Root Breakdown
Root-derivedex- (out) + trud (push) = "push out." In modern use it's an industrial term: machines extrude plastic, metal, or pasta by forcing it under pressure through a shaped opening (a die), so it comes out in a fixed cross-section — tubes, wires, frames. The shove is aimed straight out through a hole.

Mostly a technical/industrial word (manufacturing, materials science): extrude metal, plastic, rubber, or food. Its noun extrusion names both the process and the product (an aluminum extrusion). Rare in everyday speech — for ordinary "sticking out," use protrude or stick out instead.
