highschool or high school

If you’ve ever wondered whether to write highschool or high school, you’re definitely not alone.

Although they look similar, only one of them is grammatically correct, and they serve completely different roles in writing.

In this easy, friendly guide, you’ll learn what each version means, how to use them, real-life examples, a comparison table, common mistakes, and simple ways to avoid confusion forever. Let’s dive in! 🎓✨


What Is “High School”? (Correct Form)

High school (two words) is the correct and official spelling recognized worldwide. It refers to the educational institution students attend after middle school and before college. In many countries, high school includes grades 9 to 12, though the structure varies.

How “High School” Is Used

  • As a noun:
    “I go to high school.”
  • As an adjective:
    “She is a high school teacher.”

Why It Is Written as Two Words

“High” describes the level of schooling, while “school” identifies the type of institution. Together, they form a clear and grammatically correct phrase.

Where You’ll See It

  • Government education websites
  • School forms and documents
  • News articles
  • Academic writing
  • Professional communication

In simple terms: “High school” is correct, formal, and universally accepted.


What Is “Highschool”? (Incorrect Form)

Highschool (one word) is not grammatically correct in standard English. Even though it sounds like one word when spoken, dictionaries and educational institutions do not accept it as proper spelling.

Where “Highschool” Commonly Appears

  • Casual conversations
  • Social media posts
  • Usernames (e.g., HighschoolVlogs)
  • Misprints
