Definition of wind up

The phrase "wind up" originated in the 17th century, likely stemming from the action of winding a clock or other mechanical device. The act of turning a crank or key to tighten a spring was described as "winding up." This sense of "winding up" evolved to encompass the idea of preparing something for action or excitement. By the 19th century, it was used figuratively to describe the act of teasing or provoking someone, likely referencing the way a wound-up clock builds tension before it strikes.
