Hand over change (8)
I believe the answer is:
transfer
I believe this is a double definition.
'hand over' is the first definition.
(thesaurus)
'change' is the second definition.
(transfer is a kind of change)
(Other definitions for transfer that I've seen before include "Reassign" , "Hand, move, change, over" , "Extremely stiff in coach, I must leave conveyance" , "Change to another group or surface" , "Change (from one thing to another)" .)
