jacket
UK: ˈdʒækɪt | US: ˈdʒækɪt
n. a short coat, typically extending to the hips or waist
n. an outer covering or casing (e.g., for machinery or books)
The word "jacket" traces back to the Middle French "jaquet," a diminutive of "jaque," referring to a short, lightweight coat worn by peasants. The suffix "-et" (from Old French) adds a diminutive sense, emphasizing its shorter length compared to a full coat. Over time, "jacket" expanded to describe protective coverings (e.g., book jackets), retaining the core idea of a lightweight outer layer.
