Correct; change (5)
I believe the answer is:
amend
I believe this is a double definition.
'correct' is the first definition.
(amending is a kind of correcting)
'change' is the second definition.
(amending is a kind of changing)
(Other definitions for amend that I've seen before include "Make minor improvements to (a document)" , "Modify, correct" , "Put right" , "Corrct error, make a minor aleration" , "Change for the better" .)
