Drink other than water (8)
I believe the answer is:
beverage
'drink other than water' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for beverage that I've seen before include "Liquid for drinking" , "such as a Frappuccino" , "Drink other than water" , "Any drink, say a beer" , "Non-alcoholic drink" .)
