The idea
Use der Knopf for the nominative singular, den Knopf for the accusative, dem Knopf for the dative, and des Knopfes for the genitive. In the dative plural use den Knöpfen.
| Kasus | Singular | Plural |
|---|---|---|
| Nominativ | der Knopf | die Knöpfe |
| Akkusativ | den Knopf | die Knöpfe |
| Dativ | dem Knopf | den Knöpfen |
| Genitiv | des Knopfes | der Knöpfe |
