Alter money coming back? (6)
I believe the answer is:
change
This clue is a triple definition!
'alter' is the first definition.
(I know that alter is a more specific form of alter)
'money' is the second definition.
(I've seen this in other clues)
'coming' acts as a link.
'back?' is the third definition.

(Other definitions for change that I've seen before include "They say it's as good as a rest" , "Alter for small coins" , "Alter the money returned" , "Word for small coins in pocket" , "Cash" .)
