Questions & Answers about Ich lege meinen Schlüsselbund immer in die obere Schublade.
Because legen is a transitive verb that takes a direct object. In German, direct objects trigger the accusative case. Here Schlüsselbund is masculine singular, so mein (“my”) changes to meinen in the accusative.
German prepositions like in can govern either case depending on the sense of motion versus location:
- Use accusative when expressing movement into something (direction): “in die Schublade” = into the drawer.
- Use dative when expressing a static location inside something: “in der Schublade” = in the drawer (no movement).
Because after the definite article die, adjectives take the weak inflection. For a feminine noun in the accusative, the weak ending is -e. The pattern here is:
die (fem. acc.) + ober (stem) + -e → die obere Schublade.
