Etymology: "Nonstaining" is a plain compound: the prefix "non-", meaning "not", attached to "staining," the present participle of the verb "stain." Stain itself came into English from Old French "desteindre," meaning "to remove colour," and it was later reshaped by the Middle English "steinen," which meant to colour or dye. So the word's ancestry runs through the idea of colouring cloth, not of marking it. The prefix has a longer history. "Non-" descends from the Old English "nān," meaning "not one," which was worn down over centuries into the Middle English "non" and eventually became the separate prefix used to negate words such as "nonstop" or "nonfiction." Because the prefix was still productive in English, speakers could attach it freely to almost any participle, and "nonstaining" follows that pattern.
