Charming, elegant (5)
I believe the answer is:
suave
This clue is a double definition.
'charming' is the first definition.
(I've seen this in another clue)
'elegant' is the second definition.
(thesaurus)
(Other definitions for suave that I've seen before include "Debonair" , "Charming, elegant" , "Charming and sophisticated though insincere" , "Superficially polite" , "Smooth-tongued" .)
