Arts money wasted on building (9)
I believe the answer is:
monastery
'building' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'arts money wasted' is the wordplay.
'wasted' indicates anagramming the letters.
'arts'+'money'='artsmoney'
'artsmoney' anagrammed gives 'MONASTERY'.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for monastery that I've seen before include "One vows to stay here" , "brother's house" , "Community of monks" , "Religious establishment" , "Where brothers gather" .)
