To do with the origins of the money (9)
I believe the answer is:
resources
'the money' is the definition.
(thesaurus)
'to do with the origins' is the wordplay.
'to do with' becomes 're' (regarding).
'the origins' becomes 'sources' ('source' can be a synonym of 'origin').
're'+'sources'='RESOURCES'
'of' acts as a link.
(Other definitions for resources that I've seen before include "Personal attributes" , "Available reserve supplies" , "Teaching materials" , "country's means of defence" , "funds" .)
