- etiquette
- 1750, from Fr. étiquette "prescribed behavior," from O.Fr. estiquette "label, ticket." The sense development in Fr. is from small cards written or printed with instructions for how to behave properly at court (cf. It. etichetta, Sp. etiqueta), and/or from behavior instructions written on a soldier's billet for lodgings (the main sense of the O.Fr. word).
