Run off and get change for a dinar (5)
I believe the answer is:
drain
'run' is the definition.
(draining is a kind of running)
'off and get change for a dinar' is the wordplay.
'dinar' can be anagrammed to 'DRAIN'.
But, I am not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for drain that I've seen before include "See 11 dn" , "Siphon off" , "Waste pipe" , "Something using up resources" , "ditch" .)
