Etymology

Origin of unicorn

First recorded in 1200–1250; Middle English, from Old French unicorne, from the Latin adjective ūnicornis “one-horned” (used as a noun in the Vulgate and possibly referring to the rhinoceros), a loan translation from the Greek noun and adjective monókerōs, equivalent to uni- “one” + corn(ū) “horn” + -is adjective suffix; see uni-, horn

Explanation

A unicorn is a mythical horse-like creature which has one horn on its forehead. During the Middle Ages, a unicorn horn was said to have magical healing properties. Unicorns show up in many cultures' traditions of folklore and mythology, reaching as far back as Bronze Age civilizations and ancient Greece. Usually, unicorns are presented in art and stories as looking just like horses — or sometimes goats — aside from their long, spiraling horn. The root of the word unicorn is the Latin adjective unicornis, "having one horn," from uni, or "one," and cornus, "horn."
