Cordial drunk in gale (6)
I believe the answer is:
genial
'cordial' is the definition.
(I know that cordial can be written as genial)
'drunk in gale' is the wordplay.
'drunk' indicates anagramming the letters.
'in'+'gale'='ingale'
'ingale' anagrammed gives 'GENIAL'.
(Other definitions for genial that I've seen before include "Cordial" , "Affable in Ealing" , "Cheerful and well-disposed" , "Mild and pleasant" , "'Affable, warm and friendly (6)'" .)
