Bomb Definition - "a container filled with explosive or incendiary material, designed to explode on impact or when detonated by a timing, proximity, or remote-control device."

From wiki -''The word "grenade" derives from the French word for a "small explosive shell". Its first usage in English dates from the 1590s. It is likely derived from Old French pomegranate (influenced by Spanish granada), so called because the many-seeded fruit suggested the powder-filled, fragmenting bomb, or from similarity of shape.''
