Repeat cure afresh and get better (10)
I believe the answer is:
recuperate
'get better' is the definition.
(synonyms)
'repeat cure afresh' is the wordplay.
'afresh' indicates anagramming the letters.
'repeat'+'cure'='repeatcure'
'repeatcure' anagrammed gives 'RECUPERATE'.
'and' is the link.
(Other definitions for recuperate that I've seen before include "Get better" , "Convalesce" , "Rally, recover" , "Recover from an illness" .)
