Did you know?

In Latin rodere means "to gnaw" and radere means "to scrape." The latter word is at the base of both "abrade" and "corrade." "Corrade," which carved its niche in the English language during the mid-17th century, is used when something, such as moving water, "rubs" or "scrapes" something else away. In contrast, the word corrode, derived from "rodere," is fitting when something "eats away" at something else especially by chemical action. "Erode" shares that meaning but can also be used to describe abrasive action, much like "corrade." As an aside, the gnawing of small animals, such as mice and squirrels, influenced the formation of the noun "rodent" through "rodere."
