Some -one/-body, etc.

[Rudolph C Troike]

Johanna,

        Thanks for the citation. My own impression is that the -ONE forms
are more formal, the -BODY forms less so. I would be surprised to find
"somebody" in formal writing, but would be equally surprised to hear
"someone" in informal speaking (especially in the South and South Midland;
I can't vouch for other areas). A Lexis/Nexus search might turn up
something, if these are not among the stop-words.
