## AI Etymology
Supersede comes from Latin supersedere ('to sit above; to be superior to, refrain from'), from super- ('above') + sedere ('to sit'); via Old French superseder and Middle English superseden ('to defer, replace'). In current use it is a verb meaning "to replace something with something newer or more effective". 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.
