Remove errors (5)
I believe the answer is:
emend
'remove errors' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for emend that I've seen before include "Revise (a text) (E, not A)" , "make an improvement" , "Edit, improve" , "would appear better" , "Alter to improve (text)" .)
