Questions & Answers about Ich freue mich darüber, dass das Spa fantastisch ist.
Why do we need darüber here instead of just saying Ich freue mich, dass...?
Verbs that take a fixed preposition, like sich freuen über (to be happy about), need a bridge when they connect to a dass (that) clause. The da-compound darüber acts as a placeholder in the main sentence for the information coming in the dass clause. While you might hear native speakers drop it in casual speech, it is grammatically expected in written German!
Could I use darauf instead of darüber in this sentence?
That would change the meaning! Sich freuen über means you are happy about something happening right now or in the past. Sich freuen auf means you are looking forward to something in the future. Because the spa is currently fantastic, you need darüber.
Why is the verb ist at the very end of the sentence?
The word dass is a subordinating conjunction. This means it creates a dependent clause and kicks the conjugated verb all the way to the end of that clause. So, instead of the normal word order, the ist gets pushed to the very end.
Why is mich included in this sentence?
