Questions & Answers about Ska vi köpa den svarta brödrosten eller den vita?
Why is there no Swedish word for "one" in den vita?
In English, we use the placeholder word "one" to avoid repeating the noun (the white one). In Swedish, you simply drop the noun completely and use the freestanding definite article (den) with the definite form of the adjective (vita).
Why do the adjectives svarta and vita end in "-a"?
Because they are in the definite form. Whenever you use the freestanding definite articles den, det, or de to point out specific things, the adjective that follows must take the definite -a ending.
Why does the first half say den svarta brödrosten instead of just den svarta brödrost?
This is the Swedish "double definite" rule. When an adjective describes a specific noun, you use the freestanding definite article (den) AND you keep the definite ending on the noun itself (-en).
I thought borde meant "should". Why use ska here?
While borde means "ought to" or "should" in the sense of a strong recommendation or advice, ska is used when asking for instructions, making a joint decision, or offering a suggestion (much like "shall we" in English).
