What does tornado mean?
A tornado is a violently rotating column of air that forms beneath a thunderstorm and may extend toward the ground. Not every funnel-shaped cloud becomes a tornado, and a tornado does not always touch the surface, but one that does can bring powerful winds, flying debris, sudden pressure changes, and severe damage along its path. Tornadoes can occur on several continents, although they are especially frequent in the central United States. The word is also used figuratively for an overwhelming rush of movement, disorder, or change, as in “a tornado of activity.” It comes from Spanish, where it originally conveyed the idea of something “turned.” The modern meteorological meaning grew out of earlier English descriptions of twisting winds and waterspouts. As a common English word, tornado combines a precise scientific meaning with a vivid figurative sense of violent, disorienting motion.

Etymology of tornado
English borrowed tornado from Spanish, in which the word means “turned” and is associated with the verb tornarse, “to turn.” That Romance verb ultimately traces to Latin tornare, the root also behind cognates such as tournament and tourniquet. Early English uses could refer to twisting storms or waterspouts, while the established modern meteorological sense developed as the nature of these storms became better understood.
