How many cases does German have?

German has four grammatical cases: Nominativ (subject), Akkusativ (direct object), Dativ (indirect object), and Genitiv (possession or relationship). Each case signals the grammatical role of the noun in the sentence. The case controls the article form, pronoun form, and — at B1 level — adjective endings too.

Which case is the hardest to learn?

Most learners find Dativ hardest, because it involves both article changes (all four genders shift) and a list of verbs that take Dativ instead of Akkusativ — those must be learned individually. Genitiv feels unfamiliar because English uses "of" or apostrophe-s rather than a case ending. Akkusativ is the easiest entry point: only the masculine article changes (der → den), everything else stays the same.

Do all German verbs take the same case?

No. Most transitive verbs take Akkusativ for their direct object, but a fixed set take Dativ: helfen, danken, glauben, folgen, gehören, gefallen, antworten, vertrauen. A small number take Genitiv, though this is rare in modern spoken German. Prepositions also govern specific cases — Akkusativ (durch, für, gegen, ohne, um) or Dativ (aus, bei, mit, nach, seit, von, zu) — and learning them together with their case is the most efficient approach.

Is Genitiv dying out in German?

In everyday spoken German, Dativ increasingly replaces Genitiv — you will hear "wegen dem Wetter" far more than "wegen des Wetters" in casual speech. But Genitiv is alive in written German, formal speech, journalism, and exams. At A2–B1 level the right approach is: learn to recognise Genitiv when you read it, and produce it in writing. Avoiding it entirely in speech is fine; avoiding it in formal writing is a noticeable register mistake.

How do prepositions affect cases?

Every German preposition locks its object into a specific case. Pure Akkusativ prepositions: durch, für, gegen, ohne, um. Pure Dativ prepositions: aus, bei, mit, nach, seit, von, zu, gegenüber. Two-way prepositions (an, auf, hinter, in, neben, über, unter, vor, zwischen) take Akkusativ when expressing movement toward a destination and Dativ when expressing location or rest. The movement-vs-location distinction — "Ich lege das Buch auf den Tisch" (Akk) vs "Das Buch liegt auf dem Tisch" (Dat) — is one of the most tested grammar points at A2.

German cases: Nominativ, Akkusativ, Dativ, Genitiv — the complete guide

Cases are the system behind German grammar. Once you understand them, articles, prepositions, and adjective endings all fall into place. This page explains each case from first principles — with examples, a practice widget, and a full pronoun reference.

TL;DR

Cases tell you the grammatical role of a noun. Ask: is this the subject (Nom), direct object (Akk), indirect object (Dat), or possessor (Gen)? The answer determines the article form. Only masculine nouns change in Akkusativ. All genders change in Dativ and Genitiv.

Why cases exist

English signals noun roles mostly through word order: "The dog bites the man" means something different from "The man bites the dog." German is more flexible with word order — because cases carry the meaning that word order carries in English.

In German, you can say Den Mann beißt der Hund (literally "The man bites the dog") and it still means the dog is doing the biting — because "den" marks "Mann" as the Akkusativ (object), and "der" marks "Hund" as the Nominativ (subject). The case endings tell you who is doing what.

This is why learning cases is not just grammar box-checking — it is the key to understanding why German word order is so flexible, and why you can front-load any part of a sentence for emphasis without losing meaning.

The 4 cases — identified by question

The fastest way to identify the case of a noun is to ask a question. The answer tells you which case to use.

Nominativ

Wer? / Was? (Who? / What?)

Subject — the noun doing the action

Der Hund bellt.

The dog is barking.

Akkusativ

Wen? / Was? (Whom? / What?)

Direct object — what the action affects

Ich sehe den Hund.

I see the dog.

Dativ

Wem? (To whom?)

Indirect object — who benefits from the action

Ich gebe dem Kind ein Buch.

I give the child a book.

Genitiv

Wessen? (Whose?)

Possession or relationship

Das Auto des Lehrers ist neu.

The teacher's car is new.

Practice: pick the right article

Each question shows a sentence with a blank. Choose the correct article for the given noun. Use number keys 1–4 to answer, Enter to advance.

Case 1: Nominativ

Nominativ is the base case — the one you see in dictionaries. Every German noun has a Nominativ form, and it is what you use when the noun is the subject of the sentence: the thing doing the action, or the thing being described after sein (to be).

The Nominativ article forms are the simplest to learn because they are the citation forms: der (masculine), die (feminine), das (neuter), die (plural).

Subject sentences:

Der Lehrer erklärt die Grammatik. — The teacher explains the grammar.
Die Katze schläft. — The cat is sleeping.
Das Buch ist interessant. — The book is interesting.

After sein, werden, and bleiben, the complement noun is also Nominativ (predicate nominative): Er ist ein Arzt.

A common mistake is treating every "der" you see as masculine. Remember: feminine Dativ and Genitiv are also "der" — context and word position disambiguate.

The indefinite article in Nominativ: ein (masculine/neuter), eine (feminine). Plural has no indefinite article — you use the bare noun or an adjective ending.

Case 2: Akkusativ

Akkusativ marks the direct object — the noun that directly receives the action of the verb. Ask: Wen? Was? (Whom? What?) to find it.

The good news: only the masculine article changes in Akkusativ. Feminine, neuter, and plural keep the same form as Nominativ. For most sentences, there is nothing to change — Akkusativ is the easiest case to get right once you spot whether the noun is masculine.

The one change to memorise:

der → den (masculine only)

Direct object sentences:

Ich sehe den Lehrer. — I see the teacher.
Er kauft die Tasche. — He buys the bag. (feminine — unchanged)
Wir essen das Brot. — We eat the bread. (neuter — unchanged)

The indefinite article change: ein (masc. Nom.) → einen (masc. Akk.). Example: Ich kaufe einen Hund.

Accusative prepositions to memorise: durch, für, gegen, ohne, um. Any noun following these words is always Akkusativ.

Case 3: Dativ

Dativ marks the indirect object — the person or thing that benefits from or is affected by the action, often corresponding to "to/for" in English. Ask: Wem? (To whom?) to find it.

Dativ has the most article changes — all four genders shift from their Nominativ forms. The trickiest part is that feminine Dativ is "der", which looks identical to masculine Nominativ. Context and noun gender are the only way to tell them apart.

Dativ definite articles:

dem (masc.) der (fem.) dem (neut.) den +n (pl.)

Indirect object sentences:

Ich gebe dem Lehrer das Buch. — I give the teacher the book.
Er hilft der Frau. — He helps the woman. ("helfen" takes Dativ)
Das Buch liegt auf dem Tisch. — The book is on the table. ("auf" + location = Dativ)

Dativ prepositions: aus, bei, mit, nach, seit, von, zu, gegenüber. These always trigger Dativ, regardless of verb.

Plural nouns in Dativ add -n to the noun if the plural does not already end in -n or -s: die Hunde → mit den Hunden.

Some verbs always take Dativ instead of Akkusativ. The most common: helfen, danken, glauben, folgen, gehören, gefallen, antworten, vertrauen. These must be learned individually.

Case 4: Genitiv

Genitiv expresses possession or a relationship between two nouns — equivalent to English "of" or the possessive apostrophe. Ask: Wessen? (Whose?) to find it.

In Genitiv, masculine and neuter nouns add -s or -es to the noun itself (in addition to the article changing). One-syllable nouns usually take -es; longer nouns take -s.

Genitiv definite articles:

des (+s/es) (masc.) der (fem.) des (+s/es) (neut.) der (pl.)

Possession sentences:

Das Auto des Lehrers ist neu. — The teacher's car is new.
Die Farbe der Wand ist weiß. — The colour of the wall is white.
Der Name des Kindes ist Lukas. — The child's name is Lukas.

Genitiv prepositions: wegen, während, trotz, statt, außerhalb, innerhalb, oberhalb, unterhalb. In spoken German these often take Dativ informally, but Genitiv is correct in writing.

In everyday speech, German increasingly uses von + Dativ instead of Genitiv: das Auto von dem Lehrer instead of das Auto des Lehrers. Both are understood; the Genitiv form is more formal.

Pronoun reference tables

Pronouns change form by case just like articles. These tables cover personal, possessive, and reflexive pronouns across all cases.

Personal Pronouns

Person	Nominativ	Akkusativ	Dativ
1st sg.	ich	mich	mir
2nd sg. (informal)	du	dich	dir
3rd sg. masc.	er	ihn	ihm
3rd sg. fem.	sie	sie	ihr
3rd sg. neut.	es	es	ihm
1st pl.	wir	uns	uns
2nd pl. (informal)	ihr	euch	euch
3rd pl. / formal	sie / Sie	sie / Sie	ihnen / Ihnen

Possessive Pronouns (Nominativ)

Possessive pronouns take the same endings as indefinite articles (ein/eine/ein). The table shows the base forms — add endings for case and gender.

Person	Base Form	+ Masc.	+ Fem.	+ Neut.	+ Plural
ich	mein	mein	meine	mein	meine
du	dein	dein	deine	dein	deine
er / es	sein	sein	seine	sein	seine
sie (sg.)	ihr	ihr	ihre	ihr	ihre
wir	unser	unser	unsere	unser	unsere
ihr	euer	euer	eure	euer	eure
sie / Sie	ihr / Ihr	ihr / Ihr	ihre / Ihre	ihr / Ihr	ihre / Ihre

Reflexive Pronouns

Person	Akkusativ	Dativ
ich	mich	mir
du	dich	dir
er / sie / es	sich	sich
wir	uns	uns
ihr	euch	euch
sie / Sie	sich	sich

Note: Only the 3rd person (er/sie/es, sie/Sie) has a unique reflexive form sich. All other persons reuse the regular accusative/dative pronouns.

How to figure out the case — a decision flowchart

When you need to choose a case, work through these questions in order:

Is there a preposition governing this noun?

If yes: use the case the preposition requires (Akk, Dat, or Gen). This overrides everything else.

Does the verb specifically require Dativ?

Verbs like helfen, danken, gefallen, gehören always take Dativ. Check your verb list.

Is this noun the subject of the sentence?

Ask: Wer / Was does the verb? → Nominativ.

Is there both a direct and indirect object?

The thing given/shown/told to someone → Dativ (Wem?). The thing itself → Akkusativ (Was?).

Does this noun show possession?

Ask: Wessen? → Genitiv. If formal writing: use des/der + noun ending. If informal: use von + Dativ.

↓

None of the above?

Default: Akkusativ. Most transitive verbs take a direct object in Akkusativ.

Case mistakes that cost time

Mistake 1

Confusing "der" Nominativ with "der" Dativ

der Hund (masculine Nominativ) and der Frau (feminine Dativ) both look the same. Context — the verb and noun gender — disambiguates.

Mistake 2

Using Akkusativ with Dativ verbs

"Ich helfe den Mann" is wrong — helfen takes Dativ. It should be dem Mann. Memorise the Dativ-verb list early.

Mistake 3

Forgetting Dativ plural -n

Plural nouns in Dativ add -n: mit den Kindern, not mit den Kinder. The extra -n is only added if the plural doesn't already end in -n or -s.

Mistake 4

Avoiding Genitiv entirely

Genitiv appears in reading, formal writing, and exams. Replacing every Genitiv with "von" in writing sounds informal. Learn to recognise and produce Genitiv at A2 level.
