Nominative and accusative cases (AQA GCSE German): Revision Notes
Nominative and accusative cases
Understanding the German case system is essential for speaking and writing accurately. The case system shows the relationship between different parts of a sentence, helping you identify who is doing what to whom. Once you grasp these concepts, your confidence in German will grow significantly.
What are cases?
Cases in German tell us the role that nouns, pronouns, and articles play in a sentence. Think of cases as job descriptions - they show whether a word is the subject (doing the action) or the direct object (receiving the action).
The German case system might seem complex at first, but think of it like assigning roles in a play. Each noun gets a specific role (case) that tells you exactly what job it's doing in the sentence. This system actually makes German more precise than English in showing relationships between words.
The two most fundamental cases are nominative and accusative.
The nominative case
The nominative case identifies the subject of a sentence - the person, animal, or thing that performs the action of the verb. When you want to know who or what is doing something, you're looking for the nominative case.
How to recognise the nominative case
The nominative case answers the question "wer?" (who?) or "was?" (what?). It's the form you'll find in dictionaries and the one used after the verb "sein" (to be).
Key grammar points
The verb "sein" always takes the nominative case because it doesn't transfer action to an object - it simply describes or identifies the subject. For example, when you say someone "is" something, both the subject and the description use nominative case.
The accusative case
The accusative case identifies the direct object of a sentence - the person, animal, or thing that receives the action of the verb. This case shows what or whom the action is being done to.
How to recognise the accusative case
The accusative case answers the question "wen?" (whom?) or "was?" (what?). It's used when the verb transfers its action directly onto something or someone else.
Key grammar points
The phrase "es gibt" (there is/there are) always uses the accusative case because it introduces something new into the conversation. Think of "es gibt" as presenting or offering something, which requires the accusative case.
Useful vocabulary
| German | English | Case |

Article and pronoun changes
Understanding how articles and pronouns change between nominative and accusative cases is crucial for accurate German. This is where many learners make their most common mistakes.
Critical Rule: Only masculine articles and pronouns change form in the accusative case. Feminine, neuter, and plural forms stay exactly the same!
Definite articles (the)
- Masculine: der (nominative) → den (accusative)
- Feminine: die (nominative) → die (accusative) - no change
- Neuter: das (nominative) → das (accusative) - no change
- Plural: die (nominative) → die (accusative) - no change
Indefinite articles (a/an)
- Masculine: ein (nominative) → einen (accusative)
- Feminine: eine (nominative) → eine (accusative) - no change
- Neuter: ein (nominative) → ein (accusative) - no change
Possessive pronouns
Similar patterns apply to possessive pronouns like mein/dein/sein:
- Masculine: mein → meinen (accusative)
- Feminine and neuter: no change in accusative
Example sentences with translations
Worked Examples: Identifying Cases
Nominative examples (subjects):
- Der Schüler lernt Deutsch. (The student learns German.)
- Meine Schwester wohnt in Berlin. (My sister lives in Berlin.)
- Das Buch ist interessant. (The book is interesting.)
Accusative examples (direct objects):
- Ich sehe den Hund. (I see the dog.)
- Sie kauft einen Computer. (She buys a computer.)
- Es gibt eine Bäckerei hier. (There is a bakery here.)
Grammar and pronunciation tips
Helpful Learning Tips:
- Remember that only masculine articles and pronouns change in the accusative case
- The question words also change: "wer?" (who?) becomes "wen?" (whom?) in accusative
- When using "es gibt", always follow with accusative case
- Practice identifying whether words are subjects (nominative) or direct objects (accusative) in sentences
- A good trick: if you can ask "who or what is doing the action?" - that's nominative. If you ask "who or what is receiving the action?" - that's accusative.
Translation practice
Practice Exercise: Case Recognition
German to English:
- Der Junge findet den Ball.
- Es gibt einen Park in der Stadt.

- The boy finds the ball.

Key Points to Remember:
- Nominative case is for subjects - who or what does the action
- Accusative case is for direct objects - who or what receives the action
- Only masculine articles and pronouns change form in accusative (der→den, ein→einen)
- "Sein" always uses nominative case because it doesn't transfer action
- "Es gibt" always uses accusative case when introducing something new
- Feminine, neuter, and plural forms never change between nominative and accusative
