The Accusative Case | German Grammar

The accusative is the case German uses for the direct object — the thing that is directly affected by the verb's action. If the subject (nominative) is the doer, the direct object (accusative) is the done-to. When you see a man, buy an apple, or read a book, those things are accusative. The good news is that the accusative is the gentlest of the four cases to learn, because for three of the four gender/number columns it looks identical to the nominative. The catch — and it is a big one — is that the single column that does change, the masculine, is also one of the most common nouns you'll ever use, and forgetting to change it is the most frequent case error English speakers make.

What the accusative does

Ask "wen oder was?" ("whom or what?") after the verb. The answer is your direct object, and it takes the accusative.

Ich sehe den Mann.

I see the man. (Whom do I see? → den Mann)

Sie kauft einen Apfel.

She is buying an apple. (What is she buying? → einen Apfel)

Wir lesen das Buch zusammen.

We're reading the book together. (What are we reading? → das Buch)

In each case the verb does something to a separate thing, and that thing is the accusative object. This is genuinely different from the nominative-after-sein situation: sehen, kaufen, lesen act on real objects, whereas sein merely equates.

Only masculine changes — and that's the whole story

Here is the accusative laid next to the nominative so you can see exactly what moves:

	Masculine	Feminine	Neuter	Plural
Nominative	der / ein	die / eine	das / ein	die
Accusative	den / einen	die / eine	das / ein	die

Look at the rows: feminine die/eine, neuter das/ein, and plural die are unchanged. The only cell that moves is the masculine: der → den and ein → einen. That is the entire visible accusative for articles. Everything else is the same word it was in the nominative.

Ich brauche eine Pause und ein Glas Wasser.

I need a break and a glass of water. (feminine + neuter — both unchanged)

Sie liest die Zeitung und das Buch.

She's reading the newspaper and the book. (feminine + neuter object, unchanged)

Why masculine 'den' is the system's biggest trap

You might think a case that only changes one form would be easy. The opposite is true, and the reason is psychological. Because feminine, neuter, and plural objects don't change, learners quietly conclude that "the accusative usually does nothing" — and then they forget to change the one form that matters. Masculine nouns are extremely common (der Mann, der Hund, der Tisch, der Wagen, der Brief), so this single missed change shows up constantly.

The cleanest way to feel the rule is a minimal pair where only the roles swap:

Der Hund sieht den Mann.

The dog sees the man. (dog = subject → der; man = object → den)

Der Mann sieht den Hund.

The man sees the dog. (man = subject → der; dog = object → den)

The article tells you who is doing the seeing and who is being seen. In German, word order is flexible precisely because the case carries this information — so getting der vs. den right is not decoration, it's how the listener knows who did what. You could even front the object:

Den Hund sieht der Mann (nicht umgekehrt).

It's the dog the man sees (not the other way around).

Even though den Hund comes first, the accusative article marks it as the object, and der Mann stays the subject. English, which fixed its word order centuries ago, leans entirely on position; German leans on case.

💡

If a masculine noun is a direct object and you wrote der or ein, stop and fix it to den or einen. This one habit eliminates the most common beginner error in the language.

Accusative personal pronouns

Pronouns change far more visibly than articles do, so they're a great place to internalize the case. These are the forms you use when a pronoun is the direct object:

Person	Nominative	Accusative
I / me	ich	mich
you (informal sg.)	du	dich
he / him	er	ihn
she / her	sie	sie
it	es	es
we / us	wir	uns
you (informal pl.)	ihr	euch
they / them; you (formal)	sie / Sie	sie / Sie

Ich liebe dich.

I love you.

Kennst du ihn?

Do you know him?

Ruf mich bitte heute Abend an.

Please call me tonight.

Notice er → ihn — the masculine pronoun changes just like the masculine article, which is a nice consistency: masculine is where the accusative always shows itself, whether on an article or a pronoun.

Common mistakes

❌ Ich sehe der Mann.

Incorrect — a masculine direct object must be accusative 'den'. This is the single most common case error in German.

✅ Ich sehe den Mann.

I see the man.

❌ Sie kauft ein Apfel.

Incorrect — 'Apfel' is masculine, so as a direct object the article becomes 'einen'.

✅ Sie kauft einen Apfel.

She's buying an apple.

❌ Ich kenne er gut.

Incorrect — a pronoun object takes the accusative: 'er' becomes 'ihn'.

✅ Ich kenne ihn gut.

I know him well.

❌ Ich frage der Student.

Incorrect — 'Student' is a masculine n-declension noun, so the object is 'den Studenten' (article changes AND noun adds -en).

✅ Ich frage den Studenten.

I'm asking the student.

❌ Hast du das Brief gelesen?

Incorrect — 'Brief' is masculine (der Brief), so the object is 'den Brief', not neuter 'das'.

✅ Hast du den Brief gelesen?

Did you read the letter?

Key takeaways

The accusative marks the direct object — answer "wen oder was?" after the verb.
Of the four article columns, only masculine changes: der → den, ein → einen. Feminine, neuter, and plural look exactly like the nominative.
That single change is the most frequent stumbling block in German, because masculine nouns are so common and learners assume "the accusative does nothing."
Masculine n-declension nouns add -(e)n as well: den Studenten, den Herrn, den Jungen.
Pronouns change visibly (mich, dich, ihn, uns, euch); see the full system in accusative and dative pronouns. Next, learn the prepositions that always take the accusative and the accusative of time and measure.
