Questions & Answers about Ich zeige dir den Parcours, den du heute machen musst.
Why is den used twice, once before the comma and once after?
They look identical, but they do different jobs! The first den is the accusative article for the masculine noun Parcours. The second den is a relative pronoun meaning "that" or "which." It is also masculine and accusative because it refers back to Parcours and acts as the direct object of the relative clause (the thing you "have to do").
Why does musst come after machen at the end of the sentence?
The comma introduces a relative clause (den du heute machen musst), which is a type of dependent clause. In German dependent clauses, the conjugated verb (here, the modal verb musst) is always pushed to the very end of the sentence, placing it after the infinitive verb (machen).
Why is it dir instead of dich?
The verb zeigen (to show) usually takes a dative indirect object for the person being shown something, and an accusative direct object for the thing being shown. Here, dir is the dative object ("to you") and den Parcours is the accusative direct object.
Since Parcours ends in an "s", how is it pronounced?
Parcours is a loanword from French. In its singular form, like it is used here, the final "s" is completely silent, so it sounds roughly like "par-koor."
