Suave; courteous (8)
I believe the answer is:
debonair
This clue is a double definition.
'suave' is the first definition.
(I know that suave can be written as debonair)
'courteous' is the second definition.
(thesaurus)
(Other definitions for debonair that I've seen before include "Suave and urbane on air bed" , "Of good appearance and manners" , "Jaunty, charming" , "Cheerful, charming and elegant" , "Jaunty and sophisticated" .)
