Etymology

Origin of erode

First recorded in 1605–15; from French ė́roder or directly from Latin ērōdere, equivalent to ē- “out of, from” + rōdere “to gnaw”; see e- ¹

Explanation

While erode is most commonly used when describing land loss, you can also use it in less literal ways. Numerous hospital bills can cause your savings to erode. Each time you catch your friend in a lie, your trust in her erodes a little more. Consumer confidence is eroding away as the media reports more and more bad economic news. What’s key here is both the sense of loss, as well as the idea that it is a gradual process.
