Rectifies (6)
I believe the answer is:
amends
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">rectifies</span>' is the definition.<br/ ><span class="explanation-format__explanation">('amend' can be a synonym of 'rectify')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for amends that I've seen before include "It is made in reparation" , "They're made to compensate" , "Make these to atone for injuries or loss caused" , "Redress" , "Makes changes, to a text say" .)
