Revitalise Scots town father leaves (5)
I believe the answer is:
renew
'revitalise' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for renew that I've seen before include "Transform born-again" , "make a fresh start" , "Give fresh life to" , "modernise" , "Renovate" .)
