Denne goes with en-words, dette with et-words and disse in the plural, and the noun after them usually stays in the definite form: denne skjorta. To ask a price, say Hva koster det?
Examples
- Hva koster denne skjorta?
- How much is this shirt?
- Jeg tar denne, ikke den.
- I'll take this one, not that one.
- Hva koster skoene?
- How much are the shoes?
The mistake to avoid
Norwegian marks the noun twice here - denne skjorta, with the definite ending kept.
Where this fits in
Food & ordering, Norwegian A1: Order at a café or restaurant, ask for the bill, and talk about basic food and drink.
