Etymology: "Refiners" is the plural of "refiner," formed from the verb "refine" plus the agent suffix "-er," so it means people or firms that refine. "Refine" comes from Old French "raffiner," meaning to purify or make finer, built from "re-" and "fin," meaning fine or pure, which is the same root that gives English "fine" in the sense of pure or free from impurities. The noun "refiner" describes a person whose work is refining, and the same logic applies whether the substance is metal, sugar, petroleum or grain. In that sense the word is a transparent agent noun: anyone who refines is a refiner, so the plural names the whole group of such workers at once.

Synonyms: purifiers, processors, improvers
