Did you know?

Calling someone debonair is another way of saying they’ve got a certain je ne sais quoi, or to be more specific (and complete the rhyme): savoir faire. Ooh la la! If this all sounds ultra chic to you, you’re not alone. French has a certain cachet, a fanciness and prestige owing in part to its deep etymological, historical, and political connections with English. This extends to many French words that English has borrowed outright or adapted, including debonair. In Anglo-French, someone who was genteel and thought to be well-brought-up was described as deboneire—literally “of good family or nature” (from the three-word phrase de bon aire). When the word was borrowed into English in the 13th century, it basically meant “courteous,” but today’s debonair incorporates suaveness, nonchalance, and maybe even a soupçon of esprit (carefree sophistication with a dash of wit).

Synonyms
