Questions & Answers about Motlyset er kraftig.
Because Norwegian usually writes compound nouns as a single word.
Here, motlys is a compound made from:
- mot = against / toward
- lys = light
So motlys is a fixed noun meaning backlight, glare, or light coming from the front/against you depending on context. When it becomes definite, you get motlyset.
The -et is the definite ending for a singular neuter noun in Bokmål.
So the pattern is:
- et motlys = a backlight / a glare
- motlyset = the backlight / the glare
This is very common in Norwegian. Instead of usually adding a separate word like English the, Norwegian often adds the definite article to the end of the noun.
Motlys is a neuter noun, which is why you say:
- et motlys
- motlyset
That neuter gender also helps explain other grammar around the noun.
