Gracious (5)
I believe the answer is:
suave
'gracious' is the definition.
(thesaurus)
This is the entire clue.
(Other definitions for suave that I've seen before include "Charming and sophisticated though insincere" , "Smooth-mannered and sophisticated" , "Urbane and sophisticated" , "Charming, confident" , "Superficially polite" .)
