How heat might knock one out? (9)
I believe the answer is:
eliminate
'out?' is the definition.
Although both the answer and definition are verbs in their base form, I cannot understand how one could define the other.
'how heat might knock one' is the wordplay.
I cannot quite see how this works, but
'one' could be 'li' (I've seen this in other clues) and 'li' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for eliminate that I've seen before include "defeat" , "waste" , "Reject" , "Eradicate" , "Annihilate" .)
