Run off and get change for a dinar (5)
I believe the answer is:
drain
'run off' is the definition.
(I've seen this in another clue)
'change for a dinar' is the wordplay.
'change for' indicates an anagram.
'dinar' is an anagram of 'DRAIN'.
'and get' is the link.
(Other definitions for drain that I've seen before include "See 11 dn" , "Siphon off" , "Waste pipe" , "Something using up resources" , "ditch" .)
