Adjective Declension

Let's build flexible sentences, by learning how to properly decline adjectives in the nominative and accusative cases.

Attributive Adjectives

In the previous lesson, we used predicative adjectives, where the adjective comes after the verb. For example:

Die Schildkröte ist grün und isst einen Apfel.

The turtle is green and eats an apple.

Predicative adjectives rely on a linking verb, like ist in the sentence above.

However, attributive adjectives come before the noun and don’t need a linking verb, allowing for more flexibility in sentence structure. For example:

Die grüne Schildkröte isst einen Apfel.

The green turtle eats an apple.

Notice how the adjective grün is declined to grüne. This is because, when placed before the noun, both the article & the adjective become responsible for indicating it‘s case.

... are used after the noun... are used just before the noun
... don't decline... decline

Declension Indicates Case

In German, identifying the case of a noun is important because it tells us the role it plays in a sentence, such as a subject or object. We can determine the noun’s case through declension.

Declension is the process of changing (inflecting) adjectives, nouns, articles, and pronouns to reflect the German cases.

Two types of words undergo declension: determiners (like articles) and attributive adjectives.

TypeExampleDeclines?
definite articlesder, die, das👍
indefinite articlesein, eine👍
adjectiveslecker, groß, schön👍

Check out these sentences:

Der durstige Mann trinkt Wasser

the thirsty man drinks water
Durstiger Männer trinken Wasser

thirsty men drink water

In both, the case of the noun der Mann is clear through the declension of the article and/or adjective (nominative).

Adjective Declension (Nominative & Accusative)

Strong, Weak and Mixed Declension

Now that we know that attributive adjectives must decline, let's learn how to do this.

There are three ways to decline adjectives: strong, mixed and weak.

Strong Declension:

Accden roten Apfeldie rote Blumedas rote Hausdie roten Autos
Datdem roten Apfelder roten Blumedem roten Hausden roten Autos
Gendes roten Apfelsder rote Blumedes rote Hausesder roten Autos
Weak Declension

Notice that weak declension only uses -e and -en endings, while strong declension uses -er, -e, and -es endings to indicate noun gender as well as case, just like definite articles do.

To determine which type of declension to use, we can follow these rules:

  • no article + adjective + noun → strong declension
  • indefinite article ('ein', 'mein') + adjective + noun → mixed declension
  • definite article + adjective + noun → weak declension

Exercise

Now, take a look at the sentences below and try to correctly decline the adjectives, using the rules above.

1.
DasverwirrtMädchenwirftdenstinkendFischweg.
2.
EinschnellGepardfängteinlangsamSchwein.
3.
DerbösManntöteteineunschuldigFrau.
4.
DerfreundlichLehrerbegrüßtdennervösSchüler.
5.
DergroßeElefantfrisstkleinErdnüsse.

Summary

Key things to consider when declining adjectives:

  • Noun gender (die Schildkröte, der Apfel)
  • Noun case (nominative or accusative)
  • Whether to use strong, mixed or weak declension
