If you’ve ever told someone they have "another thing" coming, I hate to be the one to break it to you, but you’re technically part of a massive linguistic misunderstanding. It sounds right. It feels right. But it’s fundamentally a mistake. Honestly, the phrase you have another think coming is the original, logically sound version of the idiom, and the fact that most of the world now says "thing" instead is a fascinating study in how English evolves through collective error.
Language is messy. It’s not a stagnant set of rules carved into a stone tablet; it’s a living, breathing, often chaotic medium that changes because we’re all a little bit lazy with our vowels and consonants. But for the purists, the history of this specific phrase is a hill worth dying on.
Where "Another Think" Actually Came From
The logic is pretty straightforward once you see it. The full expression, popularized in the 19th century, used to be: "If you think that, you have another think coming." It’s a bit of a play on words. It implies that your first "think" (your initial thought or assumption) was so catastrophically wrong that you need to go back to the drawing board and try a second one.
According to the Oxford English Dictionary, the noun "think" (as in "to have a think") emerged in the mid-1800s. By the late 1800s, British and American publications were regularly using the full "another think" phrasing. For instance, a 1897 edition of The Sunday Oregonian featured the phrase in a context that clearly highlighted the "think/think" symmetry. It’s a linguistic mirror.
If you say "another thing," the symmetry disappears. What is the first thing? Nobody knows. The sentence loses its snarky, intellectual punch.
The Judas Priest Effect and the Great Shift
So, how did we lose our way? You can’t talk about this phrase without mentioning the 1982 heavy metal anthem by Judas Priest. Their hit "You've Got Another Thing Comin'" arguably did more to cement the "thing" version in the global consciousness than any other single event.
Rob Halford belts it out with such conviction that it sounds absolutely correct. When a legendary rock frontman screams a lyric into the ears of millions, that lyric becomes the new reality. Pop culture has a way of steamrolling over etymology.
But it’s not just metalheads. Humans are prone to "mondegreens" or misheard phrases. "Another think coming" requires a hard "k" sound followed immediately by a "c" sound. It’s clunky. It’s a bit of a tongue twister if you’re speaking quickly. Over time, "think coming" softened into "thing coming." It’s easier to say. We’re efficient—or lazy—creatures.
Why the "Thing" Version Still Kind of Works
Even though it’s technically a corruption, language experts like those at Merriam-Webster acknowledge that "another thing coming" has become so ubiquitous that it’s now considered an accepted variant. That’s just how English works. If enough people say something "wrong" for long enough, it becomes "right."
Think about the word "nice." Hundreds of years ago, it meant "ignorant" or "foolish." Now it’s a compliment. The shift from "think" to "thing" is just another chapter in that book.
However, using the original you have another think coming marks you as someone with a deep, perhaps slightly pedantic, understanding of English. It’s a shibboleth. It tells the listener, "I know the history of what I’m saying."
The Logic Gap
Let’s look at the two phrases side-by-side.
- Version A: "If you think I’m going to pay for that, you have another think coming."
- Version B: "If you think I’m going to pay for that, you have another thing coming."
In Version A, the "think" is the act of rethinking. In Version B, what is the "thing"? Is it a punishment? A surprise? A bill? It’s vague. While Version B has a certain ominous energy to it—suggesting a mysterious "thing" is headed your way—it lacks the sharp wit of the original.
Real-World Usage and How to Not Sound Like a Jerk
If you decide to start using the original phrase, you’re going to run into people who try to "correct" you. It’s inevitable. You’ll say, "You have another think coming," and they’ll smirk and say, "Actually, it’s thing."
Don't be the person who delivers a 20-minute lecture on 19th-century linguistics at a cocktail party unless you’re looking to be left alone by the snack bowl. Just know that you’re right.
But there are places where the distinction matters. If you’re a novelist writing a period piece set in the 1920s, having a character say "another thing coming" would be a glaring anachronism. In formal writing, or if you’re trying to impress a particularly old-school editor, "another think" is the way to go.
Does it actually matter?
Honestly? In the grand scheme of things, maybe not. Language is for communication. If the person you’re talking to understands that you’re telling them they’re wrong, the phrase has done its job. But there is a certain beauty in the precision of the original.
We live in an era where "literally" now officially means "figuratively" in some dictionaries. We’re losing the fine edges of our vocabulary. Holding onto you have another think coming is a small way of preserving the logical structure of our idioms.
How to Win the Argument (if you must)
If you find yourself in a heated debate about this at a bar or in a Reddit thread, here is your ammunition.
- Point out the symmetry. Explain that the phrase is a response to the verb "to think."
- Cite the OED. The Oxford English Dictionary is the gold standard, and it backs the "think" camp.
- Explain the "softening" of consonants. Mention how "k" sounds often morph into "g" sounds in casual speech (assimilation).
- Mention the 19th-century origins. It wasn't just a random mistake; it was a clever turn of phrase.
Actionable Steps for the Word-Conscious
If you want to refine your usage and help keep the original phrase alive, here’s how to handle it moving forward.
Audit your own speech. Most of us use idioms on autopilot. Next time you’re about to use the phrase, pause. Try out the "think" version. It might feel weird at first—like wearing a new pair of shoes that are slightly too stiff—but you’ll get used to it.
Context is everything. In a casual text to a friend about a movie, "another thing" is fine. No one cares. In a legal brief, a published essay, or a historical screenplay, stick to the original.
Watch for other "Eggcorns." An eggcorn is a word or phrase that results from a mishearing, like "old-timers' disease" for Alzheimer’s or "for all intensive purposes" instead of "all intents and purposes." Once you realize you have another think coming is the original, you start seeing these linguistic ghosts everywhere.
Don't be a snob. Knowledge is a tool, not a weapon. Use the correct version because it’s accurate, not because it makes you feel superior to the person across the table who just quoted Judas Priest.
The evolution of this phrase is a perfect example of how human error, pop culture, and the simple desire for "easier" speech can rewrite the rules of a language. Whether you stick with the original or succumb to the popular "thing," at least now you know the truth behind the "think."
