Questions & Answers about De slingers zijn boven de dansvloer opgehangen.
Why does this sentence use zijn instead of worden?
Because it describes a state, not an ongoing action. This is called the state passive. The action of hanging the garlands is already finished, and we are describing the result: they are currently hanging there. If you used worden (De slingers worden opgehangen), it would mean they are being hung right now by someone.
Could zijn ... opgehangen also translate to "have been hung"?
Yes! In Dutch, the state passive ("are hung") and the present perfect passive ("have been hung") are built exactly the same way: with zijn + the past participle. Context tells you if the speaker is emphasizing the recent completion of the action or the current state, but the real-world meaning is basically the same.
Why does the past participle have -ge- in the middle of the word (opgehangen)?
Because the infinitive is ophangen (to hang up), which is a separable verb. For separable verbs, the ge- prefix used for past participles gets sandwiched between the separable prefix (op) and the main verb (hangen).
Could I just say De slingers hangen boven de dansvloer instead?
