German Declension

Let's learn how to build sentences with a subject and an object.

In the last lesson, we learned how to conjugate verbs, helping us to build simple sentences with a subject and an action.

Die Oma
+
trinkt.

Grandma drinks.

Now, let's take our sentence-building skills further by adding something new: an object.

Die Oma
+
trinkt
+
den Wein.

Grandma drinks the wine.

Nominative & Accusative

You may have noticed an unfamiliar article in the sentence above: den. This is simply the article der, but declined. To use objects correctly, we need to learn about the German cases and declension.

In the German language, there are four cases:

  1. Nominative
  2. Accusative
  3. Dative
  4. Genitive
Cases tell us what role a noun plays in a sentence:

CaseRolePurpose
nominativesubjectperforms action
accusativedirect objectreceives action
dativeindirect objectto/for whom action is taken
genetivepossessiveindicates possession of someone / something

For now, we'll focus on two cases: the nominative and accusative cases, which we can use to create sentences with a subject and a direct object. Take a look at this sentence:

Der Mann
+
wirft
+
den Ball.

The man throws the ball

What is the subject (the action performer)? It’s der Mann.
What is the object (the action receiver)? It’s den Ball.

How do we know which case is being used? In this example, German declension shows us. Den Ball is the declined form of der Ball, and the article den is in the accusative case, telling us that den Ball is the direct object.

CaseRoleArticleNoun
nominativesubjectderBall
accusativedirect objectdenBall

On the other hand, der Mann is not declined, and the article der is in the nominative case, telling us that der Mann is the subject.

CaseRoleArticleNoun
nominativesubjectderMann
accusativedirect objectdenMann
In English, “The man throws the ball” and “The ball throws the man” have different meanings because word order matters. In German, though, 'Der Mann wirft den Ball' and 'Den Ball wirft der Mann' mean the same thing. This is because, in this example, declension indicates each noun's role.

Now that we've learned about the nominative and accusative cases, let’s dive into article declension.

Definite Articles & Plural Declension

Take a look at this grammar table to see how definite and plural articles change in the nominative and accusative cases:

CaseMasculineFeminineNeuterPlural
nominativederdiedasdie
accusativedendiedasdie

Most articles stay the same in both cases. The only exception is the masculine article der, which changes to den in the accusative case. Using this table, pick the correct articles for each sentence:

1.Das Kind fängt Schmetterling.
2. Opa grüßt den Onkel.
3.Das Mädchen isst Abendessen.

Indefinite Article Declension

Now, let’s look at indefinite article declension for the accusative and nominative cases:

MasculineFeminineNeuter
nominativeeineineein
accusativeeineneineein

Definite articles describe specific nouns:

Das Kind lacht.

The child laughs.

Indefinite articles describe non-specific nouns:

Ein Kind lacht.

A child laughs.

As with definite articles, most indefinite articles stay the same, except for the masculine ein, which changes to einen in the accusative case. Using the table, choose the correct article for each sentence:

1.Die Männer fangen Löwen.
2. Löwe jagt einen Büffel.
3.Amina kauft Teppich.

Well done! 🎉

You may have noticed that the first sentence uses einen Löwen and the second uses ein Löwe. The extra -n is added because the noun is declined. Let's take a closer look at noun declension, in the next part of this lesson.

N-Declension

In German, certain masculine nouns decline in the accusative case as well as in the plural form, along with their articles. This is done by adding -(e)n to the noun.

CaseDefiniteIndefiniteNoun
nominativedereinLöwe
accusativedeneinenLöwen

As a general rule, the masculine nouns that decline this way usually end with -e, -ant, -at, -ist, or -ent. Here’s a grammar table showing N-declension rules for the nominative and accusative cases:

CaseSingularPlural
nominativeder Löwedie Löwen
accusativeden Löwendie Löwen

For these nouns, you must add -(e)n in every case except the nominative singular. Using this table, pick the correct forms for each sentence:

1.Der Kollege ruft an.
2.Der Tiger jagt .
3. ruft der Mann.
Over time, you'll learn which masculine nouns require N-declension. What’s important now is understanding when and how to decline them.

Well done 🎉!

You’ve now learned how to decline definite and indefinite articles, and nouns with N-declension, in both the nominative and accusative cases! Your sentences now include a subject, action, and object.

In the next lesson, we’ll dive into German pronouns. Head over when you're ready!
