- Tony has the same book as I do (He now has my very book).
- Tony has the same book as mine (His book is a copy of my book,it has the same title,written by the same writer).
- Tony's car is the same as mine (Our car are similar, they have a similar model, they are both Fiat 500, for example ).
- Tony drives the same car as me (He is now driving my own car and not a different one).
I'd like to focus your attention on the pattern "same as". We all know that it could mean 1) similar to or 2) identical. My question was how can I understand whether it means "similar" or "identical"? My hypothesis is:
- if the "as" is followed by a objective pronoun, it means "identical, exactly the thing mentioned and not another one".
- if the "as" is followed by a possessive pronoun (mine, yours, theirs, etc.), it means "of the same type, similar".
