Etymology
the word extruder is built upon the verb extrude, which entered english in the 16th century from latin extrudere, meaning "to thrust out". this latin verb itself is a compound of the prefix ex- ("out") and trudere ("to thrust, push"). the core root trud- can be traced back to the proto-indo-european root treud-, meaning "to press, push, squeeze", which also gave rise to words like threat and thrust. the english agent suffix -er was later appended to form "extruder", logically naming a person or, more commonly, a machine that performs the action of forcing material out through a die or opening.
Analysis

ex: latin origin, a prefix meaning "out of, from, thoroughly".
