German Cases
German has four cases: nominative (subject), accusative (direct object), dative (indirect object), and genitive (possessive). They make each noun's role clear by changing it's article endings and sometimes the noun ending, which allows for a flexible word order.
Indefinite Article Declension
The indefinite articles (ein, eine) and negative article (kein) follow this pattern. Depending on the case, gender and number, the ending changes:
| Case | Masculine | Feminine | Neuter | Plural (kein only) |
|---|
| Nominative | (k)ein | (k)eine | (k)ein | keine |
| Accusative | (k)einen | (k)eine | (k)ein | keine |
| Dative | (k)einem | (k)einer | (k)einem | keinen |
| Genitive | (k)eines | (k)einer | (k)eines | keiner |
Definite Article Declension
The definite articles (der, die, das) also change form according to case. The male accusative as well as all the dative and genitive declensions have the same endings as the indefinite articles.
| Case | Masculine | Feminine | Neuter | Plural |
|---|
| Nominative | der | die | das | die |
| Accusative | den | die | das | die |
| Dative | dem | der | dem | den |
| Genitive | des | der | des | der |
Noun Endings in Different Cases
While articles show most case changes, nouns only change their endings in a few cases:
| Case | Masculine | Feminine | Neuter | Plural |
|---|
| Nominative | der Mann | die Frau | das Kind | die Kinder |
| Accusative | den Mann | die Frau | das Kind | die Kinder |
| Dative | dem Mann | der Frau | dem Kind | den Kindern |
| Genitive | des Mannes | der Frau | des Kindes | der Kinder |
There is a small group of masculine nouns called weak nouns which add -n or -en to all forms except nominative. You can learn more about them here.
