Highball on the snooker table? (5)
I believe the answer is:
black
'highball on the snooker table?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for black that I've seen before include "second player on board" , "Like clubs and spades" , "Without light" , "bar" , "Colour of jet" .)
