What's the difference between "everyone" and "every one"?
"Everyone" is a pronoun: it refers to all of the people who you are talking about.
In the two words, "every one," "every" is an adverb that answers the question, "How many?" "One" is a pronoun. "Every one" can refer to either people or things. It also means "all." "Every one" is almost always followed by a prepositional phrase that describes the group that you are talking about.
