## AI Etymology
Multiplexer comes from Latin multi- ('many') plus plex- ('to fold; to twist'), giving Latin multiplex ('manifold; many-fold'); the modern technical term multiplexer denotes an electronic device that selects or combines several signals. In current use it is a noun meaning "an electronic device that selects one of several input signals to send to a single output". That sense is explained by the older material without requiring a speculative semantic step: the inherited or borrowed base supplies the field of meaning, while the English formation fixes its modern role. The surface form is compositional: its joined elements remain visible in the modern word. The word's history is thus visible in its construction: the components remain interpretable even after the whole expression has settled into a conventional English meaning.
