Cathedral cleric, second one dismissed (7)
I believe the answer is:
'cathedral' is the definition.
(I know that minster is a type of cathedral)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for minster that I've seen before include "Large church (eg, York)" , "Clergyman" , "Large important church" , "Abbey or priory church" , "Large church (or cathedral at York)" .)
