1. Introduction to German Accusative Case

The German accusative case is a crucial aspect of German grammar that every learner should master. It is used to indicate the direct object of a sentence, answering the question ‘whom’ or ‘what’ in relation to the verb. Understanding the accusative case and its declensions will greatly enhance your German language proficiency and open up a world of communication possibilities.

2. When to Use the Accusative Case

In German, the accusative case is used in the following situations:

1. To show the direct object of a sentence: The direct object typically receives the action of the verb and answers the question ‘whom’ or ‘what’. For example: Ich kaufe einen Kuchen (I buy a cake).
2. With certain prepositions: Some prepositions always require the accusative case, such as durch (through), für (for), ohne (without), and um (around). For example: Er geht durch die Tür (He goes through the door).
3. With certain verbs: Some verbs specifically require the accusative case, such as haben (to have), sehen (to see), and lieben (to love). For example: Sie liebt ihren Hund (She loves her dog).
