debonair

Etymology and origin of the English word debonair

History

Pronunciation

  • IPA: /ˌdɛbəˈnɛɹ/; /ˌdɛbəˈneə(ɹ)/ (UK)[1]

Etymology

It is inherited from Middle English debonere (“gracious, kindly”),[2][3][4] borrowed from Old French debonaire,[2][5][6][4] from the phrase de bon aire “of good lineage or disposition”.[2][5][3][4] This combines de “of”, bon “good” and aire “nest, family”, as in aerie.[2] Etymonline suggests that aire may come from Latin ager “field”, in the sense “place of origin”.[6] Merriam-Webster gives the immediate source as Anglo-French deboneire.[3]

Earliest recorded meaning

Gentle, gracious, kind and courteous.[6][7][3] The French phrase was first used of hawks, meaning “thoroughbred”.[6]

Semantic evolution

The Middle English sense of a docile, courteous disposition became obsolete,[6][7] and the word was revived in the 1680s with the altered sense “pleasantly light-hearted and affable”.[6] Today it means suave and urbane, or carefree and jaunty.[2][3][4]
