Questions & Answers about Legen behandler sykdommen.
The ending -en is the definite singular ending in Bokmål for many nouns.
- lege = doctor
legen = the doctor
- sykdom = disease / illness
- sykdommen = the disease / the illness
So instead of using a separate word like English the, Norwegian often adds the definiteness to the end of the noun.
In Norwegian, the definite article is usually attached to the noun as a suffix.
So English:
- the doctor
- the disease
becomes Norwegian:
- legen
- sykdommen
This is very normal in Norwegian. A separate article can appear in some other structures, especially with adjectives, but not in this simple sentence.
