The German Case System
This section explains The German Case System. The German language uses a case system to show the function of nouns, pronouns, and adjectives in a sentence. There are four cases:
- Nominative – Subject of the sentence
 - Accusative – Direct object
 - Dative – Indirect object
 - Genitive – Possession
 
Each case affects articles (der/die/das), pronouns, and adjective endings.
The Nominative Case – Subject
The nominative case is used for the subject of the sentence (the person or thing doing the action).
🔹 Example Sentences (Foundation Tier)
- Der Hund schläft. (The dog is sleeping.)
 - Meine Schwester liest ein Buch. (My sister is reading a book.)
 
✅ Tip: To identify the nominative, ask: Who or what is doing the action?
| Definite Articles | Indefinite Articles | Pronouns | 
|---|---|---|
| der (masc.) | ein (masc.) | ich (I) | 
| die (fem.) | eine (fem.) | du (you) | 
| das (neut.) | ein (neut.) | er/sie/es (he/she/it) | 
| die (plural) | keine (plural) | wir/sie (we/they) | 
The Accusative Case – Direct Object
The accusative case is used for the direct object (the thing directly affected by the action).
🔹 Example Sentences (Foundation Tier)
- Ich habe einen Hund. (I have a dog.)
 - Er kauft eine Jacke. (He is buying a jacket.)
 
✅ Tip: To identify the accusative, ask: Who or what is receiving the action?
Changes in Articles (Accusative Case)
| Definite Articles | Indefinite Articles | Pronouns | 
|---|---|---|
| den (masc.) | einen (masc.) | mich (me) | 
| die (fem.) | eine (fem.) | dich (you) | 
| das (neut.) | ein (neut.) | ihn/sie/es (him/her/it) | 
| die (plural) | keine (plural) | uns/sie (us/them) | 
🚨 Key Rule: Only masculine nouns change (der → den, ein → einen). Feminine, neuter, and plural remain the same.
🔹 Higher-Tier Example:
- Ich sehe den alten Mann in der Stadt. (I see the old man in the city.)
 
The Dative Case – Indirect Object
The dative case is used for the indirect object (the recipient of the action).
🔹 Example Sentences (Foundation Tier)
- Ich gebe dem Lehrer einen Apfel. (I give the teacher an apple.)
 - Sie schreibt ihrer Freundin eine E-Mail. (She writes her friend an email.)
 
✅ Tip: To identify the dative, ask: To whom or for whom is something done?
Changes in Articles (Dative Case)
| Definite Articles | Indefinite Articles | Pronouns | 
|---|---|---|
| dem (masc.) | einem (masc.) | mir (to me) | 
| der (fem.) | einer (fem.) | dir (to you) | 
| dem (neut.) | einem (neut.) | ihm/ihr (to him/her) | 
| den (plural) (+n on noun) | keinen (plural) | uns/ihnen (to us/to them) | 
🚨 Key Rule: In the dative plural, add -n to the noun (e.g., "die Kinder" → "den Kindern").
🔹 Higher-Tier Example:
- Ich habe meinem kleinen Bruder ein Geschenk gekauft. (I bought my little brother a gift.)
 
The Genitive Case – Possession
The genitive case is used to show possession (like "of" or "’s" in English).
🔹 Example Sentences (Higher Tier)
- Das ist das Auto meines Vaters. (That is my father's car.)
 - Die Farbe des Himmels ist blau. (The colour of the sky is blue.)
 
✅ Tip: The genitive answers the question: Whose?
Changes in Articles (Genitive Case)
| Definite Articles | Indefinite Articles | 
|---|---|
| des (masc.) + -s | eines (masc.) + -s | 
| der (fem.) | einer (fem.) | 
| des (neut.) + -s | eines (neut.) + -s | 
| der (plural) | keiner (plural) | 
🚨 Key Rule: In masculine and neuter nouns, add "-s" or "-es" to the noun (e.g., "des Mannes" for "the man's").
🔹 Higher-Tier Example:
- Die Tür des Hauses ist geschlossen. (The door of the house is closed.)
