Etymology: "Arrosion" comes from Latin "arrodere," meaning "to gnaw," built from "ad-" ("to") and "rodere" ("to gnaw"). The past participle "arrosum" gave the root that English took up as a noun for the process of being slowly eaten or worn away. The image is literal: something nibbled at, bit by bit, until it gives way. The word reached English by way of French, which has its own form, "arrosion," with the same sense. That makes it a word that passed through French rather than coming straight from Latin, though the two languages share the same stem. The Latin verb "rodere" is also the source of English "rodent," which is a useful way to remember the sense of gnawing that lies underneath.
