Questions & Answers about Været er ekstremt kaldt.
Vær means weather as a noun in its basic dictionary form.
Været is the definite singular form, literally the weather. In Norwegian, when talking about the weather in a general or current sense, the definite form is very common.
So:
- vær = weather
- været = the weather
In this sentence, været sounds natural because it refers to the weather as the thing being discussed right now.
Norwegian usually marks definiteness by adding an ending to the noun.
For neuter nouns like vær, the definite singular ending is often -et:
- et vær = a weather condition / a spell of weather
- været = the weather
This is one of the big differences from English. Instead of a separate article like the, Norwegian often attaches definiteness directly to the noun.
