overturn
UK: ˌəʊvəˈtɜːn | US: ˌoʊvərˈtɜːrn
vt. to turn something over or upside down
vt. to reverse a decision, law, or situation
vi. to capsize or tip over
The word "overturn" combines "over," from Old English "ofer" (meaning "above" or "beyond"), and "turn," from Old English "tyrnan" (meaning "to rotate" or "change direction"). The fusion reflects a literal or figurative action of turning something beyond its original position or state. Historically, it evolved from physical actions (e.g., flipping an object) to abstract reversals (e.g., legal decisions).
