You might gnaw on a corn cob, or gnaw a piece of watermelon, or gnaw away at any other food that takes a lot time to chew. When I have a soda with a plastic straw, I like to gnaw on the straw! But I only do it at home, with just my family! Gnawing tends to be a messy, sloppy, impolite kind of chewing.
And when pains or bad thoughts or feelings gnaw at you, they bother you again and again. You might feel a gnawing hunger if you have to wait too long to eat, or a gnawing ache if you stubbed your toe really hard an hour ago. Or, you might feel a gnawing worry, or a gnawing sense of fear, the night before you start a new school year.
You might be wondering, "What's up with the silent G in this word?" Well, it comes from Old English, and back then, people actually pronounced the G. We don't anymore. Why? I don't know! That question is really gnawing at me!
