Revive, repeat (5)
I believe the answer is:
renew
I believe this is a double definition.
'revive' is the first definition.
(I know that revive is a more specific form of the action regenerate)
'repeat' is the second definition.
(thesaurus)
(Other definitions for renew that I've seen before include "modernise" , "Repeat for next year" , "Restore (worn out item)" , "Replace" , "Renovate" .)
