| Back | verb To wear or crumble away through abrasion. [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."] "The nearly pyramidal shapes in the Cydonia region of Mars -- which recent imagery suggest are likely no more than ancient mountains corraded by eons of sandstorms -- were advanced by the late astronomer Carl Sagan and others as sites to be examined by future missions to Mars as potential artifacts of intelligence." |
