Questions & Answers about Wij hebben oude meubels in de opslag staan.
Why do we add staan at the end instead of just saying Wij hebben oude meubels in de opslag?
You could leave it out, but Dutch speakers strongly prefer using posture verbs to describe how something occupies a space. Because furniture rests on a base, staan is the natural choice. Using this 'hebben + object + location + posture verb' structure emphasizes the physical presence of the items in that location.
Could staan go somewhere else in the sentence, for example right after hebben?
No, in this specific construction the posture verb must go at the very end of the clause. The fixed order is hebben + direct object (oude meubels) + location (in de opslag) + bare infinitive posture verb (staan).
English uses the uncountable word 'furniture'. Why is it plural (meubels) here, and could I use meubilair instead?
In Dutch, meubel is a countable noun meaning 'a piece of furniture', so the plural meubels is very common. You could indeed use the uncountable collective noun meubilair instead. If you did, the sentence would be Wij hebben oud meubilair in de opslag staan.
Why does the adjective oude get an -e at the end in this sentence?
