Simplified etymology

Extrude, recorded from the mid-16th century, comes from Latin extrudere, formed from ex- “out” and trudere “to thrust.”

Borrowed from Latin extrudere, 'to thrust or drive out,' formed from ex-, 'out,' + trudere, 'to thrust.' Industrial manufacturing narrowed one major sense to forcing softened material through a shaped opening.
