What are the four German cases?

German has nominative (subject), accusative (direct object), dative (indirect object), and genitive (possession). Articles and adjective endings change depending on the case.

How do I know if it is accusative or dative?

Check the verb and the preposition. Many verbs take an accusative object, some take dative, and many prepositions always require one case. Two-way prepositions use accusative for motion and dative for location.

Is genitive still used in German?

Yes, especially in formal writing and set expressions. In everyday speech, Germans often use dative constructions instead, but genitive is still important to recognize and use.

What is the fastest way to practice cases?

Practice with short sentences that force you to pick the right article and pronoun (der/den/dem/des; ich/mich/mir; etc.), and mix in the most common prepositions.

German Cases: The Complete Guide

German has four grammatical cases that change how articles, adjectives, and pronouns are declined. Understanding cases is essential for speaking German correctly.

Cases feel hard when you try to memorize tables first. They get much easier when you learn what each case does in a sentence, and you follow a simple decision process.

Fastest shortcut

If you only memorize one thing, memorize the pronouns: ich/mich/mir, du/dich/dir, er/ihn/ihm, wir/uns/uns. Pronouns make the case obvious even when noun endings feel confusing. (See also: German pronouns.)

A Practical Checklist (How to Pick the Case)

Use this in real sentences. It’s the same thought process German speakers learn in school:

Is there a preposition? Learn the preposition with its case (mit + dative, fuer + accusative, wegen + genitive, etc.). (See also: German prepositions.)
Is it a two-way preposition (in/an/auf/unter/ueber/vor/hinter/neben/zwischen)?
- Motion/destination (wohin?) → usually accusative
- Location/state (wo?) → usually dative
What is the subject (who/what does the action)? That noun phrase is nominative.
What is the direct object (what gets acted on)? That noun phrase is usually accusative.
Is there an indirect recipient (to/for whom)? That noun phrase is usually dative.
Is it possession (“of”, “whose”)? That noun phrase can be genitive (especially in writing) or replaced with a dative/von construction in speech.

Overview: The Four Cases

Case	Masculine	Feminine	Neuter	Plural
Nominativ	der / ein	die / eine	das / ein	die / -
Akkusativ	den / einen	die / eine	das / ein	die / -
Dativ	dem / einem	der / einer	dem / einem	den / -
Genitiv	des / eines	der / einer	des / eines	der / -

Nominativ (Nominative Case)

The nominative case marks the subject of a sentence - the person or thing performing the action.

Nominativ

Der Mann liest ein Buch.

The man reads a book.

When to Use Nominativ

Subject of any sentence: Who or what is doing the action
After "sein" (to be), "werden" (to become), and "bleiben" (to stay/remain) (these don’t take a direct object)

Nominativ

Das ist ein guter Freund.

That is a good friend.

Nominativ

Er bleibt ein Student.

He remains a student.

Remember

The nominative is the "dictionary form" - it's what you'll find when looking up a noun.

Akkusativ (Accusative Case)

The accusative marks the direct object - what is directly affected by the action.

Akkusativ

Ich sehe den Mann.

I see the man.

When to Use Akkusativ

Direct objects: What receives the action directly
After accusative prepositions: durch, für, gegen, ohne, um, bis, entlang
With two-way prepositions indicating motion toward a destination

Akkusativ

Sie geht durch den Park.

She walks through the park.

Useful Extra: Time & Distance (Often Akkusativ)

German often uses the accusative for “how long / how far”:

Akkusativ

Ich lerne jeden Tag Deutsch.

I study German every day.

Akkusativ

Wir warten eine Stunde.

We wait for an hour.

Akkusativ Article Changes

Case	Masculine	Feminine	Neuter	Plural
Nominativ	der / ein	die / eine	das / ein	die / -
Akkusativ	den / einen	die / eine	das / ein	die / -
Dativ	dem / einem	der / einer	dem / einem	den / -
Genitiv	des / eines	der / einer	des / eines	der / -

Only masculine articles change in the accusative: der → den, ein → einen. Feminine, neuter, and plural stay the same!

Dativ (Dative Case)

The dative marks the indirect object - who receives the direct object or benefits from the action.

Dativ

Ich gebe dem Mann das Buch.

I give the book to the man.

When to Use Dativ

Indirect objects: To whom something is given/said/shown
After dative prepositions: aus, außer, bei, gegenüber, mit, nach, seit, von, zu
After certain verbs: helfen, danken, gefallen, gehören, folgen, antworten
With two-way prepositions indicating location (no motion)

Dativ

Das Buch gehört meiner Schwester.

The book belongs to my sister.

Most common dative patterns

Two situations create tons of dative in everyday German:

mit + dative: mit dem Freund, mit der Frau, mit den Kindern
verbs like helfen and gefallen: Das hilft mir. Das gefaellt mir.

Dativ Article Changes

Dative articles - note the -m endings for masculine/neuter
	Masculine	Feminine	Neuter	Plural
Definite	dem	der	dem	den (+n)
Indefinite	einem	einer	einem	—

Don't Forget!

In the dative plural, nouns add -n if they don't already end in -n or -s: "den Kindern", "den Häusern"

Two-Way Prepositions (Accusative vs Dative)

Two-way prepositions (Wechselpraepositionen) can be accusative or dative depending on meaning:

wohin? (to where / destination / change of position) → usually accusative
wo? (where / location / no movement) → usually dative

Common two-way prepositions: in, an, auf, unter, ueber, vor, hinter, neben, zwischen

Akkusativ

Ich gehe in die Schule.

I’m going to school. (destination)

Dativ

Ich bin in der Schule.

I’m at school. (location)

Akkusativ

Ich haenge das Bild an die Wand.

I hang the picture onto the wall. (movement)

Dativ

Das Bild haengt an der Wand.

The picture is hanging on the wall. (location)

Quick test

If you can answer with “here/there” (location), think dative. If you can answer with “to there” (destination), think accusative.

Genitiv (Genitive Case)

The genitive shows possession - whose something is.

Genitiv

Das ist das Auto des Mannes.

That is the man's car.

When to Use Genitiv

Possession: Whose something belongs to
After genitive prepositions: wegen, trotz, während, statt, innerhalb, außerhalb

Genitiv

Trotz des Regens gehen wir spazieren.

Despite the rain, we go for a walk.

Genitiv Article Changes

Genitive articles - masculine/neuter nouns also add -s or -es
	Masculine	Feminine	Neuter	Plural
Definite	des (+s/es)	der	des (+s/es)	der
Indefinite	eines (+s/es)	einer	eines (+s/es)	—

Masculine and neuter nouns in the genitive usually add -s (des Autos) or -es for words ending in s, ß, x, z (des Hauses).

Real-life note

In everyday speech, Germans often replace genitive with a simpler structure: von + dative (Das Auto von dem Mann) or possessive forms. But genitive is still very common in writing and set phrases, so you should recognize it quickly.

Genitiv	des / eines	der / einer	des / eines	der / -

Quick Tips for Remembering Cases

The Accusative Rule

If you can replace the noun with "him/her/it" in English, it's probably accusative. "I see him" → Ich sehe ihn.

The Dative Rule

If you can add "to" or "for" before the noun in English, it's probably dative. "I give (to) him the book" → Ich gebe ihm das Buch.

The Genitive Rule

If you can use "'s" or "of" in English, it's genitive. "The man's car" / "The car of the man" → Das Auto des Mannes.

Common Case Mistakes (and How to Fix Them)

Mistake 1: Using nominative after a preposition

Prepositions don’t care what “feels like a subject”. They require a case. For example, it’s mit dem Mann (dative), not “mit der Mann”.

Mistake 2: Forgetting the dative plural

In dative plural you often need two changes: den + noun + -n (if possible). Example: mit den Kindern.

Mistake 3: Two-way prepositions without thinking motion vs location

Don’t memorize “in = dative” or “in = accusative”. Memorize the meaning: in + destination (acc) vs in + location (dat).
