The Genitive Case | German Grammar

The genitive is German's case of possession and relation — it answers the question wessen? ("whose?") and translates the English possessive 's or the word of: das Auto des Mannes (the man's car / the car of the man), die Farbe der Wand (the color of the wall). It is the fourth and rarest of the German cases, and in everyday speech it is steadily yielding ground to a von + dative construction. But it remains fully alive in writing, in fixed phrases, and after a set of prepositions, so a B1 learner needs to recognize and produce it.

What the genitive does

At its core the genitive links two nouns, where one belongs to, derives from, or is a property of the other. The genitive noun is the possessor; the noun it attaches to is the thing possessed.

Das ist das Auto des Mannes.

That's the man's car. — des Mannes marks the possessor

Die Farbe der Wand gefällt mir nicht.

I don't like the color of the wall. — der Wand, feminine genitive

Der Titel des Buches ist sehr lang.

The title of the book is very long. — des Buches, neuter genitive with -es

The article forms

The genitive endings on the definite article are easy to confuse with the dative, so learn them as a block. The masculine and neuter both take des; the feminine and plural both take der.

	Masculine	Neuter	Feminine	Plural
Definite	des	des	der	der
Indefinite	eines	eines	einer	— (keiner, meiner…)
Example	des Mannes	des Kindes	der Frau	der Kinder

Notice that der appears in both the feminine genitive (der Frau) and the plural genitive (der Kinder) — context and the noun's number tell them apart.

The critical noun rule: masculine and neuter add -(e)s

This is the rule English speakers most often forget. In the genitive singular, masculine and neuter nouns take an ending of their own: -s or -es. Feminine nouns and all plurals add nothing.

Masculine / neuter singular → add -(e)s: des Mannes, des Tages, des Hauses, des Kindes, des Autos.
Feminine singular → no ending: der Frau, der Stadt, der Liebe.
Plural (any gender) → no ending: der Kinder, der Männer, der Häuser.

When do you add -s versus -es? Use -es after a single syllable or a word ending in -s, -ß, -z, -x, -tz (des Hauses, des Tages, des Platzes), and -s after longer words and most words ending in a vowel or -el/-er/-en (des Autos, des Lehrers, des Wagens). Both are correct for many one-syllable words (des Tags / des Tages), with -es sounding slightly more careful.

Das Dach des Hauses ist undicht.

The roof of the house is leaky. — neuter, -es after -s

Am Ende des Tages zählt nur die Gesundheit.

At the end of the day, only health matters. — masculine, des Tages

Die Meinung der Lehrerin war eindeutig.

The teacher's opinion was clear. — feminine, no ending: der Lehrerin

💡

The hidden trap: the noun changes, not just the article. English only changes one word ("the man's"), so learners write "des Mann." German changes both: des Mannes. Train yourself to add the noun ending automatically for masculine and neuter.

Word order: the genitive follows the noun

In English the possessor comes before the thing possessed: "my parents' house," "the company's profits." In German the genitive normally comes after the noun it modifies:

Das ist das Haus meiner Eltern.

That's my parents' house. — meiner Eltern follows Haus

Die Gewinne des Unternehmens sind gestiegen.

The company's profits have risen. — des Unternehmens follows Gewinne

Saying meiner Eltern Haus (mirroring English word order) sounds archaic or poetic and is wrong in normal modern German. The default is firmly noun-first, genitive-second.

The one exception: proper names take a pre-posed -s

There is exactly one productive place where German puts the possessor first, English-style: proper names. A personal name (or a name used like one) takes a simple -s with no apostrophe and stands before the noun:

Das ist Annas Buch.

That's Anna's book. — name + -s, pre-posed, no apostrophe

Wir fahren mit Peters Auto.

We're taking Peter's car. — Peters before Auto

Münchens Innenstadt ist immer voll.

Munich's city center is always crowded. — place name as possessor

This is the only native pattern where the genitive precedes its noun. Common nouns cannot do it: you cannot say des Mannes Auto in normal German — it must be das Auto des Mannes. So the rule splits cleanly: proper names → pre-posed -s (Annas Buch); common nouns → post-posed des/der (das Buch der Frau).

💡

Two systems, never mixed: a name acts like English ("Annas Buch"). A common noun with an article stays behind its head noun ("das Buch des Mannes"). If there's a der/die/das, the genitive goes after.

Names ending in a sibilant: just an apostrophe

When a name already ends in an s-sound (-s, -ß, -z, -x), you cannot add another -s. Instead, modern German writes a bare apostrophe:

Das ist Max' Fahrrad.

That's Max's bike. — Max' with apostrophe only, no extra -s

Hast du Hans' Adresse?

Do you have Hans's address? — Hans' with apostrophe

In speech these are indistinguishable from the base name; the apostrophe only matters in writing. (Many speakers sidestep the issue entirely with das Fahrrad von Max.)

Partitive and other relational uses

The genitive also expresses the "of" in quantities and abstract relations:

Trotz des Lärms konnte ich gut schlafen.

Despite the noise, I slept well. — genitive after the preposition trotz

Die Hälfte des Kuchens ist schon weg.

Half of the cake is already gone. — partitive genitive: des Kuchens

(The genitive after prepositions like trotz and wegen is covered in detail on the genitive prepositions page.)

How this differs from English

English has two ways to show possession — the clitic 's ("the dog's bowl") and the of-phrase ("the bowl of the dog") — and both keep the possessed noun's form unchanged. German's genitive does three things English does not: it changes the article (des/der), it adds an ending to the masculine/neuter noun itself (des Mannes), and it puts the possessor after the head noun by default. The pre-posed name pattern (Annas Buch) is the one familiar island. Everything else requires un-learning the English instinct to lead with the possessor.

Common Mistakes

❌ Das ist das Auto des Mann.

Incorrect — masculine genitive noun must take -(e)s: des Mannes.

✅ Das ist das Auto des Mannes.

That's the man's car. — des Mannes.

❌ Das ist meiner Eltern Haus.

Incorrect — common-noun genitive can't be pre-posed English-style.

✅ Das ist das Haus meiner Eltern.

That's my parents' house. — genitive follows the noun.

❌ Das ist Anna's Buch.

Incorrect — German names take -s with no apostrophe (the apostrophe is an English import).

✅ Das ist Annas Buch.

That's Anna's book. — no apostrophe before the -s.

❌ Die Farbe des Wand gefällt mir.

Incorrect — Wand is feminine, so the article is der, not des.

✅ Die Farbe der Wand gefällt mir.

I like the color of the wall. — feminine genitive der Wand.

❌ Das ist Maxs Fahrrad.

Incorrect — a name ending in -s takes only an apostrophe, not another -s.

✅ Das ist Max' Fahrrad.

That's Max's bike. — Max' with apostrophe only.

Key Takeaways

The genitive marks possession and relation (wessen?), translating English 's and of.
Articles: des (masc./neut.), der (fem./plural).
Masculine and neuter singular nouns add -(e)s: des Mannes, des Hauses. Feminine and plural add nothing.
The genitive normally follows its noun (das Haus meiner Eltern); only proper names are pre-posed with -s (Annas Buch).
Names ending in -s/-ß/-z/-x take only an apostrophe (Max' Buch).
