Clergyman loses one of his buildings (7)
I believe the answer is:
minster
'clergyman' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for minster that I've seen before include "Clergyman" , "Abbey or priory church" , "Large important church" , "Old monastic cathedral, such as York's" , "Large church (or cathedral at York)" .)
