The word "rollover" combines "roll," derived from Old French roller (to revolve) and Latin rotulare (to make circular), with "over," from Old English ofer (above/across). The term originally described physical motion (e.g., a vehicle rolling over) but expanded metaphorically to finance (renewing investments) and computing (interactive hover effects). The morphemes retain their core meanings—"roll" implies motion, while "over" suggests transition or completion.
