Anyone and Any One

Commonly Confused Words

Anyone vs. Any One

Is anyone (or any one) spelled as one word or two? The answer depends on how the word or phrase is used. The space between two words makes a difference.
 

Definitions

The indefinite pronoun anyone (one word) refers to any person at all but not to particular individuals.

Any one (two words) is an adjective phrase that refers to any single member of a group (of either people or things). Any one is commonly followed by the preposition of.

A similar distinction applies to anybody and any body, nobody and no body.

    Usage Note

    "[W]hat's the difference between anyone and any one? Or between everyone and every one? First, they are all grammatically singular, regardless of meaning. But there is a difference in meaning between the one- and two-word versions: when you type anyone or everyone, you're referring to people; when you type any one or every one you may be referring to people, but not necessarily--it depends on what follows or what is understood.

    "For example, perhaps you mean 'any one of the customers' or 'every one of the customers' (in which case you are referring to people); or maybe you mean 'any one of the petunias' or 'every one of the petunias' (in which case you are not referring to people). In sum, any one and every one mean one of a group (of people or things), rather than one person (anyone) or a bunch of people (everyone)."
