Supply ale or gin in local (8)
I believe the answer is:
regional
'local' is the definition.
(in a particular region)
'supply ale or gin' is the wordplay.
'supply' indicates anagramming the letters (in a supple way).
'ale'+'or'+'gin'='aleorgin'
'aleorgin' is an anagram of 'REGIONAL'.
'in' is the link.
(Other definitions for regional that I've seen before include "of the district" , "From a geographical area" , "Relating to local area" , "Territorial" , "Relating to a specific area of the country" .)
