trapeze (n.)

"Trapeze" is a noun that refers to a swing with a cross-bar, which is used for feats of strength and agility. It originated in 1861 from the French word trapèze,, which came from Late Latin trapezium (see trapezium). The name "trapeze" was probably given because the crossbar, ropes, and ceiling formed a trapezium shape.
