Cordial spilt in gale (6)
I believe the answer is:
genial
'cordial' is the definition.
(synonyms)
'spilt in gale' is the wordplay.
'spilt' indicates anagramming the letters.
'in'+'gale'='ingale'
'ingale' with letters rearranged gives 'GENIAL'.
(Other definitions for genial that I've seen before include "Friendly and agreeable" , "Cheerful and easy-going" , "relating to the chin" , "Pleasant and cheerful like good host" , "Cheerfully extrovert" .)
