"small explosive shell," 1590s, earlier "pomegranate" (1520s), from Middle French grenade "pomegranate" (16c.), earlier grenate (12c.), from Old French pomegrenate (influenced by Spanish granada); so called because the many-seeded fruit suggested the powder-filled, fragmenting bomb, or from similarities of shape. See pomegranate.
