|Basic patterns in German language:
Relative pronouns in German:
A noun is a word used to
name a person, an object, an abstract quality
or a concept and a personal pronoun stands in for a noun, usually for a
or thing. Relative pronouns (in a relative clause) are pronouns refer
to a noun in the main clause.
Relative pronouns are
used to begin a relative clause - relative pronouns
are words that correspond to "who, whom or that " in English
A comma is always in front of the relative pronoun, which is put into
correct gender depending on the noun it refers to.
The verb (in the relative clause) goes to the end of the sentence.
Relative pronouns have the same gender as the nouns they refer (main
English: This is the book that I bought last week
German: Dies ist das Buch, das ich letzte Woche gekauft habe.
The book (German: das Buch) is neuter in German, the realtive pronoun
refers to "the book" and is the subject (-> Nom. case) in the
clause. So you take the "das" as the right form.
