Take out a timeline for correction (9)
I believe the answer is:
eliminate
'take out' is the definition.
(I've seen this in another clue)
'a timeline for correction' is the wordplay.
'for correction' indicates anagramming the letters (I've seen this in other clues).
'a'+'timeline'='atimeline'
'atimeline' is an anagram of 'ELIMINATE'.
(Other definitions for eliminate that I've seen before include "Wipe out" , "Do away with, remove" , "Murder" , "Knock out" , "waste" .)
