I was surprised one day to learn that “skedaddle” was a real word. I had assumed it was some sort of slang word that parents used to get their children moving. With that realization, I began listening for other words that are kind of funny, but are actually listed in the dictionary. Here is my list so far. Feel free to add to it in the comments:
