“This” can only be used for things and people in the definition of related proposals. “Das” can be used as a relative pronoun to link two clauses. Today we will focus on just one of them: “this” as a relative pronoun. Relative clauses that are not defined complete the clause with additional information. It is not possible to replace the relative pronouns “who” and “what” with “this”. Relative clauses are those that contain essential information about someone or something. I wear the watch I bought last week = I wear the watch I bought last week. Look at the following two relative indefinite clauses = The book I am reading right now is very good. The book I’m reading right now is very good. My best friend is the girl at the end of the course who wears glasses = My best friend is the girl at the end of the course who wears glasses. The word “it” has many different uses in English. Normally I don’t make mistakes with this subject because Spanish grammar works in the same way as English, jejejejejeje.
