Etymology

The word "tumbling" derives from the Middle English "tumblen," which originally meant "to dance or perform acrobatics," influenced by Old French "tomber" (to fall). The root "tumble" reflects the motion of falling or rolling, while the suffix "-ing" turns it into a noun or adjective describing the action. Over time, "tumbling" became associated with gymnastic movements and uncontrolled falling, retaining its core idea of dynamic, rolling motion.
