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.”
Key details
Choose the right form
| Meaning / grammatical role | Form | Decision |
|---|---|---|
| an unspecified person | somebody | Use the one-word indefinite pronoun. |
| “body” is an independent noun and “some” determines that noun phrase | some body | Use two words only when the ordinary noun “body” is genuinely present. |
| “someone” can replace the expression without changing the role | somebody | The substitution test points to the pronoun. |
Quick tests
Meaning / construction test
Can “someone” replace the expression while keeping the intended meaning?
If yes: Use “somebody.”
If no: If “body” is functioning as the actual noun, keep “some” and “body” separate.
Caveat: Do not split the pronoun merely because its historical parts are recognizable; the spaced form needs an independent noun “body.”
Examples
Somebody left a package at the front desk.
“Somebody” is the pronoun for an unspecified person.
We need somebody who can check the figures.
“Someone” could replace the expression, so the one-word pronoun is appropriate.
When you mean an unspecified person, keep somebody as one word.
The one-word form is the standard pronoun; two words belong to a different noun-phrase structure.
Further guidance
