Per Say or Per Se? Which Is Correct (And Why Most People Get It Wrong)

You’ve probably seen both versions floating around online. Maybe you’ve typed “per say” in a hurry and moved on. It looks fine. It sounds fine. Yet something about it feels slightly off. That instinct is right. Only one spelling belongs in polished writing and the difference matters more than you might think.

Small language mistakes can quietly damage credibility. They don’t scream. They whisper. A hiring manager notices. A professor circles it. A client pauses for half a second longer than usual. When you write “per se” correctly, you signal precision. When you write “per say,” you signal guesswork. That tiny shift changes how readers perceive you.

So which is correct? Why does the wrong version spread so widely? And how should you actually use the phrase in real sentences without sounding stiff or pretentious? Let’s clear it up once and for all so you can write with confidence every single time.

Per Say or Per Se: Quick Answer

Let’s clear it up fast.

• ✅ Per se is correct.
• ❌ Per say is incorrect.

Per se is a Latin phrase meaning “by itself” or “in itself.”

It sounds like “per say,” which is why so many people spell it that way. However, English kept the original Latin spelling.

Here’s a quick comparison:

Version	Correct?	Meaning	Origin
Per se	✅ Yes	By itself	Latin
Per say	❌ No	None	Misspelling

Simple. Clear. No gray area.

What Does “Per Se” Mean?

At its core, per se means “by itself” or “in isolation.”

When you use it, you separate the thing from surrounding context. You’re saying the issue isn’t the thing alone. The problem lies elsewhere.

Literal Meaning

In Latin:

• Per = through or by
• Se = itself

Together, they form “by itself.”

Modern English Meaning

Today, English uses per se to clarify nuance. It often appears when someone wants to avoid oversimplifying an argument.

For example:

“Social media isn’t harmful per se, but overuse can be damaging.”

Notice the precision. The platform itself isn’t inherently bad. The usage pattern might be.

That subtle distinction matters.

Real-World Examples of Per Se

Let’s look at how it appears across different contexts.

Business Writing

“The strategy isn’t flawed per se, but the execution failed.”

Here, the concept remains sound. The implementation caused the issue.

Academic Writing

“The theory isn’t incorrect per se, but it lacks empirical support.”

Scholarly writing often uses per se to avoid blanket statements.

Everyday Conversation

“It’s not rude per se, just a bit blunt.”

Even casual speech includes it. Though in relaxed settings, “exactly” or “technically” might sound more natural.

Why People Write “Per Say”

This mistake spreads for predictable reasons.

It Sounds Identical

English pronunciation doesn’t reveal spelling. You hear “per say” and write what you hear.

English Rarely Explains Latin Borrowings

English includes thousands of Latin phrases. Many remain unchanged. That creates friction for modern writers.

Autocorrect Confusion

Some older systems don’t recognize per se as a standalone phrase. That can reinforce doubt.

Lack of Formal Grammar Exposure

Many people learn vocabulary through speech rather than reading formal texts. That shapes spelling assumptions.

Other Latin Phrases People Misspell

You’re not alone. Many borrowed expressions cause confusion.

Correct Form	Common Misspelling
Per se	Per say
Bona fide	Bonafied
Faux pas	Fo pa
Ad hoc	Adhock
Vice versa	Vice-versa (hyphen misuse)

Language evolves. However, these spellings remain standardized in formal writing.

How to Use Per Se Correctly in a Sentence

Placement matters.

Most writers place per se after the noun or clause it qualifies.

Correct Structure

• “The policy isn’t illegal per se.”
• “The criticism isn’t personal per se.”

Avoid These Mistakes

• Don’t overuse it.
• Don’t capitalize it mid-sentence.
• Don’t italicize it unnecessarily in modern writing.

Most style guides, including APA and Chicago, no longer require italics for commonly used Latin phrases.

Is Per Se Formal or Informal?

Per se leans formal.

You’ll see it often in:

• Academic journals
• Legal documents
• Analytical essays
• Professional commentary

In casual conversation, simpler alternatives work better.

Instead of:

“It’s not offensive per se.”

You might say:

“It’s not offensive exactly.”

Both communicate clearly. The second feels more natural in relaxed speech.

Per Se in Legal Contexts

Here’s where things get serious.

In law, per se carries weight.

One of the most common phrases is “negligence per se.”

Negligence per se means an act is considered negligent because it violates a statute or regulation. Courts don’t need additional proof of carelessness. The violation itself establishes breach of duty.

For example:

• Running a red light
• Selling alcohol to minors
• Violating workplace safety laws

If someone gets harmed because of that statutory violation, courts may treat it as negligence per se.

This doctrine appears frequently in U.S. case law and tort litigation.

Legal meaning demands precise spelling. Writing “per say” in a legal brief would signal carelessness.

Case Study: When Spelling Damages Credibility

Imagine a law student submits a research paper arguing:

“The defendant’s actions constituted negligence per say.”

Professors would flag it immediately. That tiny spelling error undermines authority.

The same applies in business writing. Clients notice details. Small mistakes create doubt.

Precision builds trust.

Synonyms for Per Se

Sometimes, you don’t need Latin.

Here are alternatives that feel more natural:

• By itself
• In itself
• Inherently
• Intrinsically
• As such
• Technically

Tone Comparison Table

Phrase	Tone	Best Use
Per se	Formal	Legal, academic
By itself	Neutral	Everyday writing
Inherently	Analytical	Essays
Technically	Conversational	Speech

Choose based on audience. Clarity always wins.

Common Mistakes to Avoid

Let’s make this practical.

Writing “Per Say”

It’s incorrect. Always.

Overusing It to Sound Smart

Readers notice forced sophistication. Use it when nuance matters. Skip it when simpler wording works.

Incorrect Capitalization

Lowercase unless starting a sentence.

Unnecessary Italics

Modern usage treats it as naturalized English.

Memory Trick So You Never Misspell It Again

Think of this:

Se = Self

Per se means by itself.

Visualize the word “self” inside “se.” That connection sticks.

Another tip. Remember Spanish reflexive verbs like “se.” That mental link reinforces the spelling.

Pronunciation Guide

Per se is pronounced:

/pər ˈseɪ/

When You Should Avoid Using Per Se

Sometimes, plain English works better.

Avoid it when:

• Writing for younger audiences
• Crafting marketing copy
• Speaking casually
• Trying to simplify complex ideas

For example:

Instead of

“The product isn’t defective per se.”

Say

“The product itself isn’t defective.”

Cleaner. Direct. Easy to read.

Expert Insight

Per se stayed intact because legal and academic communities preserved it.
