## AI Etymology
Refine comes from re- ('again, expressing intensity') + fine, modeled on French raffiner. Fine is from Old French fin ('perfect, pure'), from Latin finis ('end, limit, boundary'). The prefix supplies the first semantic turn, while the base carries the lexical core of the word. As a verb, it means "to remove impurities from, or to improve by making small changes", so the modern sense keeps the older action or relation visible. Relevant historical forms include Latin re-, Old French fin, and Latin finis. Derivative forms include refined, refinement, refiner, refinery, refining; related words include fine, define, finesse.
