The Genitive Case

Genitive articles, adjective endings, and noun suffixes — the case of possession.

Overview

The genitive case expresses possession — it answers the question "whose?" and corresponds to English "of the" or the possessive "'s."

Das Auto des Mannes ist rot. — The man's car is red. (literally: the car of the man)

Die Tasche der Frau ist neu. — The woman's bag is new.

At B1 level, the genitive is used with:

  • Possession (des, der, eines, einer)
  • Genitive prepositions (wegen, trotz, während, statt)
  • Certain verbs and adjective constructions

This reference covers the article forms, adjective endings, and noun changes in the genitive case.

Definite Articles in Genitive

GenderNominativeGenitiveExample
Masculinederdesdas Auto des Mannes
Femininediederdie Tasche der Frau
Neuterdasdesdas Zimmer des Kindes
Pluraldiederdie Bücher der Kinder

The pattern is straightforward:

  • Masculine and neuter: des
  • Feminine and plural: der

Examples

Die Farbe des Autos gefällt mir. — I like the color of the car.

Der Name der Straße ist lang. — The name of the street is long.

Das Spielzeug des Kindes ist kaputt. — The child's toy is broken.

Die Meinungen der Leute sind verschieden. — The people's opinions are different.

Note: feminine genitive der looks identical to masculine nominative der and feminine dative der — context and the noun ending tell you which case it is.

Indefinite Articles in Genitive

GenderNominativeGenitiveExample
Masculineeineinesdas Büro eines Mannes
Feminineeineeinerdie Stimme einer Frau
Neutereineinesdas Dach eines Hauses
Plural——(no indefinite plural in German)

The pattern mirrors the definite articles:

  • Masculine and neuter: eines
  • Feminine: einer
  • Plural: no indefinite article exists; use the noun alone or "einiger/einiger"

Examples

Das ist das Büro eines Arztes. — That is the office of a doctor.

Ich habe die Stimme einer Frau gehört. — I heard the voice of a woman.

Das Dach eines alten Hauses war beschädigt. — The roof of an old house was damaged.

Adjective Endings in Genitive

This is the simplest rule in all of German adjective declension:

In the genitive case, ALL adjective endings are -en.

It does not matter whether the article is definite, indefinite, or absent. It does not matter whether the noun is masculine, feminine, neuter, or plural. The answer is always -en.

TypeMasculineFeminineNeuterPlural
Definite (des/der)des alten Mannesder alten Fraudes alten Hausesder alten Bücher
Indefinite (eines/einer)eines alten Manneseiner alten Fraueines alten Hauses—

Examples

Die Qualität des deutschen Bieres ist berühmt. — The quality of German beer is famous.

Trotz des schlechten Wetters gehen wir spazieren. — Despite the bad weather, we go for a walk.

Das ist das Haus einer alten Freundin. — That is the house of an old friend (f.).

Wegen der hohen Preise kaufe ich nichts. — Because of the high prices, I'm not buying anything.

Remember: if you are in genitive, the adjective ending is -en. No exceptions.

Noun Suffixes in Genitive

Masculine and neuter nouns add -(e)s in the genitive case. This is a suffix on the noun itself, in addition to the article change.

Rules for -(e)s

Noun typeSuffixExample
One syllableusually -esder Mann → des Mannes, das Buch → des Buches
Multi-syllableusually -sder Lehrer → des Lehrers, das Auto → des Autos
Ending in -s, -ß, -x, -z-esdas Haus → des Hauses, der Platz → des Platzes
Foreign words / names-sdas Restaurant → des Restaurants

Examples

Das Auto des Mannes ist blau. — The man's car is blue. (Mann → Mannes)

Die Seiten des Buches sind gelb. — The pages of the book are yellow. (Buch → Buches)

Der Bruder des Lehrers wohnt in Berlin. — The teacher's brother lives in Berlin. (Lehrer → Lehrers)

Das Dach des Hauses ist rot. — The roof of the house is red. (Haus → Hauses)

Important Exceptions

Feminine nouns do NOT add any suffix in the genitive:

Die Farbe der Blume (not Blumes) — the color of the flower

Plural nouns also do NOT add a suffix:

Die Spielsachen der Kinder (not Kinders) — the children's toys

Weak masculine nouns (n-Deklination) add -n or -en instead of -s:

Der Name des Studenten (not des Students) — the student's name

Die Frage des Kunden — the customer's question

Tips

  1. Genitive articles: des (m/n), der (f/pl) — just two forms to remember.
  2. Adjective endings are ALWAYS -en in genitive — the simplest case for adjectives. No exceptions.
  3. Masculine and neuter nouns add -(e)s — don't forget the noun ending, not just the article.
  4. One-syllable nouns prefer -es, multi-syllable prefer -s — but both are usually acceptable.
  5. Feminine and plural nouns never change in the genitive — only their articles change.
  6. In spoken German, genitive is often replaced by "von + dative" (die Farbe von dem Auto), but in writing and formal speech, genitive is expected at B1 level.
