He takes orders to break the circle (6)
I believe the answer is:
cleric
'he takes orders' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'break the circle' is the wordplay.
'break' indicates anagramming the letters.
'circle' is an anagram of 'CLERIC'.
'to' is the link.
Can you help me to learn more?
(Other definitions for cleric that I've seen before include "Church official" , "One in holy orders" , "Churchman" , "Religious official" , "Man of the cloth" .)
