Stop religious type going round bend (6)
I believe the answer is:
desist
'stop' is the definition.
(desist means to stop)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for desist that I've seen before include "Forbear" , "Stop (doing something)" , "Leave off (doing a thing)" , "Stop, whoa, give over" , "Abstain, refrain" .)
