Board given nothing to replace a cheap bottle (5)
I believe the answer is:
plonk
'board' is the definition.
The definition and answer 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?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for plonk that I've seen before include "Wine - put down with a thud" , "cheap drink" , "Put down - cheap wine" , "Cheap red or white" , "Drop" .)
