German Adjective Endings Without the Fear
The topic learners dread, reduced to one question and three small tables — plus the shortcut that gets you right most of the time while you learn.
Adjective endings are where many learners stall. The tables look brutal, so people memorise them, forget them, and go back to avoiding adjectives entirely.
Here is a more useful way in: the ending depends on one question — how much information the article already gives.
The one question that decides everything
German only needs to mark gender and case once. If the article already does it, the adjective can relax. If not, the adjective must do the work.
Article does the work
der, die, das, dieser… → adjective takes a weak ending: -e or -en. Nothing else exists.
Article is vague
ein, kein, mein… → adjective must show gender itself: ein guter Mann.
No article at all
Adjective takes the full article ending: guter Kaffee, kaltes Wasser.
Case 1: after der/die/das (weak endings)
This is the easiest one, and the best news in German grammar: there are only two endings, -e and -en.
| m | f | n | pl | |
|---|---|---|---|---|
| Nominativ | der gute Mann | die gute Frau | das gute Kind | die guten Leute |
| Akkusativ | den guten Mann | die gute Frau | das gute Kind | die guten Leute |
| Dativ | dem guten Mann | der guten Frau | dem guten Kind | den guten Leuten |
The 5 / rest shortcut
After der/die/das there are exactly five -e forms — the three nominative singulars plus feminine and neuter accusative. Everything else is -en. Learn the five, default to -en.
Case 2: after ein/kein/mein (mixed endings)
The problem: ein could be masculine or neuter, so the adjective has to disambiguate. In exactly three places it borrows the strong ending.
ein guter Mann
-er shows masculine nominative
ein gutes Kind
-es shows neuter nominative/accusative
Everywhere else
identical to the der/die/das table above
So: ein guter Mann, but den guten Mann and einen guten Mann are the same. Only three forms to add.
Case 3: no article (strong endings)
With no article, the adjective takes over the article's job and copies its ending.
| m | f | n | pl | |
|---|---|---|---|---|
| Nominativ | guter Kaffee | kalte Milch | kaltes Wasser | gute Leute |
| Akkusativ | guten Kaffee | kalte Milch | kaltes Wasser | gute Leute |
| Dativ | gutem Kaffee | kalter Milch | kaltem Wasser | guten Leuten |
You meet this most with food, drink and abstract nouns: Ich trinke gerne schwarzen Kaffee.
The survival shortcut
While you are still learning, this rough rule gets you right a surprising amount of the time:
Default to -en when unsure. It is the single most common ending by a wide margin.
A wrong adjective ending almost never blocks understanding. Avoiding adjectives entirely, however, makes your German sound flat. Guess and keep talking.
How to actually get fluent with these
- Do not memorise all three tables at once. Start with der/die/das — five -e forms, rest -en.
- Add the three ein exceptions: guter (m), gutes (n), and that is it.
- Learn phrases whole: ein guter Freund, mit freundlichen Grüßen, schwarzen Kaffee.
- Notice them while reading rather than drilling them in isolation.
- Say them out loud — the rhythm of ein guter Mann eventually feels wrong when you get it wrong.

Why do German adjectives change their endings?
German marks gender, case and number once per noun phrase. If the article already shows that information (der, die, das), the adjective takes a simple weak ending. If the article is ambiguous (ein) or missing, the adjective carries that information instead.
What is the difference between der gute Mann and ein guter Mann?
Der already shows masculine nominative, so the adjective takes the weak ending -e. Ein could be masculine or neuter, so the adjective must show the gender itself with the strong ending -er.
What is the easiest way to learn German adjective endings?
Start with the der/die/das table, where only two endings exist: five -e forms and -en everywhere else. Then add the three ein exceptions (-er for masculine nominative, -es for neuter). Learn common phrases whole rather than memorising all three tables at once.
Which German adjective ending is most common?
-en is by far the most frequent. If you are unsure mid-sentence, -en is the best guess and is very often correct.
