Alcoholic tipple left (4)
I believe the answer is:
port
This might be a double definition.
'alcoholic tipple' is the first definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'left' is the second definition.
(left side of a ship - opposite of starboard)
Can you help me to learn more?
(Other definitions for port that I've seen before include "After-dinner drink" , "Opposite of starboard" , "Dessert wine" , "'Any . . . . In a storm'" , "Anchorage" .)
