Etymology: "Demineralised" is built from the prefix "de-", meaning "removing or reversing," plus "mineralise," which in turn comes from "mineral." The root traces back to medieval Latin "minerale," used for things dug out of the earth, and the English verb "mineralise" dates from the 1600s, when it meant to turn a substance into a mineral or to impregnate something with minerals. The "de-" prefix came into English from Latin, where it meant "down" or "away," and in chemistry it came to mean removing a component. Demineralisation as a technical process developed much later, in the nineteenth and twentieth centuries, as industries such as boiler operation and water treatment needed ways to strip dissolved salts and calcium from water. The adjective therefore describes an idea that is essentially modern, even though every part of it is centuries old.
