Sociable, merry (9)
I believe the answer is:
convivial
This clue is a double definition.
'sociable' is the first definition.
(similar in meaning)
'merry' is the second definition.
(thesaurus)
(Other definitions for convivial that I've seen before include "Welcoming" , "Cheerful, sociable" , "full of cheer" , "Getting on" , "Sociable and lively" .)
