Possessive

Which do you think are right and why? Your level is presumably above that of your question.

Fair enough. b and d are correct using the possessive determiner, but I'm thinking c, with the possessive pronoun, may also be correct...

c. Tonight is mine and Mary's reunion.

I think "mine" is only a noun, and can't modify "reunion."

You can say, "Tonight is Mary's reunion, tomorrow night is mine."

You can't say "Tonight is mine reunion."

(I trust you'll allow me the comma splice.)

Looking again at c, I agree it is wrong. But I still see it as a possessive pronoun, but one can't say tonight is mine because it is not tonight that one owns. Or are you sticking to your guns, that it is a noun?

Avangi(I trust you'll allow me the comma splice.)

Of course. My writing is usually not devoid of such a petty offence on here either.

In this sense, I didn't mean to distinguish between a noun and a pronoun. Of course it's a pronoun. In either case, it doesn't seem to modify (another) noun very well.

This is my glass; that one is yours.
This is perfectly idiomatic, although you may wish to say something is elipted.

Jane is my date; Sally is yours. (your DATE!) It doesn't mea

I think that with "my date" and "your date," we have possessive adjectives, not pronouns.

That's how I see it. I've read differing views on this over the web...of course. But many sites agree with our labelling of these sentences.
