Etymology

Origin of extrude

1560–70; < Latin extrūdere to thrust out, drive out, equivalent to ex- ex- ¹ + trūdere to thrust, push

Explanation

If you force material through an opening to give it form or shape, you are extruding the material. You can use a pasta maker to extrude the pasta dough in various shapes — from spaghetti to linguine to macaroni. Extrude is from the Latin word extrudere, which itself can be broken into the roots ex-, meaning "out," and trudere, meaning "to thrust." In the noun form, the process is called extrusion. You can extrude all kinds of materials and products by forcing them through an opening, including cheese puffs, pasta, candy, plastic toys like the hula hoop, assorted pipes and hoses, and glass tubing.
