Transfer some cash (6)
I believe the answer is:
change
I believe this is a double definition.
'transfer' is the first definition.
(changing is a kind of transfering)
'some cash' is the second definition.
(change is a kind of cash)
(Other definitions for change that I've seen before include "Make or become different" , "They say it's as good as a rest" , "Word for small coins in pocket" , "Alter for small coins" , "Alter, modify" .)
