• Middle English ani bodi. See any, body 1250–1300

Usage

The pronoun anybody is always written as one word:
Is anybody home? There isn't anybody in the office.
The two-word noun phrase any body means "any group'' (Any body of students will include a few dissidents) or "any physical body'':
The search continued for a week despite the failure to find any body.
If the word a can be substituted for any without seriously affecting the meaning, the two-word noun phrase is called for:
a body of students; failure to find a body.
If the substitution cannot be made, the spelling is anybody. Anybody is less formal than anyone. See also anyone, each, they.
