Provided with food taken back to consume — best or worst (6)
I believe the answer is:
defeat
'best or worst' is the definition.
(I've seen this in another clue)
'provided with food taken back to consume' is the wordplay.
I cannot really understand how this works, but
'food' could be 'e' (E is an example) and 'e' is located in the answer.
'consume' could be 'eat' (eating is a kind of consuming) and 'eat' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for defeat that I've seen before include "Gain victory over" , "best or worst" , "Get the better of" , "Conquest" , "Win over, frustrate" .)
