He has the same book as I do//mine

[Negij]

Good morning dear all,

1)He has the same book as I do (He now has my very book)
2)He has the same book as mine(His book is a copy of my book,it has the same title,written by the same writer)

Do you think there is any difference betweeen these sentences,I've tried to give a possible explanation,can you tell me whether it is correct?

He has the same book as I do.
He has the same book as me.

His book is the same as my book.
His book is the same as mine.

Would you also say that the following one is also correct?

I bought the same car as yours

 

[emsr2d2]

You'll hear it but I don't like it. I would use "I bought the same car as you [did]". If you want to use "yours", use "My car is the same as yours".

Thank you for yout kind answer,how can I understand whether "same as..."means "similar"or "exactly the thing mentioned"?
Is there a fixed rule?

 

[emsr2d2]

In the context given, it might not mean "exactly the same".

I bought a red Renault Clio. My friend bought a green Renault Clio. She can say "I bought the same car as you", referring to the make and model of the car but of course they are different colours so they are not identical.

Usually, when two things are identical, we use "identical" or "exactly the same".

I initially thought that in "the same... as..."
-if the "as" was followed by a object pronoun it meant "identical,exactly the thing mentioned and not another one".
-if as was followed by a possessive pronoun (mine ,yours,theirs...) it meant "of the same type,similar".
This my initial hypothesis is also clear in my first post.(EDITED)

 

[emsr2d2]

No, it doesn't make any difference what it's followed by.

Would you also agree with this two points
1)What follows the "as" is compared to what is in the subject of the sentence.
2)The meaning of "the same" depends on the context given.

As a last favour ,I'd really appreciate it if I could read some examples where "the same "means similar or exactly the thing/person mentioned.
