Questions & Answers about Ich hätte gern mehr Kontakte, mit denen ich darüber diskutieren kann.
Why do we use denen here instead of die?
denen is the dative plural relative pronoun. It refers back to the plural noun Kontakte (contacts). We must use the dative case here because the preposition mit always requires the dative.
Why is the verb kann at the very end of the sentence?
The section starting with mit denen is a relative clause. In German, relative clauses always push the conjugated verb (which is kann in this case) to the very end of the sentence.
What does darüber mean and why do we use it?
darüber translates to "about it" or "about this". In German, when a preposition like über refers to an abstract idea or a thing (not a person), you combine da- (there) and the preposition. The -r- is added in the middle because über starts with a vowel, making it easier to pronounce.
Why does the sentence start with Ich hätte gern instead of Ich habe gern?
hätte is a special form used to express wishes. Together with gern, Ich hätte gern means "I would like to have". If you said Ich habe gern, it would mean "I like having", which states a fact rather than a wish.
