It makes a change (9)

I believe the answer is:

amendment

I'm a little stuck... Click here to teach me more about this clue!

'a change' is the definition.
(amendment is a kind of change)

I don't understand how the remainder of the clue works.

(Other definitions for amendment that I've seen before include "Minor improvement" , "maybe fifth taken by US criminal" , "change for the better" , "A qualification" , "Change designed to improve a text" .)

I've seen this clue in The Globe and Mail.
