Etymology: "Demineralising" is the present participle of "demineralise," which is formed from the prefix "de-" plus "mineralise." The prefix means "remove or reverse," so the verb literally means to take minerals out of something. "Mineralise" itself comes from "mineral," which traces back through Medieval Latin "minerale" to the Latin "minera," a mine or ore. The verb's sense is quite literal: it describes stripping dissolved mineral salts from water or another material. The mineral sense is the older one; the prefix simply reverses it. The same pattern appears in words like "decaffeinate" and "dehydrate," where "de-" marks removal from something. Because the word is a plain prefix-plus-verb formation, its history is simple. Its meaning follows directly from its parts, which is why the process it names, removing mineral content from water to prevent scale, is easy to read straight from the word itself.
