Say it out loud and it sounds like “per say,” so people often spell it wrong. Now you know the truth.
What Does “Per Se” Actually Mean?
When someone says per se, they are focusing on the thing alone, not the situation around it. It isolates the subject so you look at it in its pure form.
Think of it like zooming in on something without background noise.
Meaning In Simple English
- It means “exactly as it is”
- It means “on its own”
- It means “by itself without extras”
Real World Explanation
If someone says:
“The rule isn’t bad per se, it is just misunderstood.”
They are saying:
- The rule alone is not bad
- The problem comes from how people take it or interpret it
So per se lets you make precise statements without sounding confusing.
Origin Of “Per Se” — Where Did It Come From?
“Per se” comes from Latin, a language used historically in law, science, medicine, philosophy, and classical literature. In Latin, it literally means “by itself” or “in itself.”
How It Entered English
- It entered legal English first
- Then spread into academic writing
- Eventually entered everyday conversational English
Even today, English keeps thousands of Latin-based terms such as:
- et cetera (etc.)
- status quo
- vice versa
- per capita
- per annum
“Per se” survived because it expresses something English cannot express as neatly with just one casual phrase.
Why “Per Say” Is Wrong (But So Common)
People hear language before they learn spelling. Since per se sounds exactly like per say, the brain records sound, not letters. Then typing errors follow.
Reasons People Write Per Say
- Phonetic hearing → spelling based on sound
- Limited exposure to proper spelling
- Social media and informal writing
- Lack of grammar education in some schools
- Autocorrect occasionally suggesting wrong options
English has many similar words where pronunciation tricks people:
- “Could of” instead of “could have”
- “Supposably” instead of “supposedly”
- “Definately” instead of “definitely”
“Per say” falls into the same trap. It sounds right but it is wrong in writing.

Everyday Conversation Examples
