Word History: The resemblance in form between the words ticket and etiquette is not accidental; both have the same ultimate source, Old French estiquet. But because these words were borrowed into English at different times, they came into our language with different meanings. Old French estiquet meant "a note, label." Having been changed in form to etiquet in French, the word was adopted into English in the 16th century in a form without the initial e, tiket (first recorded in 1528). The earliest uses of the word in English were in the senses "a short written notice," "a notice posted in a public place," and "a written certification." The word is first recorded with reference to something like a ticket of admission in 1673. In French, meanwhile, the word (in the form étiquette) came in the 18th century to mean "a ceremonial, a book in which court ceremonies were noted down or labeled." The French word was borrowed again into English, this time in the form etiquette, which is first recorded in 1750.
