This doesn’t really happen to me all that much, to be honest. I like knowing things, a lot. I distinctly remember answering a prompt about being the Patron Saint of something, and here is my answer. If there’s a word I want to use, I tend to run to the dictionary or Google, look it up before I ever use it. Poncy though it may sound, I like knowing things too much to ever misuse a word.
Although there was the one time that I used “inherent” in conversation, when I wasn’t quite sure what it meant. I looked it up later, and it turned out I had used it correctly, so well done me. If I do have any wordy misadventures, I shall be sure to let you know.
