Etymology

Origin of truss

First recorded in 1175–1225; Middle English verb trussen, from Old French tr(o)usser, variant of torser, probably from unattested Vulgar Latin torsāre, derivative of unattested torsus, for Latin tortus, past participle of torquere “to twist, wind, wrap”; Middle English noun trosse, trus, trusse “bundle,” from Old French trousse, torse, derivative of torser

Explanation

A truss is a framework that supports something, like a roof or a bridge. A steel beam that holds up a bridge is called a truss. Another kind of truss is a similar structure that's designed to support a roof. A truss refers to part of the design of a bridge, overpass, or building; or a medical device that keeps a hernia from bulging. Either way, a truss offers support. You can also use truss as a verb meaning "tie up." Many cooks are familiar with a recipe's instruction to truss a goose, for example, tying its wings and legs together before cooking it. A truss was originally "a collection of things bound together," with the Vulgar Latin root torciare, "to twist."
