Possessive pronoun, how to use them as “Stellvertreter” vs. “Begleiter”?

Question

I am learning about Possessivpronomen few days now, but there is one thing confusing me.

When I am looking at the table, I see Begleiter possessive pronouns and Stellvertreter possessiv pronouns.

I understand that I need to use a Begleiterpossessivpronomen in front of a noun, but I dont understand, when I need to use Stellvertreterpossessivpronomen?

Can you please explain me when I use a Stellvertreter?

Answer 1

I just realized the answer.

Die (meisten) Pronomen dienen als Platzhalter oder Stellvertreter für ein Nomen. ^Canoo.net

I use a Begleiterpossesivpronomen with the noun, and a Stellvertreterpossesivpronomen without a noun!

Dies ist mein Auto - Dieses Auto ist meines

So simple!
