Dispose of ale in time, drunk (9)
I believe the answer is:
eliminate
'dispose of' is the definition.
(thesaurus)
'ale in time drunk' is the wordplay.
'drunk' indicates an anagram.
'ale'+'in'+'time'='aleintime'
'aleintime' is an anagram of 'ELIMINATE'.
(Other definitions for eliminate that I've seen before include "Cut out" , "Murder" , "Discard - exclude" , "Exclude from further stage of competition" , "Eradicate" .)
