## AI Etymology
inversion comes from Latin inversio, from invertere 'to turn upside down' (from in- 'in, upon' plus vertere 'to turn'). Morphologically, the prefixed shape matters: the initial element belongs to the recorded formation and helps explain the modern form's surface analysis. In present English, the noun sense is "a reversal of position, order, or relationship", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as invert, inverse, and inversive, and in derivatives such as inversional. Its semantic neighborhood includes reversal, transposition, reverse, and turnabout, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Latin inversio and Latin vertere.
