Adjective Declension (Adjektivdeklination)

In German, adjectives change their endings depending on the case (Nominative, Accusative, Dative, Genitive), the gender (masculine, feminine, neuter, plural), and the type of article (definite, indefinite, or no article). This system is called Adjektivdeklination (Adjective Declension).

Why Is Adjective Declension Important?

Mastering Adjektivdeklination is crucial because:

• It helps in forming grammatically correct sentences.
• It ensures clarity and precision in communication.

Types of Adjective Declension

There are three main types:

Type	Example Article	Example Phrase
Strong Declension (without article)	kalt	kalter Winter
Mixed Declension (with indefinite articles: ein, kein, mein, etc.)	ein	ein kalter Winter
Weak Declension (with definite articles: der, die, das)	der	der kalte Winter

Quick Rule:

• Strong Declension → No article (adjective carries full case ending).
• Mixed Declension → Indefinite article (adjective carries some case markers).
• Weak Declension → Definite article (adjective carries weak ending: -e or -en).

Adjective Declension with Definite Articles (Weak Declension)

When the adjective follows a definite article (der, die, das, dieser, jener, jeder, alle, welcher, solcher, derselbe, etc.), it takes weak endings (-e or -en).

Declension Table – Definite Article

Case	Masculine (der)	Feminine (die)	Neuter (das)	Plural (die)
Nominative	der kalte Winter	die kalte Suppe	das kalte Wetter	die kalten Tage
Accusative	den kalten Winter	die kalte Suppe	das kalte Wetter	die kalten Tage
Dative	dem kalten Winter	der kalten Suppe	dem kalten Wetter	den kalten Tagen
Genitive	des kalten Winters	der kalten Suppe	des kalten Wetters	der kalten Tage

Key Rule:

• In Nominative & Accusative singular (except masculine Accusative) → Adjective ends in -e.
• In all other cases → Adjective ends in -en.

Examples:

Ich mag den kalten Winter.
I like the cold winter.

Sie spricht über die schöne Stadt.
She talks about the beautiful city.

Er geht mit dem netten Mann ins Kino.
He goes to the cinema with the nice man.

Die Fenster des großen Hauses sind alt.
The windows of the big house are old.

Adjective Declension with Indefinite Articles (Mixed Declension)

When using indefinite articles (ein, kein, mein, dein, sein, ihr, unser, euer, etc.), the adjective takes strong endings in some cases and weak endings in others.

Declension Table – Indefinite Article

Case	Masculine (ein)	Feminine (eine)	Neuter (ein)	Plural (-)
Nominative	ein kalter Winter	eine kalte Suppe	ein kaltes Wetter	kalte Tage
Accusative	einen kalten Winter	eine kalte Suppe	ein kaltes Wetter	kalte Tage
Dative	einem kalten Winter	einer kalten Suppe	einem kalten Wetter	kalten Tagen
Genitive	eines kalten Winters	einer kalten Suppe	eines kalten Wetters	kalter Tage

Key Rule:

• The adjective carries strong endings when the article doesn’t show case information (e.g., “ein” in nominative masculine/neuter).
• Otherwise, it follows weak endings (-en).

Examples:

Ich habe einen schönen Garten.
I have a beautiful garden.

Sie wohnt in einem kleinen Dorf.
She lives in a small village.

Er hat ein interessantes Buch gelesen.
He read an interesting book.

Ich treffe meine alten Freunde.
I meet my old friends.

Adjective Declension without Articles (Strong Declension)

When no article is present, the adjective carries all case endings (since there is no article to show the case).

Declension Table – No Article

Case	Masculine	Feminine	Neuter	Plural
Nominative	kalter Winter	kalte Suppe	kaltes Wetter	kalte Tage
Accusative	kalten Winter	kalte Suppe	kaltes Wetter	kalte Tage
Dative	kaltem Winter	kalter Suppe	kaltem Wetter	kalten Tagen
Genitive	kalten Winters	kalter Suppe	kalten Wetters	kalter Tage

Key Rule:

• These endings match definite article endings (der, die, das), making it easier to remember!

Examples:

1. 1. 1. Alter Wein schmeckt oft besser. (Old wine often tastes better.)
      2. Ich liebe gute Musik. (I love good music.)
      3. Er fährt mit neuem Auto. (He drives with a new car.)

Special Cases: viele, manche, mehrere, einige, numbers

Words like viele, manche, einige, mehrere (many, some, several) behave like no article → Strong declension.

Singular (Strong)	Plural (Strong)
viel guter Wein (much good wine)	viele gute Bücher (many good books)
manch schönes Haus (some beautiful house)	manche alten Häuser (some old houses)
einige nette Person (some nice person)	einige nette Leute (some nice people)
mehrere große Gebäude (several big buildings)

Numbers (zwei, drei, vier, etc.) also behave like no article → Strong declension.

• drei interessante Filme (three interesting films)
• zwei große Städte (two big cities)
