Somebody vs. Some Body

“Somebody” is a single-word indefinite pronoun meaning an unspecified person. “Some body” is two words only when “some” separately modifies the noun “body,” as in reference to a physical body or other noun sense.

Use “somebody” when you mean “someone.” Use “some body” only when “some” literally modifies the noun “body.”
