What Does “Per Se” Mean?
Per se is a Latin phrase that has been adopted into English. It literally means “by itself” or “in itself.”
Writers and speakers use per se when they want to focus on the essential nature of something rather than its related circumstances or effects.
Examples of Per Se
- The idea isn’t wrong per se, but it needs improvement.
- Money isn’t evil per se.
- The product isn’t expensive per se; it’s simply higher quality.
- Working remotely isn’t difficult per se, but it requires discipline.
In each example, the speaker is making a distinction between something’s inherent nature and other factors surrounding it.
What Does “Per Say” Mean?
The phrase per say has no recognized meaning in standard English.
It is simply a misspelling of per se that occurs because the two expressions sound the same when spoken aloud.
Why People Write “Per Say”
Many people learn the expression through conversation rather than reading. Since they hear the pronunciation before seeing the spelling, they naturally assume it is written as per say.
This type of error is sometimes called an eggcorn—a mistake that sounds correct but is actually based on incorrect spelling.
Example
❌ The project wasn’t successful per say.
✅ The project wasn’t successful per se.

How to Use Per Se Correctly
The phrase per se is typically used to clarify that something is not inherently good, bad, right, or wrong.
Common Sentence Pattern

Examples
- The issue isn’t the cost per se; it’s the lack of value.
- The problem isn’t technology per se.
- The criticism wasn’t directed at him per se.
- The food wasn’t unhealthy per se.
This construction helps create a subtle distinction in meaning.

Common Mistakes with Per Se and Per Say
Since the phrases sound identical, mistakes happen frequently.
Mistake 1: Writing Per Say
❌ The plan wasn’t risky per say.
✅ The plan wasn’t risky per se.
This is the most common error.
Mistake 2: Using Per Se Unnecessarily
Some writers use per se simply to sound formal.
❌ I went to the store per se.
✅ I went to the store.
The phrase should only be used when making a distinction about something’s inherent nature.
Mistake 3: Confusing Meaning
❌ The teacher explained the lesson per se.
✅ The teacher explained the lesson clearly.
Not every sentence benefits from adding per se.
Where Did Per Se Come From?
The phrase comes directly from Latin.
In Latin, per se means:
- By itself
- In itself
- Through itself
Over time, English adopted the phrase because it expresses a concept that can be difficult to convey as precisely with a single English expression.
Today, it remains common in:
- Legal writing
- Academic writing
- Journalism
- Business communication
- Everyday conversation
Is Per Se Formal or Informal?
The phrase works in both formal and informal settings.
Formal Examples
- The evidence isn’t conclusive per se.
- The policy isn’t discriminatory per se.
Informal Examples
- I’m not upset per se.
- The movie wasn’t boring per se.
Although it originates from Latin, most English speakers recognize and understand the expression.
American vs British English
The phrase per se is used in both American and British English.
Importantly, the spelling remains exactly the same in both varieties.
American English
- The policy isn’t unfair per se.
- The product isn’t defective per se.
British English
- The policy isn’t unfair per se.
- The product isn’t defective per se.
There is no regional spelling variation.
Why Do So Many People Write “Per Say”?
The mistake occurs because English contains many words that are learned through speech before reading.
When people hear:
“per say”
they naturally assume the second word is say because it matches the pronunciation.
However, the actual spelling comes from Latin:
per se
This makes it similar to other commonly misspelled expressions that sound different from how they are written.
Tips for Remembering the Correct Spelling
A simple memory trick can help.
Think of “Se” as “Self”
Since per se means by itself, connect se with self.
- Per se = by itself
- Per se = in itself
This mental association makes the correct spelling easier to remember.
Remember It’s Latin
If you see per say, ask yourself:
“Does this look like an English phrase?”
Since the expression comes from Latin, the spelling per se makes more sense.
