The link between the Latin word "corrodere," meaning "to gnaw to pieces," and our word "corrode" is pretty clear. Can you guess which answer gives another meaning of "corrode"?To see the connection between the two meanings of "corrode," think about how something getting eaten away by degrees would gradually weaken and eventually be destroyed. Even though these meanings are connected, we use them in different situations. We use the "eat away" sense of "corrode" to talk about physical things, like metal, that can become corroded over time. When we use the "weaken" sense of "corrode," it is most often to talk about things we can't touch, like feelings or traditions.
