Correct result captivates this writer (5)
I believe the answer is:
emend
'correct' is the definition.
(thesaurus)
'result captivates this writer' is the wordplay.
'result' becomes 'end' (I've seen this before).
'captivates' is an insertion indicator.
'this writer' becomes 'me' (the person who is writing these clues).
'end' going around 'me' is 'EMEND'.
(Other definitions for emend that I've seen before include "Remove faults from" , "Polish" , "Edit; make alterations to a draft" , "Improve by editing" , "Edit, improve" .)
