Etymology
Origin of torpedo
1510–20; < Latin torpēdō numbness, torpidity, electric ray, equivalent to torpē ( re ) to be stiff ( see torpid 1) + -dō noun suffix
Explanation
A torpedo is a type of missile or bomb fired underwater. To torpedo is to attack with torpedoes. Torpedoes are cigar-shaped projectiles that are used to attack other submarines or boats. The word torpedo comes from the name of a kind of electric ray that numbs you with its sting (torpediniformes). Torpedoes can also be used to attack a target on land. When a submarine fires torpedoes, they're torpedoing the target. Torpedoes explode upon impact, and they're very powerful weapons.
