THE SHORT VERSION
Start with these three ideas. Then test them in real German sentences.
In nominative singular, definite articles are der, die, das. Indefinite articles are ein for masculine/neuter and eine for feminine.
A masculine direct object changes der → den and ein → einen: “Ich sehe den Mann.” Feminine and neuter definite articles keep their nominative form in accusative singular.
After a dative preposition like mit, use dem (masculine/neuter), der (feminine), or den (plural): “mit dem Mann”.
Der Mann kommt. → masculine subject: nominative
Ich sehe den Mann. → masculine direct object: accusative
Ich spreche mit dem Mann. → mit takes dative
The plural dative noun may also gain -n where its plural form allows it: mit den Kindern.A CLOSER LOOK
First identify the noun’s gender and number. Then identify its role or the preposition governing it. Those two choices determine the article form.
| Case | Masculine | Feminine | Neuter | Plural |
|---|---|---|---|---|
| Nominative | der | die | das | die |
| Accusative | den | die | das | die |
| Dative | dem | der | dem | den |
| Genitive | des | der | des | der |

Introduce a new thing with ein/eine: “Hier ist ein Hund.” Refer to that known dog with der: “Der Hund schläft.” Singular indefinite forms include ein Mann → einen Mann → einem Mann (nominative → accusative → dative). There is no plural ein; use a bare plural or words such as keine or meine.
Try this: Ask: Is this noun the subject, a direct object, or governed by a preposition such as mit? Then choose the case.
