grenade: [16] The original grenades were small spherical explosive-filled cases with a wick on top. In shape, they bore more than a passing resemblance to pomegranates. The Old French term for ‘pomegranate’ was pome grenate, or just grenate for short, and it was this abbreviated form, altered to grenade under the influence of the related Spanish granada, that was applied to the explosive device. Grenadier [17] came from the French derivative grenadier ‘grenadethrower’. => grain, grenadier, pomegranate[grenade etymology, grenade origin, 英语词源]
