Did You Know?
Once upon a time, English had two different but similarly derived words meaning "to wear down": "abrade" and "abrase." However, in this fairy tale, only one of the two had a happy ending; while "abrade" remains a familiar word to modern English speakers, "abrase" has become quite rare. And yet, "abrase" lives on in its descendant "abrasive," which was formed by combining the verb with the "-ive" suffix. Both of the verbs, and by extension "abrasive," can be traced back to the Latin verb "abradere," meaning "to scrape off." "Abradere" in turn was a combination of "ab-" and "radere," meaning "to scrape."
