Offer for money (8)
I believe the answer is:
propound
'offer' is the definition.
(thesaurus)
'for money' is the wordplay.
'for' becomes 'pro' (as in being 'pro' something).
'money' becomes 'pound' (I've seen this in other clues).
'pro'+'pound'='PROPOUND'
(Other definitions for propound that I've seen before include "Put forward an idea for consideration" , "Suggest for consideration" , "Offer for consideration" , "Argue for (idea)" , "Advance" .)
