German Adjective Endings – Complete Guide with Charts and Examples

Key takeaways

• German adjective endings change when an adjective appears directly before a noun — this is called attributive use.
• The ending depends on three factors: the article type (definite, indefinite, or none), the noun's grammatical case, and the noun's gender and number.
• There are three declension patterns: weak (after der/die/das), mixed (after ein/eine), and strong (no article).
• Adjectives after verbs like sein, werden, and bleiben never take endings — they stay in base form.
• Learning full noun phrases rather than isolated endings is the fastest path to fluency.

German adjective endings are one of the first grammar topics that surprises learners — the same adjective can look completely different depending on what comes before it. But the system is logical and learnable. Once you understand the three declension patterns and how article type drives ending choice, the tables start to make sense quickly.

This guide covers all three patterns in full, gives you real sentence examples for every case, explains the most common mistakes, and shows you how to build practice habits that actually stick. If you want interactive support while learning, you can explore lessons designed to help you learn to speak German at a pace that feels comfortable.

What are German adjective endings?

German adjective endings are suffixes added to adjectives when they appear directly before a noun. They reflect four things simultaneously:

• the noun's gender: masculine (der), feminine (die), or neuter (das)
• the noun's grammatical case: nominative, accusative, dative, or genitive
• the noun's number: singular or plural
• the article type preceding the adjective: definite, indefinite, or none

The article type is the most important factor — it determines which of the three declension patterns applies.

When do German adjectives take endings?

Adjectives take endings only when they stand directly before a noun (attributive position):

• ein kleines Haus — a small house
• der neue Tisch — the new table
• gute Bücher — good books (no article)

If the adjective comes after a linking verb (predicative position), it stays in its base form with no ending at all:

• Das Haus ist klein. — The house is small.
• Die Bücher sind gut. — The books are good.
• Der Tisch wird neu. — The table is becoming new.

Three types of German adjective endings

The three declension patterns — weak, mixed, and strong — exist because the adjective and article work as a team: when the article already shows gender and case clearly, the adjective carries a lighter ending. When the article is absent or ambiguous, the adjective must carry the full information.

1. Weak declension — after definite articles (der, die, das, die)

The definite article already shows gender and case fully, so the adjective only needs a minimal ending: -e in the nominative singular (and accusative for feminine/neuter), and -en everywhere else.

• Nominative: der alte Mann, die alte Frau, das alte Kind, die alten Kinder
• Accusative: den alten Mann, die alte Frau, das alte Kind, die alten Kinder
• Dative: dem alten Mann, der alten Frau, dem alten Kind, den alten Kindern
• Genitive: des alten Mannes, der alten Frau, des alten Kindes, der alten Kinder

Real sentences:

• Ich sehe den alten Mann. — I see the old man. (accusative)
• Sie hilft der alten Frau. — She helps the old woman. (dative)
• Das ist das Haus des alten Mannes. — That is the old man's house. (genitive)

2. Mixed declension — after indefinite articles (ein, eine, kein, mein…)

The indefinite article doesn't show gender in three key slots: masculine nominative (ein) and neuter nominative/accusative (ein). In those slots, the adjective must carry a strong ending to compensate. Everywhere else, the pattern follows weak declension with -en.

• Nominative: ein alter Mann, eine alte Frau, ein altes Kind
• Accusative: einen alten Mann, eine alte Frau, ein altes Kind
• Dative: einem alten Mann, einer alten Frau, einem alten Kind
• Genitive: eines alten Mannes, einer alten Frau, eines alten Kindes

Real sentences:

• Ein junger Mann steht draußen. — A young man is standing outside. (nominative, strong -er)
• Ich habe ein neues Auto. — I have a new car. (accusative neuter, strong -es)
• Sie wohnt bei einer netten Familie. — She lives with a nice family. (dative)

3. Strong declension — without any article

When no article precedes the noun, the adjective alone must show gender and case. The endings closely mirror the definite article endings:

• Nominative: kalter Kaffee, frische Luft, gutes Brot, kleine Kinder
• Accusative: kalten Kaffee, frische Luft, gutes Brot, kleine Kinder
• Dative: kaltem Kaffee, frischer Luft, gutem Brot, kleinen Kindern
• Genitive: kalten Kaffees, frischer Luft, guten Brotes, kleiner Kinder

You encounter strong declension constantly in everyday German — menus, recipes, headlines, and speech where articles are dropped for brevity:

• Frischer Fisch aus der Region. — Fresh fish from the region.
• Ich trinke gerne schwarzen Kaffee. — I like drinking black coffee.
• Mit gutem Willen ist alles möglich. — With good will, everything is possible.

German adjective endings chart — summary

A practical way to remember the system: if the article already shows a clear gender/case signal (der, dem, des, den…), the adjective takes -e or -en. If the article is missing or ambiguous (ein in masculine nominative, ein in neuter nominative/accusative), the adjective takes the full signal itself (-er, -e, -es, -em, -en).

Nominative endings by gender:

• Masculine: weak -e (der alte), mixed -er (ein alter), strong -er (alter)
• Feminine: weak -e (die alte), mixed -e (eine alte), strong -e (alte)
• Neuter: weak -e (das alte), mixed -es (ein altes), strong -es (altes)
• Plural: weak -en (die alten), mixed -en (keine alten), strong -e (alte)

Tips for learning German adjective endings

• Learn full noun phrases, not just endings. Instead of memorizing a table row by row, practice complete phrases: ein altes Haus, dem alten Mann, frischer Luft. Your brain stores them as chunks and retrieves them automatically.
• Master one declension at a time. Start with weak declension (after definite articles) — it's the most regular and covers a huge portion of everyday German. Then add mixed, then strong.
• Use color-coded charts. Highlight the three or four cells where mixed declension differs from weak (the strong-ending slots) — that's where most learner errors happen.
• Read and underline. When reading any German text, underline every adjective–noun pair and identify the declension type. This builds pattern recognition faster than drills alone.
• Speak slowly with full phrases. Saying ein kleines, rotes Auto aloud repeatedly embeds the endings through sound and rhythm, not just memory.

Why adjective endings matter

German uses endings to signal sentence structure instead of rigid word order. This means adjective endings carry real meaning — a wrong ending can change which noun is subject and which is object, or make a sentence genuinely ambiguous. When you master the patterns, you:

• understand descriptions and instructions with clarity
• express details about objects, people, and situations accurately
• read texts of any complexity more comfortably
• build grammatically correct sentences that sound natural to native speakers

German adjective endings in real sentences

Here are varied examples across all three declension types and multiple cases:

• Ich kaufe einen roten Apfel. — I'm buying a red apple. (mixed, accusative masculine)
• Wir besuchen das neue Museum. — We're visiting the new museum. (weak, accusative neuter)
• Sie spricht mit dem netten Lehrer. — She's talking with the nice teacher. (weak, dative masculine)
• Er trinkt starken Kaffee. — He drinks strong coffee. (strong, accusative masculine)
• Das ist ein schönes Bild. — That's a beautiful picture. (mixed, nominative neuter)
• Wegen schlechten Wetters bleiben wir drinnen. — Because of bad weather, we're staying inside. (strong, genitive neuter)
• Sie lebt in einer kleinen Stadt. — She lives in a small town. (mixed, dative feminine)
• Die alten Häuser stehen noch. — The old houses are still standing. (weak, nominative plural)

Final thoughts on German adjective endings

German adjective endings follow a clear system once you understand what drives them: the article tells you how much work the adjective needs to do. Master the weak pattern first, then extend to mixed and strong. With real sentences, consistent reading, and speaking practice, the endings stop feeling like rules to memorize and start feeling like a natural part of the language.
