Questions & Answers about Wer im Club streitet, den werfe ich hinaus.
Why do we use den in the second half of the sentence if the first half uses wer?
The first part uses wer (whoever) in the nominative case because that person is the subject doing the arguing. But in the main clause, this same person is being thrown out. They become the direct object of the verb hinauswerfen. Therefore, the pronoun pointing back to them must be in the accusative case, which is den.
Can I leave out den and just say "Wer im Club streitet, werfe ich hinaus"?
No, it is required here. When a free relative clause with wer comes first, and the person's grammatical case changes between the clauses (here, from nominative to accusative), you must use a demonstrative pronoun like den to anchor them in the main clause. It is like saying "Whoever argues, that person I throw out."
Why is the verb werfe placed immediately after den?
In German main clauses, the conjugated verb must sit in the second position. The entire relative clause and its pointer pronoun (Wer im Club streitet, den) act together as one large block taking up the first position. To keep the verb in position two, werfe must immediately follow it.
Why is hinaus pushed all the way to the end of the sentence?
