Everyone vs. Every One: What's the Difference?

Quick Answer

everyone = pronoun meaning "everybody" / all people

every one = emphasizes each individual person or thing (often + "of")

Explanation

EVERYONE (one word)

Pronoun = everybody, all people

"Everyone loved the movie."

"Has everyone arrived?"

EVERY ONE (two words)

Each individual one — often followed by "of"

"Every one of the boxes was checked."

"I read every one of his books."

Quick test: Can you replace it with "everybody"? Use everyone. Is it followed by "of" or emphasizing each individual item? Use every one.

    Every one; Everyone

    Use every one of for the individual books. Everyone refers to the people, and both constructions take singular agreement here.
