Interesting. I always thought [sic] stood for "spelling incorrect".

I see the paper's title but can't find that definition for off-the-record anywhere in the paper; I don't see what "made in confidence and not for publication" has to do with it. I think you nailed the term, but I'm wondering why you have that particular definition in your answer.

What does off-record have to do with it? Edit: I see the wikipedia article equates off-record speech with indirect speech, but your definition of off-record in the question doesn't seem to have anything to do with this meaning.

What do you mean, they can't be used here?

I was always taught that the sentence should still read if you drop either person. i.e. "He is smarter than she" vs. "He is smarter than her".

Shouldn't it be "me and her put together"?
