Hand over or donate (4)
I believe the answer is:
give
I believe this clue is a double definition.
'hand over' is the first definition.
(I've seen this before)
'donate' is the second definition.
(I know that donate is a more specific form of the action give)
(Other definitions for give that I've seen before include "Contribute - elasticity" , "be generous?" , "Donate or hand over" , "Yield - supply" , "Offer, elasticity" .)
