Renew; give back (7)
I believe the answer is:
restore
I believe this clue is a double definition.
'renew' is the first definition.
(restoring is a kind of renewing)
'give back' is the second definition.

(Other definitions for restore that I've seen before include "Return to original condition" , "Cure" , "Bring back; renovate" , "Repair, put back" , "Build up again" .)
