As an author and a public speaker, I’m careful to use accurate words in professional situations. In casual situations, I’m much more prone to language misuse. Here are two recent casual examples:
On the subject of humor: I mentioned, how for me, I’m most successful getting people to laugh when I use self-depreciating humor. (I should have said “self-deprecating humor.”)
On the subject of Donald Trump: I mentioned how each day he gets excrementally worse. (I should have said “incrementally worse.” Hmm. . . . Now that I think about it. Perhaps my original words were correct too.)
