Prepositional relative clauses
Relative clauses add extra details about a noun. When the verb in the relative clause requires a preposition, or when you describe a location or tool (like the studio you record in, or the cable you connect with), the preposition sits at the very beginning of the relative clause.
Place a comma, followed immediately by the preposition and the relative pronoun, and send the conjugated verb to the end.
The noun described determines the pronoun's gender and number, but the preposition determines its case.
Dative relative pronouns (Location and means)
Prepositions like mit, von, and aus always take the Dative case. Two-way prepositions (in, an, auf) also take the Dative when describing a static location (answering "where?").
The Dative relative pronouns are dem (masculine/neuter), der (feminine), and denen (plural).
Here, das Studio is a neuter noun, and in indicates location, so we use in dem:
| The studio we are recording in is very expensive. | Das Studio, in dem wir aufnehmen, ist sehr teuer. |
Similarly, working at a mixing desk is a static location:
| I need the mixing desk you are currently working at. | Ich brauche das Mischpult, an dem du gerade arbeitest. |
When describing a tool you use to accomplish something, mit always takes the Dative:
| We are looking for a long cable we can connect the amplifier with. | Wir suchen ein langes Kabel, mit dem wir den Verstärker anschließen können. |
| I bought the speaker the music comes from. | Ich kaufte den Lautsprecher, aus dem die Musik kommt. |
Accusative relative pronouns (Direction and targets)
Prepositions like ohne and für always take the Accusative case. Two-way prepositions shift to the Accusative when they describe a direction, movement, or targeted action (answering "where to?").
The Accusative relative pronouns are den (masculine), die (feminine/plural), and das (neuter).
Because ohne strictly requires the Accusative, the masculine noun Kopfhörer takes den:
| Where are the headphones I hear nothing without? | Wo ist der Kopfhörer, ohne den ich nichts höre? |
Notice how the two-way preposition an behaves differently here than it did with the mixing desk above. Because plugging headphones into a computer is a directed action, an triggers the Accusative:
| The computer I connect the headphones to is not working. | Der Computer, an den ich den Kopfhörer anschließe, funktioniert nicht. |
Looking onto a screen is also a targeted direction:
| There is the screen I always look at. | Dort ist der Bildschirm, auf den ich immer schaue. |
And für always takes the Accusative:
| The speaker we paid a lot of money for is broken. | Der Lautsprecher, für den wir viel Geld bezahlten, ist kaputt. |
