Win, obtain (4)
I believe the answer is:
This clue is a double definition.
'win' is the first definition.
(I know that win can be written as gain)
'obtain' is the second definition.
(I know that gain is a is a more specific form of the action obtain)
(Other definitions for gain that I've seen before include "reward" , "Increase; secure" , "Benefit; put on (weight)" , "Advance" , "Profit; acquire" .)
