German Cases Explained Simply: Nominative, Accusative, Dative, Genitive
Nominative, accusative, dative, genitive — explained with logic, not just tables.
German has four cases that change how articles and adjectives look: nominative (subject), accusative (direct object), dative (indirect object), and genitive (possession). Once you understand the logic, the patterns become predictable.
Nominative — Who does the action?
The nominative case marks the subject of a sentence. Der Mann schläft (the man sleeps). Die Frau lacht (the woman laughs). Das Kind isst (the child eats). Articles: der, die, das (familiar from your vocabulary).
Accusative — What is directly affected?
The accusative marks the direct object. Ich sehe den Mann (I see the man). Only masculine "der" changes to "den" — everything else stays the same. Ich liebe die Musik. Ich kaufe das Buch.
Dative — To/for whom?
The dative marks the indirect object or follows certain prepositions (mit, bei, seit, von, nach, aus, zu, gegenüber). Ich gebe dem Mann ein Buch (I give the man a book). All three genders change: dem, der, dem.
Genitive — Whose? (Possession)
Genitive shows possession. Das ist das Haus des Mannes (that is the man's house). Also used after certain prepositions: wegen, trotz, während, statt. Masculine and neuter add -(e)s to the noun.
Memory Trick for Cases
Think of the cases as answering questions: Who? (Nominative) → What/Whom? (Accusative) → To/For whom? (Dative) → Whose? (Genitive). Ask these questions when building a sentence.
