[ F., fr. LL. torsio, fr. L. torquere, tortum, to twist. See { Torture}.] 1. The act of turning or twisting, or the state of being twisted; the twisting or wrenching of a body by the exertion of a lateral force tending to turn one end or part of it about a longitudinal axis, while the other is held fast or turned in the opposite direction.
