Questions & Answers about Boken har en lang tittel.
Boken is the definite singular form of bok.
- bok = book / a book
- boken = the book
In Norwegian, the definite article is often attached to the end of the noun instead of being a separate word.
So:
- en bok = a book
- boken = the book
That is why the sentence starts with Boken.
The ending -en is a common definite singular ending for nouns that take en in the indefinite form.
Here the pattern is:
- en bok = a book
- boken = the book
This is very common in Bokmål:
- en bil → bilen
- en hund → hunden
- en stol → stolen
So -en here works like English the, but attached to the noun.
