Breakdown of Unter dem Sofa liegt noch eine Murmel von gestern.
Questions & Answers about Unter dem Sofa liegt noch eine Murmel von gestern.
Because unter dem Sofa describes a location: the marble is under the sofa, not moving there.
With two-way prepositions like unter, German uses:
- dative for location
- accusative for direction/movement toward a place
So:
- unter dem Sofa = under the sofa (already there)
- unter das Sofa = to under the sofa / underneath the sofa (moving there)
Here the marble is simply lying there, so dative is required: dem Sofa.
This is because German follows the verb-second rule in main clauses.
The first position can be taken by many different elements, not just the subject. Here, Unter dem Sofa is placed first to emphasize the location. Once that happens, the finite verb must still stay in second position, so it comes next:
- Unter dem Sofa = position 1
- liegt = position 2
- noch eine Murmel von gestern = the rest of the sentence
A more basic order would be:
Eine Murmel von gestern liegt noch unter dem Sofa.
Both are grammatical, but the original sentence puts more focus on where the marble is.
