In English, possessive adjectives like my, your, or his stay exactly the same no matter what noun follows them. You say "my dog," "my car," "my sister" — the word my never changes.

German works differently. Possessive articles — also called possessive determiners — must agree with both the owner (who possesses the thing) and the noun being possessed (its gender and case). That sounds like a lot to juggle, but there is a clean two-step system that makes it manageable.

At A1 level, you need to handle the Nominative (subject) and Accusative (direct object) cases. Master those and you have the foundation for everything else.

Step 1 — Identify the Owner

Every personal pronoun has its own possessive base. Think of the base as the root word — it tells you who owns something. Nothing is attached to the end yet; that comes in Step 2.

Personal Pronoun English Possessive Base
ich I mein-
du you (informal singular) dein-
er he sein-
sie she ihr-
es it sein-
wir we unser-
ihr you (informal plural) euer-
sie / Sie they / you (formal) ihr- / Ihr-
Watch out: ihr (lowercase) has two jobs — it means "her" (she → ihr) and "their" (they → ihr). The capitalised Ihr is the formal "your." Context and capitalisation are your guides.

Step 2 — Add the Ending (Nominative)

Once you know the possessive base, you attach an ending that reflects the gender of the noun being possessed. In the Nominative case — where the possessive article introduces the subject of the sentence — the rule is simple:

Masculine & Neuter (der / das) no ending Add nothing to the base. The base form stands alone.

mein Hund (my dog — masculine)
mein Auto (my car — neuter)

Feminine & Plural (die / die) + e Add -e to the base.

meine Katze (my cat — feminine)
meine Kinder (my children — plural)

Here are those rules in action with the full set of owners:

Owner Masculine (der) Neuter (das) Feminine (die) Plural (die)
ich mein mein meine meine
du dein dein deine deine
er / es sein sein seine seine
sie (she) ihr ihr ihre ihre
wir unser unser unsere unsere
ihr (you pl.) euer euer eure eure
sie / Sie (they / formal you) ihr / Ihr ihr / Ihr ihre / Ihre ihre / Ihre
Tip: Notice that masculine and neuter take the same form (no ending), and feminine and plural also share the same form (-e). You only need to remember two shapes per owner, not four.

The Accusative Case — One Change Only

When the owned noun is the direct object of the sentence (receiving the action), you are in the Accusative case. The good news: almost nothing changes from the Nominative.

There is exactly one difference: masculine nouns take the ending -en instead of no ending. Feminine, neuter, and plural stay identical to their Nominative forms.

Gender Nominative (Subject) Accusative (Direct Object)
Masculine (der) mein Hund meinen Hund
Neuter (das) mein Auto mein Auto
Feminine (die) meine Katze meine Katze
Plural (die) meine Kinder meine Kinder

Compare the two cases in real sentences:

Case German English
Nominative Mein Bruder ist hier. My brother is here.
Accusative Ich sehe meinen Bruder. I see my brother.
Nominative Dein Hund schläft. Your dog is sleeping.
Accusative Du kaufst deinen Hund. You are buying your dog.
Memory trick: The Accusative only ever changes masculine nouns — and you will already recognise this from definite articles (der → den). Possessive articles follow exactly the same pattern: just add -en to the masculine base.

Spelling Exceptions: euer and unser

Two possessive bases need a little extra attention when endings are added to them.

euer — you (plural) euer → eur- When euer gets an ending, the middle e drops out.

euer Hund (masc.) — no ending, no change
eure Katze (fem.) — the inner e disappears
euer Auto (neut.) — no ending, no change
euren Hund (masc. acc.) — inner e drops
unser — we unser → unser- unser follows the standard rules without any letter dropping.

unser Hund (masc.) — no ending
unsere Katze (fem.) — add -e
unser Auto (neut.) — no ending
unseren Hund (masc. acc.) — add -en
The key difference: euer loses its inner e whenever a suffix is added (eure, euren). unser keeps all its letters and simply adds the standard ending.

Full Cheat Sheet — Nominative & Accusative

Here is the complete reference table for all owners across both cases. Drag or scroll horizontally on smaller screens. The only Accusative changes are the masculine column — highlighted in red.

NOMINATIVE (subject)

Owner Masculine (der) Neuter (das) Feminine (die) Plural (die)
ich mein mein meine meine
du dein dein deine deine
er / es sein sein seine seine
sie (she) ihr ihr ihre ihre
wir unser unser unsere unsere
ihr (you pl.) euer euer eure eure
sie / Sie ihr / Ihr ihr / Ihr ihre / Ihre ihre / Ihre

ACCUSATIVE (direct object) — only masculine changes

Owner Masculine (den) ← changes Neuter (das) Feminine (die) Plural (die)
ich meinen mein meine meine
du deinen dein deine deine
er / es seinen sein seine seine
sie (she) ihren ihr ihre ihre
wir unseren unser unsere unsere
ihr (you pl.) euren euer eure eure
sie / Sie ihren / Ihren ihr / Ihr ihre / Ihre ihre / Ihre

Fill in the possessive article

Type the full possessive article (e.g. mein, deine, seinen) — check the gender and case hint if you need a nudge.

  1. 1 Das ist Bruder.
    (ich → mein- · masculine · Nominative) — That is my brother.
  2. 2 Ist das Katze?
    (du → dein- · feminine · Nominative) — Is that your cat?
  3. 3 Er liebt Hund.
    (er → sein- · masculine · Accusative) — He loves his dog.
  4. 4 Das ist Auto.
    (wir → unser- · neuter · Nominative) — That is our car.
  5. 5 Wo ist Mutter?
    (ihr plural → euer- → eure · feminine · Nominative) — Where is your mother?

Study Tips

Three habits that will make possessive articles feel automatic faster than you expect.

  • 1 Learn nouns with their gender from the start. You cannot pick the right possessive article ending without knowing whether a noun is der, die, or das. Write every new noun with its article — der Hund, never just Hund.
  • 2 Memorise the two-cell rule for Nominative. Masculine and neuter = no ending. Feminine and plural = -e. Once that reflex is automatic, all seven owners fall into the same pattern.
  • 3 For Accusative, only watch the masculine. Every time you write a sentence with a direct object, ask: "Is this masculine?" If yes, add -en. If not, write exactly what you would in the Nominative. That single check covers all the Accusative changes you need at A1.
