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

"Stellvertreterpronomen" are replacements for nouns, which keep grammatical gender, case, singular and plural, e.g.:

1. Die Frau hat das Buch dem Mann gegeben. (The woman gave the book to the man.)
2. Sie hat es ihm gegeben. (She gave it to him.)

The same applies for possessive pronouns, e.g.:

1. Das ist mein Auto. (This is my car.)
2. Das ist meines. (This is mine.)

"Begleiterpronomen", however, do not replace a noun but accompany a noun ("begleiten" means to accompany), e.g.:

1. Seine Mutter ist sehr alt. (His mother is very old.)
2. Unser Urlaub war viel zu kurz. (Our vacation was far too short.)
