The Four Cases

Level 1

German nouns change their 'tags' (articles and endings) depending on whether they are the subject, the direct object, the indirect object, or a possessor.

How It Works

The German case system consists of four distinct roles:

1. Nominativ (Nominative): The subject. This is the person or thing performing the action. It answers the questions Wer? (Who?) or Was? (What?).

2. Akkusativ (Accusative): The direct object. This is the person or thing directly affected by the action. It answers the questions Wen? (Whom?) or Was? (What?). It also follows certain accusative prepositions and indicates direction or destination (Wohin?) with two-way prepositions.

3. Dativ (Dative): The indirect object. This is usually the 'receiver' or beneficiary of an action. It answers the question Wem? (To/for whom?). It is required by specific verbs, dative prepositions, and indicates a static location (Wo?) with two-way prepositions.

4. Genitiv (Genitive): Indicates possession or belonging. It answers the question Wessen? (Whose?). It is used with genitive prepositions like wegen, während, trotz, and statt. In modern spoken German, it is often replaced by von + Dative, but it remains essential in formal writing.

What changes?
The case primarily affects the definite articles, indefinite articles, personal pronouns, possessive determiners, and adjective endings. In some cases, the noun itself changes, such as the Genitive -s, the N-Declension, or the additional -n ending in the Dative plural.

Examples (4)

  1. Der Mann gibt dem Kind den Ball.

    The man gives the ball to the child.

    Word by Word: The man (Nom.) gives the child (Dat.) the ball (Acc.).

    This sentence shows three cases: 'Der Mann' is the subject (Nom.), 'dem Kind' is the receiver (Dat.), and 'den Ball' is the object being moved (Acc.).

  2. Das ist das Auto meines Vaters.

    That is my father's car.

    Word by Word: That is the car (Nom.) of my father (Gen.).

    'Meines Vaters' is in the Genitive case to show that the car belongs to the father.

  3. Ich gehe ohne den Hund in den Park.

    I am going into the park without the dog.

    Word by Word: I go without the dog (Acc.) into the park (Acc.).

    Both 'den Hund' and 'den Park' are Accusative because 'ohne' always takes Accusative, and 'in' indicates movement here.

  4. Er hilft der Frau.

    He helps the woman.

    Word by Word: He helps the woman (Dat.).

    Even though 'the woman' feels like a direct object, the verb 'helfen' is a dative verb and requires the Dative case.

Common Mistakes

  • Using the Nominative for masculine direct objects.

    Ich habe ein Hund.
    Ich habe einen Hund.

    In the Accusative case, only masculine articles change (der -> den / ein -> einen). Learners often forget this specific change.

  • Forgetting the extra -n in the Dative Plural.

    Ich spiele mit den Kinder.
    Ich spiele mit den Kindern.

    In the Dative case, plural nouns must add an -n ending unless they already end in -n or -s.

  • Confusing location (Dative) with movement (Accusative).

    Ich bin in den Supermarkt.
    Ich bin im (in dem) Supermarkt.

    If you are already inside the location (static), you must use the Dative case. Accusative is only for the action of moving toward the destination.
