Questions & Answers about Wir haben das Möbelstück gekauft, weil es riesengroß und bildschön ist.
How do the compound adjectives riesengroß and bildschön intensify the meaning here?
They use a noun prefix to exaggerate the adjective! riesengroß combines der Riese (the giant) and groß (big) to mean gigantic. bildschön combines das Bild (the picture) and schön (beautiful) to mean "picture-beautiful" or gorgeous. This is a very common way to create strong, vivid adjectives in German.
Do I need to capitalize the noun parts of these compounds?
No. Even though Riese and Bild are capitalized when used on their own as nouns, they have become parts of a new adjective here. Because German adjectives are written in lowercase, the resulting compound words are completely lowercase: riesengroß and bildschön.
Why use das Möbelstück instead of just das Möbel?
While the base word Möbel exists, it is almost exclusively used in the plural (die Möbel) to talk about furniture collectively. When you want to point out one single, specific piece of furniture, you attach -stück (piece) to create the singular noun das Möbelstück.
Why does the subordinate clause use es instead of er or sie?
