If you've ever paused mid-sentence wondering whether it's bated breath or baited breath, here's the direct answer: bated breath is correct, and baited breath is a common misspelling of it. "Bated" is a shortened form of "abated," meaning reduced or held back, so "bated breath" describes breathing that has almost stopped under strong emotion, such as suspense, fear, or anticipation. "Baited breath" borrows the spelling used for fishing hooks and traps, and it has no place in the phrase's history. The correct form goes back to Shakespeare, who used it in The Merchant of Venice around 1596.
Bated Breath or Baited Breath: The Quick Answer
Use bated breath. It appears in every major dictionary and style guide as the standard spelling, and it is the form professional editors expect to see. Baited breath is an eggcorn, a misspelling that swaps in a more familiar word because the correct one has fallen out of everyday use. Spellcheck will not always catch it, because "baited" is a real word; it is just the wrong one here.
The confusion is understandable. "Bated" and "baited" are homophones, pronounced identically, and "bate" as a standalone verb almost never appears anywhere else in modern English. When a word survives in only one fixed phrase, writers reach for whichever spelling looks familiar, and "baited" wins that contest for most people.
What "Bated" Actually Means
"Bated" comes from "abated," which means to lessen, reduce, or die down in force. Drop the unstressed first syllable of "abated" and you get "bated," a process linguists call aphesis. The same shortening pattern shows up elsewhere in English, though few of those words survive as long as this one has.
So "bated breath" is breath that has been reduced in intensity, breathing so shallow and controlled it is barely there. That is exactly the physical sensation the phrase describes: the held, quieted breathing of someone waiting for a verdict, a result, or news that could go either way. The meaning lines up with the etymology precisely, which is one reason references treat "bated" as settled rather than disputed.
Why So Many People Write "Baited Breath"
"Bait" is a common, everyday word: you bait a hook, bait a trap, bait an argument. "Bate" is not. Outside this one idiom, the verb "to bate" has essentially disappeared from spoken and written English, so when people hear the phrase out loud, their ear supplies the word they actually know. The result is an image of breath being used to lure something, which makes no literal sense, but idioms are not judged for literal sense once they are fixed in the language.
This kind of substitution is not unique to this phrase. The same pattern, an unfamiliar or archaic word getting swapped for a familiar-sounding one, is exactly what produced the confusion behind kick the bucket, where an old, less-common sense of "bucket" was replaced in the popular imagination by the everyday pail. Once a word drops out of general use, the version of the phrase that survives in people's memory is often the one that sounds right, not the one that is right.
Even professional editors miss it. J.K. Rowling's Harry Potter and the Prisoner of Azkaban famously prints "the whole common room listened with baited breath," an error that made it past several rounds of editing and into millions of copies. If a published novel can slip, a quick email or a first draft can too.
Where the Phrase Comes From
The earliest citation every major reference agrees on is Shakespeare's The Merchant of Venice, written around 1596 to 1599 and first published in 1600. Shylock says to Antonio: "Shall I bend low and, in a bondman's key, / With bated breath and whisp'ring humbleness, / Say this…" In that line, "bated" describes Shylock subduing his own breath and voice as a gesture of forced deference, which is a slightly different shade of meaning than the anticipatory suspense the phrase carries today, but the same reduced, restrained sense of "bated" runs through both.
According to Merriam-Webster, writing in its Words at Play feature on so-called "fossil words," the verb "bate" goes back to the 14th century as a shortened form of "abate," but it fell out of everyday use by around the end of the 19th century (accessed 2026-09-18). "Bated breath" is one of the last places the word survives, fossilized inside a single fixed phrase, which is precisely why the spelling trips people up. Etymonline traces the same root, describing "bate" as an aphetic form of "abate" derived ultimately from the Old French "abattre," meaning to beat down or reduce (accessed 2026-09-18).
Unlike some idioms on this site, this one is not a case of a folk story being retrofitted onto an old phrase. The citation trail is short, consistent, and points to one writer and one play. There is no competing origin theory worth weighing against it, which puts it in a different category from an idiom like raining cats and dogs, where no reference has ever settled the question at all.
That stability is unusual for an idiom this old. Most fixed phrases from Shakespeare's era have drifted in wording, in meaning, or both, but "with bated breath" has kept the same three words and close to the same sense for more than four centuries, changing only in the kind of anticipation it now describes: less forced humility, more excited or anxious waiting.
How to Use "Bated Breath" Correctly
"Bated breath" almost always appears inside the fixed phrase "with bated breath." It works in both American and British English, and it sits comfortably in formal, neutral, and even literary writing; it is not a casual-only expression the way some idioms are.
| Register | Region | Status | |
|---|---|---|---|
| with bated breath | neutral to literary; fine in formal and edited writing | both US and UK | current, correct |
| with baited breath | none; treated as an error everywhere | not applicable | misspelling |
A few natural examples:
- "Fans waited with bated breath for the final score."
- "She opened the envelope with bated breath."
- "The whole office listened with bated breath as the numbers were announced."
You'll see the phrase most often in fiction, sports writing, and news coverage of anything with an uncertain outcome: an election, a verdict, a playoff game, a job offer. It rarely stands alone; almost always it is attached to a verb of waiting or watching, such as "wait with bated breath" or "watch with bated breath." That consistency is part of why editors notice the misspelling quickly. Because the phrase shows up in a narrow, predictable set of contexts, "baited breath" stands out fast to anyone who reads it often, the way a familiar face looks wrong with the wrong haircut.
Notice that "bated breath" almost never stands alone outside "with." That fixed pattern is itself a clue: when a word only ever appears in one slot of one phrase, it is usually a sign the word has fossilized, exactly as Merriam-Webster describes.
Bated Breath vs Other Idioms People Get Wrong
"Bated breath or baited breath" belongs to a large family of English expressions where the wrong version has become genuinely common, sometimes more common in casual writing than the correct one. Some of these mix-ups involve a misheard word, like this one. Others involve a popular origin story that turns out not to hold up: the false explanation behind bite the bullet, for instance, is not a spelling problem but an entire invented history that spread anyway because it sounded plausible.
Other idioms sit somewhere in between, where the wording is stable but the backstory is not. Let the cat out of the bag is often explained with a specific market-fraud story that no reference can actually source, the same way "baited breath" sounds like it should make sense once you picture a fishing line. In both cases, a memorable image fills in for a citation, and the image is usually wrong.
The lesson for "bated breath" is the same lesson that applies across all of these: when a phrase feels like it should mean something literal, check whether it actually does before repeating the explanation. Here, it takes one look at Shakespeare's own line to see that the "bait" story was never in the text at all.
Frequently Asked Questions
Is it "bated breath" or "baited breath"?
"Bated breath" is correct. "Baited breath" is a common misspelling caused by the words being pronounced identically. Every major dictionary and style guide records "bated breath" as the standard form.
What does "bated breath" mean?
It means holding your breath, or breathing very shallowly, because of strong emotion such as suspense, fear, or anticipation. "Bated" comes from "abated," meaning reduced or lessened, so "bated breath" is literally breath that has been reduced almost to nothing.
Why do people write "baited breath" instead?
Because "bate" as a standalone verb has almost disappeared from modern English, while "bait" is a common, familiar word. When people hear the phrase spoken aloud, their ear substitutes the word they actually know, which produces an image of breath being used to lure something, even though that reading has no basis in the phrase's history.

The earliest citation every major reference agrees on is Shakespeare's The Merchant of Venice, written around 1596 to 1599, in a line spoken by Shylock: "With bated breath and whisp'ring humbleness."
Is "baited breath" ever acceptable to use?
No. It is treated as an error in edited writing, formal writing, and by style guides generally. It may pass unnoticed in casual speech because the two forms sound identical, but in writing it is simply the wrong spelling of the idiom.
