'Big fan of you' vs 'Big fan of yours'

[Tom]

Hi

Could you please tell me the difference:Are both correct?

1- I am a big fan of you.
2- I am a big fan of yours.

1- She is a friend of me.
2- She is a friend of mine.

Hi,

I would go for the possessive forms 'yours' and 'mine'.

A lot of thanks, Alan

Now I would also go for the possessives forms. But may I ask if the other one is informal or incorrect?

Tom

[Alan]

Hi Tom,

Plain wrong, I'm afraid.

Alan, I am simply grateful!

Now, can I deviate a bit from my original post?

1- She is a friend of queen.
2- She is a friend of queen's.

Could you please shed some light on the difference? Which one would you prefer?

Tom

[Alan]

Hi Tom,

Are we talking about a Queen, the Queen or someone called Queen? I also think they all need a capital letter.

If you're talking about a person whose first name is 'Queen', then 2 is correct.

Hi, I've just come across the following sentence: I am a business partner and colleague of Mike. Should't this read I'm a business partner and colleagues of Mike's?

Please let me know what you think.
Regards,
Torsten

Yes, Torsten, you're right -- the possessive is normally used in such constructions: I'm a business partner and colleague of Mike's.

[Alan]

Hi,

Concurring with Conchita but still aware that the saxon genitive form is dying out and its omission here doesn't really offend the ear.

Just as added information, this is called the post-genitive or double genitive. It has some limitations (fide Quirk et. al); for example, the postmodifier must be definite and human: an opera of Verdi's not an opera of a composer's; a hat of my friend's not a funnel of the ship's.
