Makes changes to repairs on article (6)
I believe the answer is:
amends
'makes changes to' is the definition.
(I've seen this before)
'repairs on article' is the wordplay.
'repairs' becomes 'mends' ('mend' can be a synonym of 'repair').
'on' is a charade indicator (letters next to each other).
'article' becomes 'a' (indefinite article).
'mends' after 'a' is 'AMENDS'.
(Other definitions for amends that I've seen before include "Makes changes, to a text say" , "Make these to make up for past wrongs" , "Makes minor improvements" , "Compensation" , "Make them to compensate" .)
