Make good rum — and beer is drunk (9)
I believe the answer is:
reimburse
'make good' is the definition.
(thesaurus)
'rum and beer is drunk' is the wordplay.
'and' says to put letters next to each other.
'drunk' indicates anagramming the letters.
'beer'+'is'='beeris'
'rum' put after 'beeris' is 'beerisrum'.
'beerisrum' is an anagram of 'REIMBURSE'.
(Other definitions for reimburse that I've seen before include "Pay back (e.g. expenses)" , "Repay a person who has spent or lost money" , "refund" , "Repay (a sum of money)" , "Financially compensate" .)
