Questions & Answers about Alle Möbel in meiner Wohnung sind hell und modern.

Why is there no article before Möbel?

Because alle functions as a determiner here, so you don’t need an extra article. If you remove alle, you could say die Möbel (“the furniture”). In German Möbel is a plural-only noun, so with alle you simply say alle Möbel (“all furniture”).

What case is meiner Wohnung in, and why?

It’s in the dative case. When in indicates a static location (answering “where?”), it takes the dative. Wohnung is feminine (die Wohnung), and the dative singular form of mein for feminine nouns is meiner. Hence in meiner Wohnung.

Why are the adjectives hell and modern not inflected here?

They are predicative adjectives: they follow the verb sein (“to be”) and describe the subject rather than directly modifying a noun. Predicative adjectives in German remain uninflected:
– Die Möbel sind hell und modern.
If you used them attributively (before a noun), you would add endings (e.g. helle Möbel).

Why do we use sind instead of ist?
