The Genitive Case (Genitiv) expresses possession, close association, or origin—answering the question Wessen? (“Whose?”). While casual spoken German often bypasses it with von + Dativ, the Genitive remains essential in written German, journalism, professional emails, academic prose, and after key B1–C1 prepositions (wegen, während, trotz, statt).
Genitive Declension Table
| Gender | Definite | Indefinite / Negative / Possessive | Noun Suffix | Example |
|---|---|---|---|---|
| Masculine | des | eines / keines / meines | -(e)s (or -(e)n if weak) |
das Auto des Mannes |
| Feminine | der | einer / keiner / meiner | — (no suffix) | die Tasche der Dame |
| Neuter | des | eines / keines / meines | -(e)s | das Dach des Hauses |
| Plural | der | keiner / meiner | — (no suffix) | die Spielzeuge der Kinder |
Note two crucial facts:
- Feminine and Plural never take
-son the noun—the article (der,einer,meiner) carries the Genitive signal alone. - Adjectives in the Genitive after any article take
-enacross all genders and plural (trotz des schlechten Wetters, wegen einer wichtigen Besprechung). Without an article before a singular masculine/neuter noun, adjectives still end in-en(trotz schlechten Wetters)—only feminine/plural strong adjectives take-er(trotz guter Ergebnisse).
The Noun Suffix Rules: -es vs. -s vs. -(e)n
With masculine and neuter nouns, choosing between -es, -s, and -(e)n follows clear phonological rules:
| Noun Group | Required Suffix | Examples |
|---|---|---|
Ends in -s, -ss, -ß, -x, -z, -tz |
Must take -es |
das Haus → des Hauses · der Platz → des Platzes · der Fluss → des Flusses |
| One-syllable nouns (not ending in sibilant) | -es or -s both valid |
das Buch → des Buches / des Buchs · der Tag → des Tages / des Tags |
Two+ syllables, esp. ending in -en, -er, -el, -chen, -ling |
Take -s only |
der Computer → des Computers · der Wagen → des Wagens · das Mädchen → des Mädchens |
| Weak masculine nouns (N-Declension) | Take -(e)n (NO -s!) |
der Student → des Studenten · der Kollege → des Kollegen · der Herr → des Herrn |
| Mixed nouns (der Name, der Gedanke, das Herz) | Take -ns / -ens |
der Name → des Namens · das Herz → des Herzens |
Proper Names in the Genitive
With personal names or city names, German places the name before the noun (without an apostrophe in standard spelling) and adds -s:
- Annas Buch (Anna’s book) — no apostrophe!
- Lukas’ Fahrrad (if the name ends in
-s, -ß, -x, -z, add an apostrophe alone at the end) - Berlins Museen (Berlin’s museums)
Core Genitive Prepositions & Verbs
Four major B1 prepositions govern the Genitive in standard written German:
- wegen (because of): Wegen des starken Regens bleiben wir zu Hause.
- während (during): Während der Besprechung klingelte das Telefon.
- trotz (despite): Trotz des schlechten Wetters gehen wir wandern.
- statt / anstatt (instead of): Statt eines Autos kaufte er ein Fahrrad.
Note that in everyday speech, people frequently use wegen, während, or trotz with the Dative (wegen dem Regen). In formal writing and exams, keep the Genitive—and see more B2–C1 structures in Genitive Expressions & Functional Noun Groups.
A handful of formal verbs also govern a Genitive object: bedürfen (to require), gedenken (to commemorate), sich erinnern (formal: sich eines Vorfalls erinnern), jemanden einer Sache beschuldigen (to accuse someone of something).
Spoken Alternative: von + Dativ
In daily conversation, German speakers often prefer von + Dative over a Genitive chain, especially when speaking casually or when a noun has no article (like unmodified plurals):
- Written / Standard: das Auto meines Vaters
- Spoken: das Auto von meinem Vater
- Required with bare plurals: der Bau von Wohnungen (because bare plural Wohnungen cannot show Genitive clearly on its own).

Common Mistakes to Avoid
| Mistake | Why It Happens | Correction |
|---|---|---|
| *das Dach des Haus | Changing the article to des but forgetting -es on the noun |
das Dach des Hauses (Sibilant nouns must add -es). |
| *die Tasche der Fraus | Adding -s to a feminine noun |
die Tasche der Frau (Feminine nouns never add -s in the Genitive). |
| *Anna’s Tasche | Using an English possessive apostrophe | Annas Tasche (German only adds an apostrophe after -s/-ß/-z/-x, e.g., Max’ Tasche). |
| *das Büro des Kolleges | Treating an N-declension noun as strong | das Büro des Kollegen (Weak masculine nouns take -n/-en, never -s). |
