3. It’s incorrect to answer the question “How are you?” with the statement “I’m good.” Wrong! Am is a linking verb and linking verbs should be modified by adjectives such as good. Because well can also act as an adjective, it’s also fine to answer “I’m well,” but some grammarians believe “I’m well” should be used to talk about your health and not your general disposition.
I learned that I was wrong on a few of these.
