How do German possessive pronouns work with noun endings?

They follow the same pattern as ein-words : take the base form like mein or dein and add case, gender, and number endings. For example, mein Hund , meine Katze , meinen Drucker , and meinem Hund .

Why is Ihr so confusing in German?

Because Ihr can mean several things: her , their , or your (formal) , and in some contexts it can also be the pronoun you all . You have to use the context and capitalization to tell them apart: ihr Auto vs. Ihr Auto .

What is special about euer ?

When euer gets an ending, the middle e usually drops: eure , euren , not euere or eueren . This is a common spelling pattern to remember, while unser usually keeps its e in forms like unsere .

Possessive Pronouns — Mine, Yours, Ours 🦞💰

Possessive pronouns indicate ownership (my, your, his). In German, the stem word changes based on who owns the object (mein, dein, sein, ihr), while the ending of the word changes based on the gender and case of the object being owned.

Infographic showing German Possessive Pronouns (my, your, our) indicating ownership.

These pronouns indicate ownership.
They are basically adjectives: "My car", "Your cat".
Because they stand before a noun, they behave exactly like the indefinite article Ein.

1. The Base Forms (Memorize these!) 🧱

English	German Base	Note
I (My)	Mein	Just like English "Mine"
You (Your)	Dein	Rhymes with Mein
He (His)	Sein	-
She (Her)	Ihr	⚠️ Watch out! Same as "You (Plural)"
It (Its)	Sein	Same as He!
We (Our)	Unser	-
You all (Your)	Euer	-
They (Their)	Ihr	-
You (Formal)	Ihr	Capitalized!

[!CAUTION]
The "Ihr" Confusion
Ihr can mean:

Her (Das ist ihr Auto)

Their (Das ist ihr Auto)

You guys (Seid ihr fertig?) - Personal Pronoun

Your (Formal) (Ist das Ihr Auto?)
Context is your only friend here.

2. The Endings (The "Ein" Logic) 🧩

Take the base (Mein) and add the ending from the Ein-words table.

Nominative (Subject)

Masc: Das ist mein Hund. (No ending)
Fem: Das ist meine Katze. (-e)
Neut: Das ist mein Haus. (No ending)
Plural: Das sind meine Kinder. (-e)

Accusative (Direct Object)

Only Masculine changes!

Masc: Ich sehe meinen Drucker. (-en)
Fem: Ich sehe meine Tante. (-e)
Neut: Ich sehe mein Auto. (No ending)

Dative (Receiver)

Masc/Neut: Mit meinem Hund. (-em)
Fem: Mit meiner Mutter. (-er)
Plural: Mit meinen Freunden. (-en)

The "Euer" Trap 🪤

When you add an ending to Euer, the middle "e" runs away because it's lazy.

Euer + e -> Eure (Not Euere)
Euer + en -> Euren (Not Eueren)
Unser is chill, it usually keeps the e (Unsere), but colloquial speech drops it (Unsre).

The Genitive Level 🎩

Yes, Possessive Pronouns also exist in Genitive!
They take the exact same endings as the Genitive Articles (des/der).

Masc/Neut: Das ist das Auto m{ein}es Vaters. (Endings: -es).
Fem/Plural: Das ist das Auto m{ein}er Mutter. (Ending: -er).

If you can handle des/der, you can handle meines/meiner.
