Regard for diocese (3)
I believe the answer is:
see
This clue is a double definition.
'regard' is the first definition.
(I know that regard can be written as see)
'diocese' is the second definition.
(I know that see is a type of diocese)
'for' acts as a link.
(Other definitions for see that I've seen before include "make out" , "... have interview with" , "Jurisdiction of a bishop" , "Appreciate" , "around cathedral" .)
