etiquette

Origin

1740, from French étiquette (“property, a little piece of paper, or a mark or title, affixed to a bag or bundle, expressing its contents, a label, ticket”), from Middle French estiquette (“ticket, memorandum”), from the Old French verb estechier, estichier, estequier (“to attach, stick”), (compare Picard estiquier (“to stick, pierce”)), from Frankish *stekan, *stikkjan (“to stick, pierce, sting”), from Proto-Germanic *stikaną, *stikōną, *staikijaną (“to be sharp, pierce, prick”), from Proto-Indo-European *(s)teyg- (“to be sharp, to stab”). Akin to Old High German stehhan (“to stick, attach, nail”) (German stechen (“to stick”)), Old English stician (“to pierce, stab, be fastened”).
