Per Say or Per Se? Which Is Correct?

Ever typed “per say” in an email and then paused, wondering if you just made a mistake? You’re definitely not alone. This is one of the most commonly confused phrases in English, and honestly, the confusion makes complete sense once you understand why it happens.

Here’s the short answer before we dive deep: “per se” is correct, and “per say” is always wrong. No dictionary, style guide, or grammar authority recognizes “per say” as a real word or phrase. It’s simply a phonetic slip-up that happens because of how the phrase sounds when spoken aloud.

But knowing the right spelling is only half the battle. In this guide, we’ll break down exactly what “per se” means, why so many people misspell it, how to use it correctly in real sentences, and where this odd little Latin phrase even came from. By the end, you’ll never second-guess yourself again.

What “Per Se” Really Means

“Per se” is a Latin phrase that literally translates to “by itself” or “through itself.” In everyday English, it’s used as an adverb to mean “in itself,” “intrinsically,” or “inherently.”

When you use “per se,” you’re telling your reader or listener that something should be judged on its own terms, separate from outside factors, opinions, or comparisons. It’s a handy way to add nuance to a statement without writing a whole extra sentence.

For example:

• The idea isn’t bad per se, but it needs more research.
• I don’t dislike her per se; I just don’t trust her judgment.
• The product isn’t expensive per se, but it’s overpriced for what it offers.

Notice the pattern? “Per se” almost always shows up in sentences that soften or qualify a statement. It signals: “on its own merits, this is true, but there’s more nuance here.”

Why “Per Say” Is Incorrect

Let’s clear this up once and for all: “per say” has no meaning in the English language. It isn’t in Merriam-Webster, Oxford, or any credible dictionary. It’s what linguists call an eggcorn, a phrase that gets misspelled because it sounds like something else that seems logical.

Think about it. “Per se” is pronounced almost exactly like “per say,” so when people hear it in conversation before ever seeing it written down, their brain naturally fills in the more familiar English word “say” instead of the unfamiliar Latin word “se.” It’s an easy mistake, especially since English doesn’t have many words that end in a lone “se” pronounced like “say.”

Here’s a simple table to make the difference crystal clear:

Once you understand that “se” comes directly from Latin and isn’t meant to follow English spelling logic, the confusion starts to make a lot more sense.

Understanding Correct Usage

Using “per se” correctly comes down to placement and context. It typically appears after the noun, verb, or idea it’s modifying, not before.

Correct:

• The plan isn’t flawed per se.

Incorrect:

• Per se, the plan isn’t flawed. (technically not wrong, but far less natural)

While it’s grammatically possible to place “per se” at the start of a sentence, native speakers rarely do this. It reads more naturally when tucked into the middle or end of a sentence, right after the concept it’s clarifying.

Also, don’t confuse “per se” with similar-sounding or similar-meaning phrases like “as such” or “so to speak.” While there’s some overlap, “per se” specifically emphasizes that something is being evaluated on its own, independent of outside context.

Grammar Rules and Style Tips

Here are a few quick rules to keep in your back pocket:

• No hyphen needed. Write it as two separate words: per se.
• No comma required, though some writers add one for stylistic pause, both are acceptable.
• Italics are optional. Since “per se” has become common in everyday English, most style guides no longer require italicizing it, though academic or legal writing sometimes still does.
• Don’t overuse it. Like any phrase, repeating “per se” multiple times in the same paragraph makes writing sound clunky and repetitive.
• It’s an adverb, not a noun or adjective. It modifies actions or ideas, not people or objects directly.

Common Contexts Where “Per Se” Appears

You’ll spot “per se” popping up across several different fields, and its meaning shifts slightly depending on where it’s used:

• Legal writing, This is where “per se” is used most precisely. Terms like “negligence per se” describe an act that is automatically considered negligent because it violates a law or regulation, without needing extra proof of carelessness.
• Academic and formal writing, Often used to isolate one variable or idea from a broader argument.
• Everyday conversation, Frequently used casually to soften criticism or add a qualifier (“It’s not bad per se…”).
• Business and professional communication, Common in emails and reports when clarifying that a statement applies narrowly.

Historical and Linguistic Context

“Per se” has been part of the English language for centuries, borrowed directly from Latin, where “per” means “through” or “by,” and “se” is a reflexive pronoun meaning “itself.” Unlike many Latin-derived words that eventually got anglicized in spelling, “per se” kept its original Latin form intact.

This is actually pretty common with Latin legal and academic terminology, think of phrases like “de facto,” “status quo,” or “vice versa.” These expressions retained their Latin spelling because they became standard in formal writing, particularly in law, philosophy, and academia, long before they trickled into casual speech. That’s part of why “per se” still looks and feels a little foreign compared to the rest of everyday English vocabulary.

Sound Traps and Mispronunciations

The entire “per say” mix-up boils down to one simple sound trap: “per se” is pronounced “per-SAY.”

Since most people learn the phrase by ear, hearing it in movies, conversations, or on the news, long before they ever read it, their brain automatically links the sound to the more familiar spelling pattern of English words ending in “-ay.” This is exactly how eggcorns form, and “per say” is one of the most widespread examples in modern writing.

A good trick to remember the correct spelling: think of other Latin phrases that keep unusual, non-English spellings, like “de facto” or “carpe diem.” “Per se” belongs in that same family, so it doesn’t follow standard English phonetic rules.

How to Use “Per Se” Effectively

Want your writing to sound polished and intentional? Here’s how to use “per se” the way skilled writers do:

1. Use it to add nuance, not just as filler. Only include it when you genuinely want to isolate one idea from the bigger picture.
2. Pair it with a qualifying clause. “Per se” works best in sentences that continue with “but” or “though” to explain the fuller context.
3. Keep sentences concise. Don’t overload a sentence with extra clauses just to fit “per se” in, let it flow naturally.
4. Reserve it for precision. In legal or academic writing, use it only when you mean something is true independently, without outside influence.

Common Misuses and Examples

Let’s look at some real side-by-side comparisons to lock in the difference:

Notice how every “incorrect” example still reads smoothly when you swap “say” for “se”, that’s exactly why so many people don’t catch the mistake when proofreading. Your ear tells you it’s right, but your eyes need to know it’s spelled differently.

Expert Insights

Language experts and editors consistently point to “per se” as a classic example of how pronunciation shapes spelling errors in English. Because so much everyday vocabulary is absorbed through listening rather than reading, phrases borrowed from other languages, especially ones with unfamiliar spelling patterns, are particularly vulnerable to being “corrected” by our brains into something more familiar-looking, even when that correction is wrong.

Professional editors and grammar tools consistently flag “per say” as an error, which is a strong signal that even seasoned writers occasionally slip up here. If you want a quick way to double-check, most modern grammar checkers will automatically flag “per say” as a misspelling.

Pop Culture References

You’ve likely heard “per se” used casually in movies, TV shows, and even in the name of restaurants and brands (there’s a well-known fine-dining restaurant literally named “Per Se” in New York City, playing on the phrase’s meaning of something standing on its own). Its frequent use in dialogue, especially in legal dramas and workplace sitcoms, is a big reason the phrase feels so familiar, even though many people have never actually seen it written down.

Alternatives and Synonyms

If you want to mix up your vocabulary or you’re just unsure whether “per se” fits, here are some solid alternatives depending on context:

• Intrinsically, formal, works well in academic writing
• In itself / in and of itself, natural, conversational alternative
• Inherently, strong substitute in analytical or scientific writing
• As such, useful, though slightly different in nuance
• Strictly speaking, good for softening a claim, similar tone to “per se”

None of these are perfect one-to-one replacements, but they can help you avoid repeating “per se” too often in longer pieces of writing.

Tips to Avoid Confusion

• Remember: “se” is Latin, not English, don’t spell it phonetically.
• Visualize other unchanged Latin phrases like “carpe diem” or “de facto” to reinforce that “per se” follows the same rule.
• When editing, do a quick search for “per say” in your document before submitting anything formal.
• Read your sentence aloud, if you can swap in “in itself” and it still makes sense, “per se” is the correct choice.
