Money to give or use (5)
I believe the answer is:
euros
'money' is the definition.
(I know that Euros is a Currency)
'give or use' is the wordplay.
'give' indicates anagramming the letters (I've seen 'giving' mean this (the letters give the letters for another word)).
'or'+'use'='oruse'
'oruse' with letters rearranged gives 'EUROS'.
'to' is the link.
(Other definitions for euros that I've seen before include "French coins and notes" , "currency in Greece" , "Continental coins" , "Common currency" , "Units of modern European currency" .)
