A game vegetable? (6)
I believe the answer is:
squash
This clue is a double definition.
'a game' is the first definition.
(squash is a kind of game)
'vegetable?' is the second definition.
(I know that squash is a type of vegetable)
(Other definitions for squash that I've seen before include "A sport; a drink; a veg" , "Indoor racquet game" , "court action" , "Cordial drink" , "Ball game; gourd" .)
