Questions & Answers about Verden er stor.
In Danish, the definite article is usually attached to the end of the noun.
- verden = the world
- en verden = a world
So the -en at the end is doing the job of English the. This is very common in Danish:
- bog = book
- bogen = the book
Since verden already includes the definite ending, you do not add a separate word for the in this sentence.
The noun is verden, but the full set of forms is useful to know:
- en verden = a world
- verden = the world
- verdener = worlds
- verdenerne = the worlds
So the noun is a common-gender noun, which matters for adjective agreement.
