relativpronomen

Relativpronomen are words used in German to introduce relative clauses, which provide additional information about a noun or pronoun mentioned in the main clause. They connect the main clause to the subordinate relative clause and agree in gender and number with the noun they refer to. However, they take their case from their function within the relative clause. The most common relative pronouns are derived from the demonstrative pronoun "der, die, das."

The relative pronouns are der, die, das, welcher, welche, welches. "Der, die, das" are used in most situations and are identical in form to the definite articles, which can sometimes cause confusion. "Welcher, welche, welches" are also used and agree in gender and number with the antecedent. While "der, die, das" are generally preferred in formal writing, "welcher, welche, welches" can offer greater clarity, especially when the antecedent is ambiguous.

The case of the relative pronoun is determined by its role in the relative clause. For example, if the pronoun is the subject of the relative clause, it will be in the nominative case. If it is the direct object, it will be in the accusative case. If it indicates possession or is used with a preposition, it will be in the genitive or dative case, respectively. Understanding the grammatical function within the relative clause is key to correctly choosing the case of the relative pronoun.
