Replace or restore (5)
I believe the answer is:
renew
I believe this is a double definition.
'replace' is the first definition.
(I've seen this before)
'restore' is the second definition.
(I know that renew is a type of restore)
(Other definitions for renew that I've seen before include "Replace" , "Reform" , "Take up again" , "Restore - recommence" , "Transform born-again" .)
