Etymology: The plural here is simple, but the word it comes from has a more interesting trail. "Refinery" is formed in English from "refine" plus the suffix "-ry", which turns a verb into a word for a place or activity, as in "bakery" or "foundry". The verb "refine" itself came into English from Old French "raffiner", meaning to make finer or purer, built on "fin", "fine". So a refinery is, literally, a place where things are made fine. The "fine" in that chain is the same word that gives English "fine" in the sense of pure or thin, which is why refining has always meant removing impurities. Early refineries were places for purifying sugar, salt, metals and, later, oil. The "-ry" ending is a native English pattern rather than a borrowed one, so the whole word is a hybrid of French and English parts.
