Genitive Case

Possession and prepositions with genitive (wegen, trotz, statt)

The Genitive case (Genitiv) is used in German to express possession — answering the question 'whose?' — and to follow certain prepositions. Masculine and neuter nouns add the ending -s or -es in the Genitive, while the articles change to des/eines (masculine and neuter) and der/einer (feminine and plural). Although formal written German uses the Genitive regularly, in everyday speech Germans often replace it with von + Dative, so learning both patterns is very useful.

The Genitive case shows possession or belonging.

The Genitive answers the question 'Wessen?' (Whose?). It works like the English apostrophe-s or the phrase 'of the': das Auto des Vaters = the father's car / the car of the father.

Masculine and neuter nouns add -s (or -es) in the Genitive.

Most masculine and neuter nouns add -s: des Mannes → des Manns, des Kindes → des Kinds. Monosyllabic nouns and nouns ending in a sibilant (-s, -sch, -z, -x) usually add -es for ease of pronunciation: des Mannes, des Hauses. Feminine nouns and plurals do not change their noun ending.

Certain common prepositions require the Genitive.

The most important Genitive prepositions at A2/B1 level are: wegen (because of / due to), trotz (despite / in spite of), statt / anstatt (instead of), and während (during). Example: wegen des Regens (because of the rain).

In spoken German, von + Dative often replaces the Genitive for possession.

Instead of 'das Auto meines Vaters' (formal/written), Germans frequently say 'das Auto von meinem Vater' (spoken). Both are correct; knowing this helps you understand native speakers and reduces errors in conversation.

Proper names in the Genitive simply add -s without an apostrophe.

Unlike English, German proper names do not use an apostrophe: Annas Buch (Anna's book), Petersʼ Wohnung is written Peters Wohnung. If a name already ends in -s, -x, or -z, the apostrophe IS used to show possession: Klaus' Auto.

Das ist das Auto meines Vaters.

That is my father's car.

Masculine noun Vater → meines Vaters (Genitive masculine, indefinite possessive article).

Die Tasche der Frau ist sehr teuer.

The woman's bag is very expensive.

Feminine noun Frau → der Frau (Genitive feminine, definite article). Noun ending does not change.

Wegen des schlechten Wetters bleiben wir zu Hause.

Because of the bad weather, we are staying at home.

Genitive preposition wegen + das Wetter (neuter) → des Wetters.

Trotz des Regens gingen sie spazieren.

Despite the rain, they went for a walk.

Genitive preposition trotz + der Regen (masculine) → des Regens.

Statt eines Kuchens hat sie einen Apfel gegessen.

Instead of a cake, she ate an apple.

Genitive preposition statt + der Kuchen (masculine) + indefinite article → eines Kuchens.

Das Spielzeug der Kinder liegt auf dem Boden.

The children's toys are lying on the floor.

Plural noun Kinder → der Kinder (Genitive plural, definite article). Noun ending does not change.

Während des Essens spricht man nicht.

One does not speak during a meal.

Genitive preposition während + das Essen (neuter) → des Essens.

Learn the Genitive articles as a set: des/der/des/der (definite) and eines/einer/eines/– (indefinite). Notice that the feminine and plural definite form is der — the same as the masculine Nominative, so context is key.
When you see a masculine or neuter noun ending in -s or -es in a sentence, check whether a Genitive article (des/eines) is nearby — this is the clearest signal that a Genitive is being used.
For everyday conversation, using von + Dative is perfectly acceptable and sounds natural: das Buch von meiner Schwester instead of das Buch meiner Schwester. Master the Genitive articles first, then practise the formal construction.
Memorise the four most common Genitive prepositions as a group: wegen, trotz, statt, während. They appear frequently in both written and spoken German, especially in news, email, and formal speech.
When writing German, using the Genitive instead of von + Dative makes your text sound more educated and formal. Aim to use it in emails, essays, and formal contexts once you feel comfortable with the article endings.

Forgetting to add -s/-es to masculine and neuter nouns: writing 'das Auto des Vater' instead of 'das Auto des Vaters'. The noun itself must take the Genitive ending, not just the article.
Using Dative articles after Genitive prepositions: writing 'wegen dem Regen' instead of 'wegen des Regens'. Although 'wegen dem' is heard in colloquial speech, in standard written German always use the Genitive after wegen, trotz, statt, and während.
Applying a feminine Genitive ending to the noun: writing 'die Tasche der Frauen' (plural) when meaning 'the woman's bag' (singular). Remember that only masculine and neuter singular nouns change their ending; feminine nouns never do.
Confusing the Genitive der with the Nominative feminine die: 'Das ist die Mutter der Kinder' uses der as the Genitive plural article (the mother of the children), not as the Nominative feminine article. Pay attention to what role the noun is playing in the sentence.
