Sometimes you want to add extra information about a person or thing you're talking about. In German, you can do this with a relative clause. It's a short phrase that starts with a word like 'der', 'die', or 'das' and has its verb at the very end.

Let's start with the nominative case. You use this when the person or thing you're describing is doing the action in the extra phrase. The relative pronoun acts like 'who' or 'that' and must match the gender of the noun. For example, 'Das ist der Mann, der hier wohnt' means 'That is the man who lives here'.

For plural nouns in the nominative, the relative pronoun is always 'die', no matter the gender of the individual nouns. For instance, 'Das sind die Kinder, die im Garten spielen' means 'Those are the children who are playing in the garden'.
