Etymology
The verb "extrude" is a direct borrowing from the Latin extrudere, which is a compound of the prefix ex- ("out") and the verb trudere ("to thrust, push"). This literal sense of "thrusting out" was carried directly into English in the mid-16th century. Initially used in general contexts for forcing something out, its application narrowed with the industrial revolution to describe specific manufacturing processes, such as shaping plastic or metal by forcing them through a die. Thus, the word's journey maintains a clear logical thread from the physical act of pushing out in Latin to its precise technical meaning in Modern English.
Analysis
- ex: latin origin, a prefix meaning "out, out of, from". - trude: from latin trudere, meaning "to thrust, push".
