The genitive case shows possession or relationship between nouns. At B1, the most practical use is genitive prepositions — wegen, trotz, während, and statt — which appear in every official German letter and newspaper article.
You don't need to master all genitive constructions at B1. What you do need: (1) recognize genitive in texts, (2) use the key genitive prepositions correctly, and (3) produce correct genitive in your writing. That's exactly what this guide covers.
| Gender | Definite Article | Indefinite Article | Noun ending |
|---|---|---|---|
| Maskulin | des | eines | adds -(e)s |
| Feminin | der | einer | no change |
| Neutrum | des | eines | adds -(e)s |
| Plural | der | (no article) | no change |
💡 Key pattern: Maskulin and Neutrum nouns add -s or -es in the genitive. Feminin nouns don't change.
In spoken German, people often use von + Dativ instead: "Das Büro von dem Direktor." This is perfectly acceptable in conversation but genitive is expected in formal writing.
These five prepositions always take the genitive case. They appear constantly in formal German:
| Preposition | Meaning | Example |
|---|---|---|
| wegen | because of / due to | Wegen des Regens blieb ich zu Hause. |
| trotz | despite / in spite of | Trotz des Regens gingen wir spazieren. |
| während | during | Während des Gesprächs hat er viel gelernt. |
| statt / anstatt | instead of | Statt des Busses nahm ich die U-Bahn. |
| aufgrund | due to / on account of | Aufgrund der Verspätung verpasste er den Zug. |
| innerhalb | within | Innerhalb eines Monats müssen Sie antworten. |
| außerhalb | outside (of) | Er wohnt außerhalb der Stadt. |
Formal (written): Wegen des Wetters — wegen + Genitiv
Spoken German: Wegen dem Wetter — wegen + Dativ
In the B1 exam Schreiben section, always use the genitive form. In conversation, the dative is common and accepted.
