Last week at the grocery store, I heard a young man tell his friend he felt “nauseous” about an upcoming interview. Instead of correcting him, I watched as he shared his worries. It reminded me how tricky English can be, even for the educated.
After decades of teaching high school English, I’ve seen even the best stumble over words. English is messy. It borrows from other languages, breaks rules, and changes constantly.
During my career, I collected common misused words. What struck me wasn’t just the mistakes but the confidence with which people made them. Many believe they’re using words correctly.
Let’s dig into nine words that trip people up.
Literally: This word means something happened exactly as stated. Yesterday, someone claimed to be “literally dying” of embarrassment. Unless they needed medical attention, they meant “figuratively.” This mix-up is so common that some dictionaries accept the lighter usage, but knowing the true meaning can make you stand out.
Ironic: Alanis Morissette’s song “Ironic” is filled with examples that aren’t really ironic. A wedding day rain isn’t ironic; it’s just bad luck. True irony shows a twist in expectation, like a fire station catching fire. I once had a student argue it was ironic that their dog ate their homework. The irony? They hadn’t completed it in the first place!
Disinterested vs. Uninterested: Disinterested means impartial, like a fair judge. Uninterested means you simply don’t care. In jury selection, lawyers want disinterested jurors, not uninterested ones. Remember: a neutral referee? Good. An uninterested one? Not so much.
Nauseous vs. Nauseated: The young man wasn’t wrong; he just mixed them up. If you’re feeling sick, you are nauseated. If you cause that feeling in others, you’re nauseous. Though language evolves, knowing the difference can show attention to detail.
Comprise vs. Compose: This one confuses many. The whole comprises its parts; the parts compose the whole. You’d say “the United States comprises fifty states,” not “comprised of.” Spotting this error often means you’ve mastered the basics!
Affect vs. Effect: This mix-up happens even among graduates. Affect is a verb meaning to influence. Effect is a noun that refers to a result. For example, “The weather can affect your mood” is correct, while “The effect of sunshine is happiness” demonstrates how to use the two properly.
Farther vs. Further: Think of “farther” for physical distance and “further” for abstract situations. You drive farther on a road, but look further into a problem. Associating “far” with physical distance can clarify your usage.
Fewer vs. Less: I can’t stand seeing “10 items or less” at the store! Use “fewer” for things you can count, like cookies, and “less” for things you can’t measure directly, like sugar.
Who vs. Whom: While fewer people use “whom” these days, it still has a place. “Who” is for subjects, and “whom” is for objects. If you can swap it for “he” or “she,” use “who.” If you can replace it with “him” or “her,” stick with “whom.”
Language keeps shifting, and some distinctions may fade away. That’s okay. Right now, using these words correctly shows you care about clear communication.
In my gratitude journal tonight, I’ll remember that young man at the grocery store, not for his word choice, but for his vulnerability. We’re all navigating this language together, and that’s what makes us human.
