Understand bishop's responsibility (3)
I believe the answer is:
This clue is a double definition.
'understand' is the first definition.
(I know that understand can be written as see)
'bishop's responsibility' is the second definition.
(jurisdiction of a bishop, eg the Holy See)
(Other definitions for see that I've seen before include "Perceive with eyes or mind" , "make out" , "View; realise" , "Observe the bishop's domain" , "Spot" .)
