Questions & Answers about Ich stelle den Papierkorb unter den Schreibtisch.
Why do we use stelle here instead of lege or setze?
The verb stellen means to place something in an upright or standing position. Since a wastebasket (der Papierkorb) has a flat base and stands upright, we use stellen. You would use legen for laying something flat, like a book on its back, and setzen for placing something in a seated position.
Why does unter take den Schreibtisch instead of the dative dem Schreibtisch?
unter is a two-way preposition. When a two-way preposition describes motion towards a new destination, it requires the accusative case. Since you are actively moving the basket to a place under the desk, the masculine noun der Schreibtisch changes to den Schreibtisch. If the basket were already resting there, you would use the dative case.
Both Papierkorb and Schreibtisch take den. Are they both direct objects?
No, they just both happen to be masculine nouns in the accusative case! den Papierkorb is the direct object because it is the thing you are putting. den Schreibtisch is in the accusative case for a completely different reason: the preposition unter forces it into the accusative to show the direction of the movement.
