Etymology Origin:
The word extrude originates from Latin extrudere, combining ex- ("out") and trudere ("to push"). It entered English in the 16th century, initially describing physical expulsion. Over time, it specialized in industrial contexts, particularly in manufacturing processes where materials are forced through molds. The morphemes ex- and trude remain transparent, reflecting the action of "pushing out."
