The confusion between anyone vs any one is easy to understand. The two forms sound the same and look almost the same, but they are not used the same way.
Anyone means any person.
Does anyone know?
Any one means any single one from a group.
Choose any one of these.
This is not just a spelling choice. The space changes the grammar and the meaning. Once you know what each form points to, the choice becomes simple.
Quick Answer
Use anyone when you mean any person.
Anyone can join.
Does anyone have a question?
Use any one when you mean any single one from a group.
Any one of the books is fine.
You may choose any one of these seats.
The phrase any one can refer to people or things. It does not only refer to people.
Why People Confuse Them
People confuse these forms because they have the same pronunciation. They also have nearly the same letters.
Both forms can appear in sentences about people:
Can anyone help?
Can any one of you help?
The first sentence asks whether any person can help. The second sentence points to one person from a specific group.
The written choice depends on meaning and sentence structure, not sound.
