Or: "Paul's threatening behaviour" = "The threatening behaviour of Paul"
But sometimes, we don't say "of Paul", we say "of Paul's".
"He is a friend of Paul's". Of Paul's what?
I don't feel this can be just another version of "He is a friend of
Paul" with an apostrophe-s tacked onto it for some reason, but is in
effect "He is one of Paul's friends", i.e. "He is a member of the
collection of Paul's friends".
What is the history of this formation?
