Get a reduced alcoholic drink (3)
I believe the answer is:
win
'get' is the definition.
(winning is a kind of getting)
'a reduced alcoholic drink' is the wordplay.
'a reduced' means to remove the last letter.
'alcoholic drink' becomes 'wine' (I've seen this before).
'wine' with its last letter taken away is 'WIN'.
(Other definitions for win that I've seen before include "Finish in first place" , "Come first" , "Come out on top" , "Succeed, conquer" , "Trumph" .)
