Etymology

Derived from Latin unicornis (uni- "one" + cornu "horn"), reflecting the creature’s defining feature. The term entered Old French as unicorne before being adopted into Middle English. The morpheme uni- (from Latin unus) is widely used in English (e.g., universe, uniform), while corn (from Latin cornu) appears in words like cornet and cornea. The word’s literal meaning ("one-horned") has persisted, but it also symbolizes rarity or purity in modern usage.
