Decorate one way or the other (7)
I believe the answer is:
'decorate' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for repaper that I've seen before include "renew wall-covering" , "Apply new wall covering" , "Decorate walls again" , "Decorate again (palindrome)" , "Cover walls again" .)
