Accusative case for direct objects (den, einen and accusative pronouns)

This guide explains the German accusative case used for direct objects. You will learn what the accusative means, when to use it, how to form the accusative for articles (especially den and einen), and how accusative pronouns work. Many clear German examples are given with English translations.

What is the accusative case?

What does “accusative” mean?

Short definition
- The accusative case (Akkusativ) marks the direct object of a verb — the person or thing that is directly affected by the action.
- In German you change articles and pronouns to show the accusative.
- To find the direct object in German ask: Wen? (Whom?) or Was? (What?).

Examples
- Ich sehe den Mann. — I see the man. (Wen sehe ich? den Mann.)
- Er isst den Apfel. — He is eating the apple. (Was isst er? den Apfel.)
- Ich kenne dich. — I know you. (Dich is the accusative pronoun for you.)

English connection
- English changes pronouns (he → him), but not articles. German changes both pronouns and articles: der Mann (subject) → den Mann (direct object).

When do I use the accusative?

Direct objects (Wen? Was?) — the most common use

Use the accusative when a verb acts directly on a person or a thing.
Common verbs that take an accusative object: sehen (to see), haben (to have), lesen (to read), kaufen (to buy), essen (to eat), trinken (to drink), lieben (to love), besuchen (to visit), suchen (to look for), hören (to hear).

Examples:
- Ich sehe den Hund. — I see the dog.
- Sie hat einen Bruder. — She has a brother.
- Wir lesen das Buch. — We read the book.
- Er besucht seine Großmutter. — He visits his grandmother.

Accusative with certain prepositions (brief note)

Some prepositions always take the accusative: durch, für, gegen, ohne, um, bis.
Example: Das Geschenk ist für den Lehrer. — The gift is for the teacher. (für always + accusative)
Note: This is different from direct objects, but you will see the accusative form here too.

Don’t confuse accusative with dative

Dative marks the indirect object (to whom/for whom). Many learners mix them up because English uses word order instead of case endings.
Example to compare:
Ich gebe dem Mann den Ball. — I give the man the ball. (dem Mann = dative; den Ball = accusative)
Wem gebe ich den Ball? → dem Mann (dative)
Wen/was gebe ich? → den Ball (accusative)
Some verbs in German take dative rather than accusative (e.g., helfen, danken). English speakers often make errors here. Example: Ich danke dir. — I thank you. (dative dir, not accusative dich)

How do I form the accusative?

Definite articles: der → den (masculine); others stay the same

Nominative → Accusative (definite articles):
Masculine: der → den
Feminine: die → die
Neuter: das → das
Plural: die → die

Examples:
- Der Mann sieht den Hund. — The man sees the dog. (den Hund = direct object)
- Ich kenne die Frau. — I know the woman. (die Frau stays die)
- Er hat das Buch. — He has the book.
- Wir kaufen die Bücher. — We buy the books.

Indefinite articles: ein → einen (masculine)

Indefinite articles follow the same pattern for gender in accusative:
Masculine: ein → einen
Feminine: eine → eine
Neuter: ein → ein
(There is no indefinite plural; use keine / some or no article.)

Examples:
- Ich sehe einen Mann. — I see a man.
- Sie hat eine Schwester. — She has a sister.
- Er kauft ein Auto. — He buys a car.

Negation with kein: kein → keinen (masculine)

kein behaves like ein: Masculine accusative becomes keinen.
Example: Ich habe keinen Hund. — I don’t have a dog.

Possessive determiners and adjective endings (brief note)

Possessives (mein, dein, sein, ihr, unser, euer, Ihr) follow the article pattern. Masculine accusative receives an -en ending: meinen, deinen, seinen, ihren, unseren, euren, Ihren.
Adjectives after an article in masculine accusative usually end in -en: den großen Hund, einen großen Hund.

Examples:
- Ich besuche meinen Bruder. — I visit my brother. (mein → meinen)
- Sie fährt den alten Wagen. — She drives the old car. (den alten Wagen)
- Ich habe einen roten Apfel. — I have a red apple. (einen + roten)

Accusative pronouns

Personal pronouns (nominative → accusative)

ich → mich (me)
du → dich (you, singular informal)
er → ihn (him/it for masculine nouns)
sie → sie (her or them; lowercase sie can be her or them)
es → es (it)
wir → uns (us)
ihr → euch (you, plural informal)
sie → sie (they → them)
Sie → Sie (formal you, remains Sie in accusative; capitalized in writing)

Examples replacing nouns with pronouns:
- Ich sehe den Mann. → Ich sehe ihn. — I see him.
- Ich frage die Frau. → Ich frage sie. — I ask her.
- Er nimmt das Buch. → Er nimmt es. — He takes it.
- Kommst du mit? Sie sucht uns. — Are you coming? She is looking for us.
- Ich sehe Sie. — I see you (formal).

Reflexive verbs — accusative reflexive pronouns

Many reflexive verbs use accusative reflexive pronouns: mich, dich, sich, uns, euch, sich.
Examples:
Ich wasche mich. — I wash myself.
Du rasierst dich. — You shave yourself.
Er freut sich. — He is happy (literally: he rejoices himself).

Notes on ambiguity: sie, Sie

sie (lowercase) can mean her (singular feminine accusative) or them (plural accusative). Context tells you which.
Sie (capitalized) is the polite/formal you in both nominative and accusative. Writing capitalization helps avoid confusion.

How to find the direct object (quick method)

Step-by-step

Step 1: Find the verb.
Step 2: Ask Wen? (Whom?) for people or Was? (What?) for things.
The answer is the accusative object.

Examples:
- Der Hund beißt den Mann. — Wen beißt der Hund? den Mann. (accusative)
- Ich gebe dem Kind einen Ball. — Wem gebe ich den Ball? dem Kind (dative). Wen gebe ich? → den Ball (accusative).
- Maria liest das Buch. — Was liest Maria? das Buch (accusative).

Tips:
- If the verb expresses giving, showing, telling, etc., you will often have both a dative (receiver) and an accusative (thing given).
- Learn common verbs that require dative (helfen, danken, folgen, gefallen, gehören) to avoid mistaken accusative use.

Common mistakes and how to avoid them

Typical errors

Using nominative instead of accusative for the direct object:
Wrong: Ich sehe der Mann. — Correct: Ich sehe den Mann.
Forgetting to change ein → einen for masculine accusative:
Wrong: Ich habe ein Hund. — Correct: Ich habe einen Hund.
Mixing up accusative and dative pronouns (ihn vs. ihm):
Wrong: Ich gebe ihn das Buch. — Correct: Ich gebe ihm das Buch. (giving requires dative for the person)
Using the wrong pronoun case:
Wrong: Er sieht ich. — Correct: Er sieht mich.
Confusing sie (her/them) and Sie (formal you): remember capitalization and context.

How to avoid these mistakes

Always ask Wen? or Was? to find the accusative.
Learn the gender of nouns (der/die/das). Masculine nouns are the only ones that change definite article in accusative (der → den).
Remember that some verbs require dative, not accusative.
When replacing a noun with a pronoun, double-check the pronoun’s form (mich/dich/ihn/uns/euch/sie/ihnen etc.).

Summary

- The accusative marks the direct object — ask Wen? or Was? to find it.
- Only masculine singular definite and indefinite articles change in the accusative (der → den; ein → einen). Negation kein behaves the same way (kein → keinen).
- Pronouns change in the accusative (ich → mich, du → dich, er → ihn, etc.). Reflexive verbs often use accusative reflexive pronouns (mich, dich, sich, uns, euch, sich).
- Watch out for verbs that require dative instead of accusative and for prepositions that always take the accusative.
