CEFR A1 • Nomen und Artikel

Der Kasus: Nominativ und Akkusativ

At CEFR level A1, mastering Nominativ and Akkusativ lets you identify subjects and direct objects correctly and choose the right article form – an essential foundation for all German sentences.

Kernregel: The subject (Nominativ) does the action; the direct object (Akkusativ) receives it. Only masculine articles change: der becomes den, and ein becomes einen. Example: Der Koch kocht die Suppe.

Was ist der Kasus? – What Are Grammatical Cases?

In German, nouns change their form depending on their function in a sentence. This is called case (der Kasus). There are four cases in German, and each one shows a different relationship between words in a sentence.

Important: The case affects the article (der/die/das) and sometimes the noun ending. Learning cases is essential for correct German grammar!

Die vier Fälle – The Four Cases

Case Question Function Example
Nominativ Wer? Was?
(Who? What?)
Subject of the sentence Der Mann liest ein Buch.
Akkusativ Wen? Was?
(Whom? What?)
Direct object Ich sehe den Mann.
Dativ Wem?
(To whom?)
Indirect object Ich gebe dem Mann das Buch.
Genitiv Wessen?
(Whose?)
Possession Das ist das Auto des Mannes.
Note for A1: At this level, we focus mainly on Nominativ and Akkusativ. Dativ and Genitiv will be covered at higher levels.

Der Nominativ – The Nominative Case

Wann benutzen wir den Nominativ?

The Nominativ is used for the subject of a sentence - the person or thing that performs the action. To find the subject, ask: "Wer?" (Who?) or "Was?" (What?) is doing something?

Definite der die das die
Indefinite ein eine ein

💡 Tip: The Nominativ is the "basic form" you find in the dictionary. When you're unsure about the case, Nominativ is often the safe starting point!

Der Akkusativ – The Accusative Case

Wann benutzen wir den Akkusativ?

The Akkusativ is used for the direct object - the person or thing that receives the action. To find the direct object, ask: "Wen?" (Whom?) or "Was?" (What?) is being acted upon?

Artikel im Akkusativ

Maskulin Feminin Neutral Plural
Definite den die das die
Indefinite einen eine ein
Important: Only masculine articles change in Akkusativ: der → den | ein → einen.

Nominativ vs. Akkusativ im Vergleich – Side-by-Side Comparison

die Suppe (Akkusativ) → What does he cook? = The soup (direct object)

einen Schlüssel (Akkusativ) → What does she find? = A key (direct object)

Was bestimmt den Kasus? – What Determines the Case?

B. Präpositionen bestimmen den Kasus
