Questions & Answers about Die Spieler hören ohne das Headset nichts voneinander.
What exactly is voneinander and how is it built?
It is a reciprocal prepositional adverb, which is just a grammar term for combining a preposition with einander (each other). Here, the preposition von (from) fuses with einander to create voneinander (from each other). Always write these as a single word!
Why is the preposition von used in voneinander here?
The preposition is determined by the verb. To say you hear from someone in German, you use the phrase hören von. Since we want to say the players hear 'from' each other, we use von as the base for voneinander.
Could I use the reflexive pronoun and say von sich instead?
No, that would change the meaning entirely! If you said they hear nothing von sich, it would mean each player doesn't hear their own voice. When the action goes back and forth between multiple people (person A hears person B, and vice versa), you must use the reciprocal word einander.
Why is it das Headset after the preposition ohne? Shouldn't it be dative?
Not all prepositions take the dative case. The preposition ohne (without) is one of the strict 'accusative-only' prepositions. Since Headset is a neuter noun, the article remains das in the accusative case.
