Adjective Endings after Definite Articles

1.Endings after the definite article

After the definite article der / die / das and its case forms den, dem, des, der, the adjective almost always needs only two endings: -e or -en. That is why this system is much simpler than it first appears.

2.Why the definite article simplifies the task

The definite article already carries a lot of grammatical information: gender, number, and case. Forms such as der, die, das, den, dem, des often show this clearly. So the adjective does not have to carry all of that information alone. The system therefore reduces mainly to -e and -en.

3.Main rule

After the definite article: Nominative singular is usually -e; Accusative singular feminine and neuter are also -e; everything else is -en.

-e appears only in a few “light” positions. Almost everywhere else you find -en.

4.Full table

This table is the centre of the whole topic.

5.The pattern inside the table

There are only five cells with -e: Nominative singular masculine / feminine / neuter and Accusative singular feminine / neuter. All other cells have -en.

6.Nominative: masculine, feminine, neuter, plural

In Nominative singular after the definite article the adjective takes -e. In the plural after die it already takes -en, not -e.

7.Nominative singular and plural side by side

Nominative singular is the typical -e zone. Plural already belongs to the large -en zone.

8.Accusative masculine: den neuen Tisch

Here you see the most important difference from Nominative. In the masculine the form changes clearly: der neue Tisch → den neuen Tisch. Pattern: den + adjective-en.

Feminine and neuter look the same in Nominative and Accusative, so Accusative masculine is especially important at A2.

9.Accusative: feminine, neuter, plural

Feminine and neuter stay in the -e group. Plural uses -en.

10.Dative: -en everywhere

After the definite article the adjective in the Dative always takes -en — for all genders and for plural. That is a property of the Dative, not a separate rule for each gender.

In Dative plural the noun often also takes -n: die Kinder → den kleinen Kindern, die Freunde → den alten Freunden. That is a property of Dative plural, not of the adjective ending.

11.Genitive: also -en everywhere

In the Genitive after the definite article the adjective also always takes -en. The adjective ending is very regular across the whole Genitive.

Masculine and neuter nouns often take a separate Genitive ending -(e)s: that is the noun ending, separate from the adjective's -en.

12.Ultra-short memory rule

After the definite article almost always -en. Only five cells have -e: Nominative singular masculine, feminine, and neuter; Accusative singular feminine and neuter. That is often easier than learning 16 forms separately.

13.Why this is called weak declension

After the definite article people traditionally speak of the weak adjective declension. The article already shows the main grammatical information, so the adjective only needs a weak, simple marker: -e or -en. Other endings are not needed in this system.

14.The article carries the main information

The article changes clearly (der / den / dem / des), while the adjective only switches between -e and -en. So it makes sense to identify the article and the case first.

15.Algorithm: case → article/gender → -e or -en

To form the ending: is there a definite article? which case? singular or plural? is this one of the five -e cells? If yes → -e; if no → -en.

Case is often determined by the verb or preposition. The article die alone is sometimes not enough: it can be feminine Nominative/Accusative or plural Nominative/Accusative. You also need number and the function in the sentence.

16.One adjective through four cases

With neu and nouns of different genders and number, the picture becomes clear.

Masculine has -e only in Nominative, then -en. Feminine and neuter: Nom/Acc → -e, Dat/Gen → -en. In the plural after the definite article the adjective always takes -en.

17.Several adjectives

If several attributive adjectives stand before one noun, they usually take the same weak ending.

18.sehr and other intensifiers

Words such as sehr, besonders, ziemlich, wirklich do not change the ending rule. The ending belongs to the adjective.

19.Comparative with the definite article

The comparative in attributive position is also declined. The comparative -er and the adjective ending are different elements: größ + er + e, bess + er + en.

20.Superlative with the definite article

The attributive superlative takes the normal weak ending. In the plural again -en.

21.Participles attributively

Participles before a noun are declined like ordinary adjectives.

22.hoch, teuer, dunkel

Some adjectives change their stem slightly when an ending is added. The ending itself is still chosen by the same -e / -en system.

23.After prepositions

Prepositions often determine the case and thereby help choose the adjective ending. The preposition sets the case; the case helps choose the ending.

24.Two-way prepositions

With two-way prepositions Accusative or Dative is possible. In the masculine the adjective has -en in both cases, so the case difference is especially clear in the article den / dem.

25.Contractions: im, am, zum, zur, beim, vom, ins

Definite articles often fuse with prepositions: in dem → im, an dem → am, zu dem → zum, zu der → zur, bei dem → beim, von dem → vom, in das → ins. This does not change the adjective rule: the hidden article form still determines the case.

26.dieser, jeder, welcher: the same logic

Words such as dieser, jeder, welcher, solcher largely behave like the definite article in the adjective-ending system.

If a determiner shows grammatical information as clearly as der / die / das, the adjective usually uses the weak declension.

27.alle in the plural

After alle the adjective in the plural usually takes -en. That matches the general plural pattern in this group.

28.Common mistakes

In the Genitive there are two different endings: -en on the adjective, and often -(e)s on masculine/neuter nouns. die alone is not enough: you need to know singular or plural. The form dem neuen Auto becomes clearer if you first identify: dem → Dative neuter → -en.

29.Short strategy

1. Is there a definite article? → yes.
2. Plural? → always -en.
3. Dative or Genitive? → always -en.
4. Accusative masculine? → -en.
5. Otherwise Nominative singular or Accusative feminine/neuter → -e.

That leaves very few positions to remember separately.

30.Learn the table as a model, not as 16 rules

It is inefficient to memorise all 16 cells independently. A better image: an island of -e (Nom. Sg. m/f/n and Acc. Sg. f/n) and a sea of -en (everything else). The table then becomes automatic much faster. After the definite article the adjective practically uses only -e and -en; the article often shows case more clearly than the adjective ending; prepositions help determine case.

31.Comparison with predicative use

Predicatively there is no ending. Attributively the ending appears only because the adjective stands directly before the noun.

After der / die / das and their case forms the adjective almost always ends in -en. -e remains only in Nominative singular and in Accusative singular feminine and neuter.
