Questions & Answers about Über dieses Angebot muss ich lange nachdenken.
Wait, I thought this lesson was about da-compounds like "darüber". Why don't we use one here?
Da-compounds (like darüber) replace a preposition + noun, or they point forward to a whole clause. Here, the specific thing you are thinking about is explicitly named as a noun phrase: dieses Angebot. If you wanted to point to a full idea using a dass-clause (which is the focus of this lesson), you would use the da-compound darüber to anticipate it: Ich muss lange darüber nachdenken, dass du mir dieses Angebot gemacht hast (I have to think for a long time about the fact that you made me this offer). But for a simple noun phrase, we just use the preposition über + the noun.
Why does nachdenken take the preposition über? Doesn't über mean "over" or "above"?
In German, the verb nachdenken (to think about / to ponder) always pairs with the preposition über. Prepositions often don't translate literally between languages. Just like in English you say "think about", in German you must memorize the fixed combination nachdenken über.
Is dieses Angebot in the accusative or dative case here?
It is in the accusative case. Über is a two-way preposition, meaning it can take either the dative or the accusative depending on context. However, when it is used as a fixed preposition with a specific verb (like nachdenken über, sprechen über, or sich freuen über), it always forces the accusative case. Since das Angebot is a neuter noun, the accusative form is dieses Angebot.
Why does the sentence start with Über dieses Angebot instead of Ich?
German allows you to put the most emphasized part of the sentence in the first position. By putting Über dieses Angebot at the front, the speaker is highlighting this specific offer. Because the conjugated verb (muss) is strictly locked into the second position, the subject (ich) has to slide to the third position right after it.
Why is nachdenken written as one word at the very end? Isn't it a separable verb?
You are right that nachdenken is a separable verb. Normally, the prefix would split off and go to the end (for example: Ich denke lange nach). However, because this sentence uses the modal verb muss (must / have to), the main verb gets pushed to the very end of the sentence in its full infinitive form. When a separable verb is in the infinitive, its prefix always stays attached.
