Adjective endings in German can be challenging because they depend on the noun’s case (nominative, accusative, dative, genitive), gender (masculine, feminine, neuter), and number (singular or plural). Mastering these endings helps you sound more natural and precise in German. This guide explains what you need to know about German adjective declension and shows you how to learn these endings step by step.
What Is the German Adjective Declension?
German adjective declension is the system of changing adjective endings based on the noun’s article (definite, indefinite, possessive, or no article) and the case and gender of that noun. These endings signal important grammatical details. If you use the wrong ending, native speakers may still understand you, but it can sound off or confusing.
An adjective in German agrees with its noun in both gender (masculine, feminine, neuter) and case (nominative, accusative, dative, genitive). This is why learners should already know German articles and German cases for a smoother experience.

When there is no article at all, you normally use "strong" endings, because these endings carry the grammatical information that would otherwise come from an article.
Example Sentences (Zero Articles)
Guter Wein schmeckt lecker. (Nominative) = Good wine tastes delicious.
Ich trinke guten Wein. (Accusative) = I drink good wine.
Ich spreche mit gutem Freund. (Dative) = I speak with a good friend.
Adjective endings can be tricky, and many learners make the same mistakes. Below are the most frequent errors and how to correct them.
❌ Mistake 1: Wrong Endings After Definite Articles
When using der, die, das, the adjective takes a weak ending (-e or -en).
🔴 Incorrect: Der großer Mann ist nett. ✅ Correct: Der große Mann ist nett.
❌ Mistake 2: Forgetting Strong Endings with No Article
If there is no article, the adjective must show case, gender, and number.
🔴 Incorrect:Ich trinke gut Wein. ✅ Correct:Ich trinke guten Wein.
❌ Mistake 3: Mixing Up Accusative and Dative Forms
Some learners use accusative endings instead of dative endings or vice versa.
🔴 Incorrect: Ich sehe schönem Sand. ✅ Correct: Ich sehe schönen Sand.
❌ Mistake 4: Using Weak Endings After Indefinite Articles
After ein, eine, kein, the adjective takes mixed endings, not weak ones.
🔴 Incorrect:Ein kluge Mann liest ein Buch. ✅ Correct:Ein kluger Mann liest ein Buch.
❌ Mistake 5: Forgetting Plural Endings
Adjectives in the plural must agree with case and article presence.
🔴 Incorrect:Ich sehe die kleine Hunde. ✅ Correct:Ich sehe die kleinen Hunde.
❌ Mistake 6: Ignoring Gender Rules
Some learners guess adjective endings instead of following gender rules.
🔴 Incorrect: Ich mag die schönes Auto. ✅ Correct: Ich mag das schöne Auto.
