Endless game in which pig may be bought? (4)
I believe the answer is:
poke
'in which pig may be bought?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'endless game' is the wordplay.
I cannot quite understand how this works, but
'game' could be 'p' (I have seen 'French game ' mean 'p' so perhaps 'game' could also mean 'p') and 'p' is found within the answer.
The remaining letters 'oke' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for poke that I've seen before include "Proverbial pig container?" , "Prod with a sharp object" , "Jab or prod" , "Jab (with a finger)" , "Probe with stick" .)
