Cleric loses one of his buildings (7)
I believe the answer is:
minster
'cleric loses one of his buildings' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for minster that I've seen before include "Abbey or priory church" , "Large important church" , "Large church (eg, York)" , "Old monastic cathedral, such as York's" , "Large church (or cathedral at York)" .)
