Is there any different between someone and Somebody?

There is no real difference between somebody and someone. There is also no difference between anybody and anyone, everybody and everyone or nobody and no one.

When you use the forms with body you are being a little more informal.

Informal…There is somebody at the door. Formal….There is someone at the door.
Informal…Is there anybody at the door? Formal…Is there anyone at the door?
Informal…Nobody is at the door. Formal…No one is at the door.

Thank you!

Basically no difference, yet “Somebody” does take on a more nuanced meaning in “He was a Somebody.” You wouldn’t say, “He was a Someone.”

Thank you :)

I don’t agree with @Carla that the difference is one of formality. I think they’re interchangeable.
