Learn this properly in the German B1 course
Handle opinions, arguments and everyday problems the way Germans actually phrase them.
See the B1 courseGerman adjective endings are one of the most feared topics for learners at the A2 and B1 level. You have already learned the German cases and how der, die, das work, and now adjectives seem to throw a wrench into everything. But here is the good news: the system behind German adjective endings is actually logical, and once you understand the core principle, the charts almost memorize themselves.
This guide gives you all three adjective ending patterns with clear charts, the one trick that ties them together, and practical exercises to lock everything in.
In English, adjectives never change form. "The big dog," "a big dog," "big dogs" — the word "big" stays the same every time. German works differently because it is an inflected language. The ending on an adjective carries grammatical information about the noun it describes: its gender (masculine, feminine, neuter), its number (singular or plural), and its case (nominative, accusative, dative, genitive).
This means the adjective ending is not random. It is doing a job. Specifically, someone in the noun phrase has to signal the gender and case of the noun. If the article already does that job clearly (like der, die, das, dem, den), the adjective can relax and take a weak, simple ending. If there is no article, or if the article does not show the gender and case clearly enough (like ein in nominative masculine and nominative/accusative neuter), the adjective has to step up and carry that signal itself.
This single idea — someone must signal the case and gender — is the master key to the entire system.
Learners struggle with adjective endings for several overlapping reasons:
The antidote is understanding the underlying logic rather than brute-force memorization. Once you see the pattern, the charts shrink dramatically.
The trick is the strong/weak principle:
If the article already shows a strong, clear signal for gender and case, the adjective takes a weak ending (-e or -en). If the article does NOT show a clear signal — or there is no article at all — the adjective takes a strong ending that mirrors what the definite article would have been.
Here is what that means in practice:
This principle covers roughly 90% of cases. The remaining 10% are the -en endings that appear across all dative and genitive slots and all plurals with articles.
Let us now look at the three complete charts.
There are three adjective ending patterns in German, traditionally called:
When a definite article (or dieser, jeder, welcher, alle) precedes the adjective, the article is already doing the heavy lifting. The adjective just adds -e or -en.
| Case | Masculine | Feminine | Neuter | Plural |
|---|---|---|---|---|
| Nominative | der alte Mann | die alte Frau | das alte Haus | die alten Häuser |
| Accusative | den alten Mann | die alte Frau | das alte Haus | die alten Häuser |
| Dative | dem alten Mann | der alten Frau | dem alten Haus | den alten Häusern |
| Genitive | des alten Mannes | der alten Frau | des alten Hauses | der alten Häuser |
Memory shortcut: Nominative (all genders) and accusative (feminine + neuter) get -e. Everything else gets -en. That is only 5 cells with -e and 11 with -en.
After ein, kein, or possessive pronouns (mein, dein, sein, ihr, unser, euer), most endings look the same as Pattern 1. The difference appears in exactly three cells where ein does not clearly signal gender:
| Case | Masculine | Feminine | Neuter | Plural (kein/mein...) |
|---|---|---|---|---|
| Nominative | ein alter Mann | eine alte Frau | ein altes Haus | keine alten Häuser |
| Accusative | einen alten Mann | eine alte Frau | ein altes Haus | keine alten Häuser |
| Dative | einem alten Mann | einer alten Frau | einem alten Haus | keinen alten Häusern |
| Genitive | eines alten Mannes | einer alten Frau | eines alten Hauses | keiner alten Häuser |
Key difference from Pattern 1: Look at the three bold cells — nominative masculine (-er), nominative neuter (-es), and accusative neuter (-es). These are exactly the spots where ein alone does not tell you the gender. The adjective compensates by taking the strong ending.
When no article is present, the adjective itself must carry the full gender/case signal. The endings mirror the definite article endings almost exactly:
| Case | Masculine | Feminine | Neuter | Plural |
|---|---|---|---|---|
| Nominative | alter Wein | kalte Milch | frisches Brot | neue Bücher |
| Accusative | alten Wein | kalte Milch | frisches Brot | neue Bücher |
| Dative | altem Wein | kalter Milch | frischem Brot | neuen Büchern |
| Genitive | alten Weines | kalter Milch | frischen Brotes | neuer Bücher |
Memory shortcut: Compare these endings to the definite articles: der → -er, die → -e, das → -es, dem → -em, den → -en. The adjective is basically pretending to be the article. The only exceptions are genitive masculine and genitive neuter, where the adjective takes -en instead of -es (because the noun itself already ends in -s or -es).
Here is one unified way to think about all three patterns:
| Situation | What the adjective does |
|---|---|
| Article shows clear signal | Weak ending: -e or -en |
| Article shows unclear signal | Strong ending in that slot only |
| No article at all | Strong endings everywhere |
The strong endings are simply the endings of der/die/das/dem/den, with genitive masculine and neuter as the sole exception (-en instead of -es).
Ich trinke kalt Wasser. → Ich trinke kaltes Wasser.
Every attributive adjective (one that comes before a noun) must have an ending. Predicate adjectives (after sein, werden, bleiben) do not: Das Wasser ist kalt — no ending needed.
Ein alte Mann sitzt dort. → Ein alter Mann sitzt dort.
This is the most common error. Remember: after ein in nominative masculine, the adjective needs the strong ending -er because ein alone does not signal masculine.
Whenever an article is present and you are in the dative case, the adjective ending is -en. No exceptions. Mit dem/einem/meinem alten Freund.
Der Hund ist großer. → Der Hund ist groß.
Adjectives only get endings when they come before the noun. After sein/werden/bleiben, they stay in their base form.

Reading charts is one thing. Building fluency is another. Here are the best ways to make adjective endings automatic:
Speed-based games force you to process German word forms quickly without overthinking. Try Word Scramble to unscramble adjective-noun combinations. The faster you recognize correct forms, the more natural they become.
Structured quizzes give you targeted practice with instant feedback. Our grammar quizzes include exercises specifically on adjective endings, cases, and article usage — all the building blocks you need.
When you read German, pause at every adjective and identify: What is the article? What is the case? What is the gender? Why does the adjective have this ending? This active analysis builds the pattern recognition you need.
Do not memorize charts in isolation. Learn adjective-noun combinations as chunks: kaltes Wasser, ein alter Freund, die schöne Stadt. Phrases stick better than abstract rules.
If you are still building your German grammar foundations, make sure you are comfortable with the four cases and article system first. Adjective endings build directly on that knowledge.
Master these three rules, and you have conquered one of the trickiest parts of German grammar.
