Drink gets left (4)
I believe the answer is:
port
I believe this is a double definition.
'drink' is the first definition.
(port is a kind of drink)
'left' is the second definition.
(left side of a ship - opposite of starboard)
'gets' acts as a link.
(Other definitions for port that I've seen before include "Wine left at sea ?" , "where one would expect water" , "After-dinner drink" , "Saint John, for one, > left" , "Left, opening, wine" .)
