German Cases Overview
German cases are four grammatical forms that show a noun's role in a sentence: Nominativ for subjects, Akkusativ for direct objects, Dativ for indirect objects, and Genitiv for possession. Each case changes the article and sometimes the noun ending, such as der Mann, den Mann, dem Mann, des Mannes.
German uses four cases to mark the function of nouns and pronouns in a sentence. The case determines which form of the article and which noun ending to use. Unlike English, where word order primarily shows relationships, German relies on these case markers to clarify who does what to whom.
The Nominativ case marks the subject—the person or thing performing the action. The Akkusativ marks the direct object receiving the action. The Dativ indicates the indirect object, typically the recipient of something. The Genitiv shows possession or close relationships between nouns.
Each case has its own question word: Wer/Was? for Nominativ, Wen/Was? for Akkusativ, Wem? for Dativ, and Wessen? for Genitiv. These questions help identify which case a noun should take. Certain verbs and prepositions also require specific cases regardless of the noun's grammatical role.
Mastering German cases takes practice because you must learn not only the case endings but also which verbs and prepositions govern which cases. The case system affects articles, adjective endings, and pronouns throughout every sentence you build.

- Akkusativ: direct object case
- Akkusativ — direktes Objekt — Wen/Was? (den Mann)
- Dativ: indirect object case
- Dativ — indirektes Objekt — Wem? (dem Mann)
- Genitiv: possessive case
- Genitiv — Besitz — Wessen? (des Mannes)

Examples
Common mistakes
- Using der Mann instead of den Mann after verbs like sehen that require Akkusativ
- Writing dem Kind instead of das Kind when the child is the subject in Nominativ
- Forgetting the Genitiv -s ending and saying des Mann instead of des Mannes
- Confusing Dativ and Akkusativ after prepositions like für, which always takes Akkusativ
FAQ
How do I know which case to use in German?
Identify the noun's role: subject uses Nominativ, direct object uses Akkusativ, indirect object uses Dativ, and possession uses Genitiv. Certain verbs and prepositions also require specific cases, so you must memorize which case each one governs.
Do all German nouns change in every case?
The article always changes with case, but the noun itself only changes in certain situations. Masculine and neuter nouns add -s or -es in Genitiv singular, and Dativ plural nouns add -n if they do not already end in -n or -s.
Is Genitiv still used in spoken German?
Genitiv is less common in everyday speech, where speakers often substitute constructions with von plus Dativ, such as das Auto von dem Mann instead of das Auto des Mannes. However, Genitiv remains standard in formal writing and after certain prepositions.
