Turn me over - that's better (7)
I believe the answer is:
emended
'better' is the definition.
Both the answer and definition are adjectives. Perhaps you can see a link between them that I can't see?
'turn me over' is the wordplay.
'turn' shows that the letters should be reversed in order.
'over' becomes 'ended' (over can mean finished or ended).
'me' written backwards gives 'em'.
'em'+'ended'='EMENDED'
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for emended that I've seen before include "Made corrections" , "Made changes to" , "Edited" , "Acted like editors" , "Rectified" .)
