How do we know an asp killed Cleopatra? (5,5)
I believe the answer is:
grass snake
'how do' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
I don't understand the rest of the clue.
Can you help me to learn more?
(Another definition for grass snake that I've seen is " legless wild thing".)
I've seen this clue in the Evening Standard.
Want a hint initially instead of a full solution?
