. Word History: A giant strutting bird leading a cheer at the homecoming game may seem a far cry from a witch fashioning a charm or spell, but these two figures are related historically in the development of the word mascot. Mascot came into English as a borrowing of the French word mascotte, meaning “mascot, charm.” The English word is first recorded in 1881 shortly after the French word, itself first recorded in 1867, was popularized by the opera La Mascotte, performed in December 1880. The French word in turn came from the Provençal word mascoto, “piece of witchcraft, charm, amulet,” a feminine diminutive of masco, “witch.” This word can probably be traced back to Medieval Latin masca, “witch, specter.” Thus for all their apparent differences, yesterday's witches and today's cuddly mascots can be seen in the same light, as agents working their respective magic to bring about a desired outcome.Learn more about mascot
