Origin of lasso

1760–70; < Spanish lazo < Latin laqueus noose, bond; see lace

Explanation

A lasso is the loop of rope that cowboys use to catch cattle. To be a successful cowboy or cowgirl, you have to learn to throw a lasso while riding a galloping horse. The circle of rope is called a lasso. and to lasso is to use it to catch a runaway animal. A child might lasso her stuffed animals while riding a rocking horse, and during a rodeo, cowboys who specialize in "trick roping" use their lassos to do fancy spinning tricks. Lasso was coined in the U.S. around 1807, from the Spanish lazo, and its Latin root laqueum, both meaning "noose" or "snare."
