A hand grenade is a small hand-held anti-personnel weapon designed to be thrown and then explode after a short time. The word "grenade" is derived from the French grenade, meaning pomegranate, so named because its shrapnel pellets reminded soldiers of the seeds of this fruit. Grenadiers were originally soldiers who specialized in throwing grenades.
