German has four grammatical cases: Nominativ, Akkusativ, Dativ, and Genitiv. Each one tells you the role a noun plays in a sentence — who’s doing the action, who’s receiving it, who it’s being done for, and who owns what. Once you can spot which case a noun is in, German word order and articles stop feeling random and start following a fixed, learnable pattern.
The 4 cases at a glance
| Case | Role | Question word | Example |
|---|---|---|---|
| Nominativ | Subject (who/what is acting) | Wer? / Was? | Der Mann liest ein Buch. |
| Akkusativ | Direct object (who/what is affected) | Wen? / Was? | Ich sehe den Mann. |
| Dativ | Indirect object (to/for whom) | Wem? | Ich gebe dem Mann ein Buch. |
| Genitiv | Possession (whose) | Wessen? | Das Auto des Mannes. |
The fastest way to identify a case: ask the question word
This is the single most useful trick for German cases. Take the verb in your sentence and ask:
- Wer/Was…? (Who/what is doing this?) → the answer is Nominativ
- Wen/Was…? (Whom/what is affected?) → the answer is Akkusativ
- Wem…? (To/for whom?) → the answer is Dativ
- Wessen…? (Whose?) → the answer is Genitiv
Example: Ich gebe dem Mann ein Buch. Ask “Wer gibt?” → ich (Nominativ). Ask “Wem gebe ich?” → dem Mann (Dativ). Ask “Was gebe ich?” → ein Buch (Akkusativ). Three questions, three cases, instantly identified.
The definite article table (der, die, das) across all 4 cases
This is the core table to memorize — everything else builds on it.
| Case | Masculine | Feminine | Neuter | Plural |
|---|---|---|---|---|
| Nominativ | der | die | das | die |
| Akkusativ | den | die | das | die |
| Dativ | dem | der | dem | den |
| Genitiv | des | der | des | der |
Notice: only two things really change across the whole table — masculine goes der → den → dem → des, and everything else shifts far less. That’s a much smaller memorization task than it first looks like.
The indefinite article table (ein, eine) across all 4 cases
| Case | Masculine | Feminine | Neuter | Plural (kein/mein…) |
|---|---|---|---|---|
| Nominativ | ein | eine | ein | keine |
| Akkusativ | einen | eine | ein | keine |
| Dativ | einem | einer | einem | keinen |
| Genitiv | eines | einer | eines | keiner |
(ein itself has no plural form — the plural row only applies to ein-words that do have a plural, like kein, mein, dein.)
Nominativ — the subject
The Nominativ case marks the subject: the person or thing performing the action, or the noun linked by verbs like sein, werden, and bleiben.
Der Mann liest ein Buch. (The man is reading a book.) Sie ist Lehrerin. (She is a teacher.)
Akkusativ — the direct object
The Akkusativ case marks the direct object — what’s directly affected by the action.
Ich sehe den Mann. (I see the man.)
Common Akkusativ verbs: haben, sehen, kaufen, suchen, brauchen, essen, trinken, lesen, finden.
Prepositions that are always Akkusativ: durch, ohne, gegen, für, um (remember these with the mnemonic DOGFU).
For the full picture of which verbs and prepositions take Akkusativ vs. Dativ — including tricky fixed expressions like sprechen über — see our guide on German verbs with prepositions: Akkusativ or Dativ.
Dativ — the indirect object
The Dativ case marks the indirect object — usually the person receiving or benefiting from something.
Ich gebe dem Mann ein Buch. (I give the man a book.)
Common Dativ verbs: helfen, danken, gefallen, gehören, glauben, folgen, gratulieren, antworten.
Prepositions that are always Dativ: aus, außer, bei, mit, nach, seit, von, zu.
Genitiv — possession
The Genitiv case shows ownership or a relationship between two nouns — the German equivalent of English’s “‘s” or “of the.”
Das Auto des Mannes. (The man’s car.)
Genitiv is less common in casual spoken German (many speakers replace it with “von + Dativ” — von dem Mann instead of des Mannes) but it’s still expected in writing and formal speech, and prepositions like während, trotz, wegen, and statt still require it.
Important detail: masculine and neuter nouns add -s or -es in the Genitiv (des Mannes, des Kindes) — this is one of the most common mistakes learners make, since it’s easy to forget the noun itself changes, not just the article.
How case affects adjective endings
Once an adjective is added before the noun, its ending also changes based on the case — following the strong, weak, or mixed declension pattern. If you want the full breakdown with tables for each pattern, see German adjective declension: strong, weak, and mixed.
Personal pronouns in all 4 cases
| Nominativ | Akkusativ | Dativ | English |
|---|---|---|---|
| ich | mich | mir | I / me |
| du | dich | dir | you |
| er | ihn | ihm | he / him |
| sie | sie | ihr | she / her |
| es | es | ihm | it |
| wir | uns | uns | we / us |
| ihr | euch | euch | you (plural) |
| sie | sie | ihnen | they / them |
| Sie | Sie | Ihnen | you (formal) |
Pronouns show the case even more clearly than articles: Ich sehe ihn (Akkusativ) vs. Ich helfe ihm (Dativ). See accusative pronouns and dative pronouns.
Which case do prepositions take?
| Case | Prepositions |
|---|---|
| Akkusativ | durch, für, gegen, ohne, um |
| Dativ | aus, bei, mit, nach, seit, von, zu, gegenüber |
| Akkusativ or Dativ (two-way) | an, auf, hinter, in, neben, über, unter, vor, zwischen |
| Genitiv | wegen, trotz, während, statt |
The two-way prepositions take Akkusativ for movement (Wohin?) and Dativ for position (Wo?): Ich gehe in den Park vs. Ich bin in dem (im) Park. Full guide: Lokalpräpositionen.
Which case does the verb take?
Most German verbs take a direct object in the Akkusativ. A small, fixed group takes the Dativ, and “giving” verbs take both.
| Pattern | Verbs | Example |
|---|---|---|
| Akkusativ (most verbs) | haben, sehen, brauchen, kaufen, lieben, finden, besuchen | Ich habe einen Bruder. |
| Dativ | helfen, danken, gefallen, gehören, antworten, glauben, gratulieren, folgen, passen, schmecken | Ich helfe dem Mann. |
| Dativ (person) + Akkusativ (thing) | geben, schenken, zeigen, schicken, erklären, bringen | Ich gebe dem Kind einen Ball. |
Is haben Akkusativ or Dativ?
Akkusativ. Haben takes a direct object: Ich habe einen Hund, Hast du einen Stift? The same applies to es gibt — see es gibt + Akkusativ.
Verbs with prepositions decide the case themselves
When a verb comes with a fixed preposition, the preposition decides the case:
| Verb + preposition | Case | Example |
|---|---|---|
| Angst haben vor | Dativ | Ich habe Angst vor dem Hund. |
| träumen von | Dativ | Ich träume von einem Urlaub. |
| warten auf | Akkusativ | Ich warte auf den Bus. |
| denken an | Akkusativ | Ich denke an dich. |
| sich freuen auf | Akkusativ | Ich freue mich auf das Wochenende. |
These have to be learned as a unit — the full list is in German verbs with prepositions: Akkusativ or Dativ.
Dativ or Akkusativ? The 3-step test
- Is there a preposition? Let the preposition decide (table above).
- Is it a Dativ verb (helfen, danken, gefallen…)? → Dativ.
- Otherwise, the direct object is Akkusativ. If the verb has two objects, the person is usually Dativ and the thing Akkusativ.

Common mistakes with German cases
- Using Nominativ where Akkusativ is required. Ich sehe der Mann ❌ → Ich sehe den Mann ✅ — this is one of the most frequent beginner errors, since der looks “default” but the verb sehen needs Akkusativ.
- Mixing up Akkusativ and Dativ after two-way prepositions, where the case depends on movement vs. location.
- Forgetting the -s/-es ending on masculine and neuter nouns in Genitiv (des Mannes, not des Mann).
