing cleric (6)
I believe the answer is:
circle
'shape' is the definition.
(I know that circle is a type of shape)
'confusing cleric' is the wordplay.
'confusing' indicates an anagram.
'cleric' with letters rearranged gives 'CIRCLE'.
(Other definitions for circle that I've seen before include "Group with shared profession or acquaintances" , "Orbit" , "Go round -- social group" , "Group; move round" , "Section of theatre; group of friends" .)
