Relative clauses with der, die, das

What are relative clauses (Relativsätze) with der, die, das, den?

Relative clauses give extra information about a noun.

In German, they start with a relative pronoun: der, die, das, den.

• The relative pronoun refers back to a noun (the “antecedent”).
• It also shows the gender (m/f/n) and the case (here: nominative or accusative).

Example:

• Das ist der Mann, der im Park joggt.
  → der Mann = antecedent, der = relative pronoun, subject of the relative clause.

Step 1: One key question – subject or object?

To choose between der and den, you only need one question:

• Is the relative pronoun the subject in the relative clause?
  • If yes → use Nominativ.
  • If no (it is the direct object) → use Akkusativ.

How to check:

1. Look only at the relative clause (after the comma).
2. Ask: Who / what does the action? → subject.
3. If the relative pronoun is the subject → Nominativ.
   If the subject is another word (often ich, du, er, sie …) → the relative pronoun is object → Akkusativ.

Step 2: Gender and case – the mini-table you really need

For A2, we only need Nominativ and Akkusativ for Singular:

• Important: Only masculine changes: der → den.
• Feminine and neuter stay the same in nominative and accusative: die, das.

Step 3: When do you use Nominativ in the relative clause?

Use Nominativ when the relative pronoun is the subject of the relative clause.

• Der Mann, der im Park joggt, ist mein Nachbar.
  → Who jogs? der. (subject) → Nominativ der.
• Die Frau, die hier arbeitet, ist meine Chefin.
  → Who works here? die. (subject) → Nominativ die.
• Das Auto, das schnell fährt, gehört mir.
  → What drives fast? das. (subject) → Nominativ das.

Self-check:

• Can you replace the relative pronoun with er/sie/es and it is still the subject?
  → Then you need Nominativ.

Example:

• Der Mann, der im Park joggt. → Er joggt im Park. ✔

Step 4: When do you use Akkusativ in the relative clause?

Use Akkusativ when the relative pronoun is the direct object of the verb in the relative clause.

• Der Ball, den ich kaufe, ist teuer.
  → Who buys? ich (subject).
  → What do I buy? den (object) → Akkusativ den.
• Die Frau, die ich sehe, ist meine Lehrerin.
  → Who sees? ich (subject).
  → Whom do I see? die (object) → Akkusativ die (same form as nominative).
• Das Buch, das ich lese, ist spannend.
  → Who reads? ich (subject).
  → What do I read? das (object) → Akkusativ das (same form as nominative).

Self-check:

• In the relative clause, can you ask: “Whom / What + verb?” and the answer is the relative pronoun?
  → Then you need Akkusativ.

Step 5: Typical mistake – mixing up der and den

This is the most common problem. A mini checklist helps:

1. Is the noun you describe masculine? (der Mann, der Ausweis, der Polizist …)
2. Look at the relative clause only.
3. Who does the action?
   → If it is the relative pronoun → use der.
   → If it is another word (ich, du, er …) → use den.

Compare:

• Das ist der Polizist, der mir gestern geholfen hat.
  → Who helped? der (Polizist) → subject → der ✔
• Das ist der Polizist, den mir gestern geholfen hat.
  → Here the subject is also the policeman, so den is wrong.

• Ich suche den Ausweis, den ich gestern verloren habe.
  → Who lost it? ich → subject.
  → What did I lose? den (Ausweis) → object → den ✔
• Ich suche den Ausweis, der ich gestern verloren habe.
  → Here ich is subject, so der is wrong; we need accusative den.

Step 6: Feminine and neuter – stay relaxed

For feminine and neuter, nominative and accusative look the same.

• Feminine: always die
• Neuter: always das

Examples feminine:

• Das ist die Frau, die hier arbeitet. (subject)
• Das ist die Frau, die ich jeden Morgen sehe. (object, but still die)
• Das ist die Kreditkarte, die mir im Urlaub gestohlen wurde.

Examples neuter:

• Das ist das Formular, das die Botschaft heute schickt. (subject)
• Das ist das Formular, das du ausfüllen musst. (object, but still das)

Conclusion:

• For die and das, you do not see a form change between nominative and accusative.
• You still need to understand the function (subject/object), but the form stays the same.

Step 7: Word order in the relative clause

Relative clauses are subordinate clauses. That means:

• The finite verb goes to the end of the relative clause.

Pattern:

• main clause, relative pronoun + … + verb at the end.

Examples:

• Das ist der Mann, der im Park joggt.
• Ich suche den Ausweis, den ich gestern verloren habe.
• Das ist die E-Mail, die ich an meine Chefin schreibe.

Self-check:

• Is there a comma before the relative pronoun?
• Is the conjugated verb at the end of the relative clause?

Step 8: Building relative clauses step by step

Strategy to combine two sentences:

1. Identify the noun you want to describe (antecedent).
2. Decide its gender (der/die/das) from the article in the base form.
3. Look at the second sentence and ask:
   • Is this noun the subject in that sentence? → Nominativ.
   • Or is it the direct object? → Akkusativ.
4. Choose the correct relative pronoun from the mini-table.
5. Move the conjugated verb in the relative clause to the end.

Example 1:

• Base sentences:
  Das ist der Kollege.
  Der Kollege arbeitet im Homeoffice.
• Antecedent: der Kollege → masculine.
• In “Der Kollege arbeitet im Homeoffice” the colleague is subject.
• So we need der (Nominativ maskulin).
• Combined:
  Das ist der Kollege, der im Homeoffice arbeitet.

Example 2:

• Base sentences:
  Kennst du den Mann?
  Ich treffe den Mann heute Abend.
• Antecedent: den Mann → masculine.
• In “Ich treffe den Mann heute Abend” the subject is ich, object is den Mann.
• So we need den (Akkusativ maskulin).
• Combined:
  Kennst du den Mann, den ich heute Abend treffe?

Step 9: Quick self-check: did I choose the right form?

Use this checklist when you are unsure:

1. Underline the noun you describe.
   Example: Das ist der Ausweis, ___ ich brauche.
2. Find its gender from the article:
   der → masculine, die → feminine, das → neuter.
3. Look at the relative clause only and find the subject.
   Who / what does the action?
4. If the relative pronoun is the subject → use Nominativ: der/die/das.
5. If another word is the subject and the relative pronoun is object → use Akkusativ:
   • Masculine: den
   • Feminine: die
   • Neuter: das

Try it with this sentence:

• Der Gegenstand, ___ ich verloren habe, ist wichtig.
  → Subject in the relative clause: ich.
  → The item is object → Akkusativ, masculine → den.
  → Der Gegenstand, den ich verloren habe, ist wichtig.

Step 10: What should you pay special attention to?

• Form vs. function: Do not choose “der/den” only from the first sentence. Always analyse the function in the relative clause.
• Masculine nouns: This is where you really need to decide between der and den.
• Verb at the end: Remember to send the conjugated verb to the end of the relative clause.
• Comma: Put a comma before the relative pronoun.
• Practice with real contexts: Prefer sentences about your work, travel, documents, people you know:
  
  • Der Kollege, der mit mir im Büro sitzt, heißt Jens.
  • Die Präsentation, die ich morgen halte, ist wichtig.
  • Das Formular, das ich ausfüllen muss, ist kompliziert.

If you follow these steps, you can build and understand relative clauses with der, die, das, den confidently and use them in conversation.
