History
Etymology
* Borrowed from Latin torpēdō (“a torpedo fish; numbness, torpidity, electric ray”), from torpeō (“to be stiff, numb, torpid; to be astounded; to be inactive”) + -ēdō (noun suffix), from Proto-Indo-European *ster- (“stiff”). In the military sense coined by Robert Fulton in 1805. Cognate with Old English steorfan (“to die”), Ancient Greek στερεός (stereós, “solid”), Lithuanian tirpstu (“to become rigid”), Old Church Slavonic трупети (trupeti). * (type of car): From 1908, after "the Torpedo", a car designed by Captain Theo Masui.
