Avoid duel, rewriting the end (5)
I believe the answer is:
elude
'avoid' is the definition.
(I know that elude is a more specific form of avoid)
'duel rewriting the end' is the wordplay.
'rewriting' is an anagram indicator.
'end' says to take the final letters.
The last letter of 'the' is 'e'.
'duel' anagrammed gives 'elud'.
'elud'+'e'='ELUDE'
(Other definitions for elude that I've seen before include "Escape from; baffle" , "Avoid (e.g. capture)" , "Dodge, duck" , "Avoid first" , "Evade; baffle" .)
