Questions & Answers about Der Algorithmus filtert den Inhalt für diejenigen, die mich kennen.
Why do we use diejenigen here and how is its ending decided?
diejenigen translates to "those" and is used to point forward to the relative clause die mich kennen ("who know me"). It is plural because it refers to a group of people. The ending is determined by the preposition für, which always requires the accusative case. Since it is accusative plural, the first part is the definite article die and the second part gets the standard plural weak adjective ending -en, combining into diejenigen.
Since diejenigen is in the accusative case after für, why is the relative pronoun die in the nominative case?
The case of a relative pronoun depends on its job inside its own clause, not the main clause. In the main clause, diejenigen is indeed accusative. But in the relative clause die mich kennen, the pronoun die acts as the subject (the people who are doing the knowing). Therefore, it must take the nominative case.
Why is it den Inhalt and not der Inhalt?
The noun Inhalt (content) is masculine (der Inhalt). In this sentence, it is the direct object that the algorithm is filtering. Direct objects take the accusative case, so der changes to den.
Why is it mich instead of mir in the relative clause?
