The word "refine" combines the Latin prefix "re-" (meaning "again") with the Latin root "fine" (derived from "finis," meaning "end" or "pure"). Originally, "fine" referred to something of high quality or purity. Over time, "refine" evolved to signify the process of improving or purifying something through repeated effort, such as refining metals or ideas. The logic reflects iterative enhancement—doing something "again" to achieve a "finer" state.
