Corrode comes from Latin corrodere ("to gnaw to pieces"), a combination of the suffix "cor-" (used here as an intensifier with the meaning of "completely") and the verb "rodere" ("to gnaw"). At one time, "corrode" was used to literally indicate the action of gnawing away, as in "woodworms corroded the wood." But it is the more figurative senses from the action of gnawing or eating away that have persisted, as in "salt water corroded the iron" or "graphic content on television and the Internet is corroding the moral fabric of society."
: to slowly break apart and destroy (metal, an object, etc.) through a chemical process
