Politiet stopper den voldelige mannen.

In Norwegian, the definite article is often attached to the end of the noun instead of being a separate word.

So:

• politi = police
• politiet = the police

The ending -et is the definite ending here. English says the police with a separate article, but Norwegian often builds definiteness into the noun itself.

In Norwegian, politiet is usually treated as a collective singular noun. That is why the verb is singular:

• Politiet stopper ... = The police stop/is stopping ...

English and Norwegian do not always handle collective nouns the same way. In Norwegian, this is completely normal.

Stopper is the present tense of stoppe.

• å stoppe = to stop
• stopper = stop / is stopping

A useful thing for English speakers: Norwegian verbs do not change according to the subject.

So you get:

• jeg stopper
• du stopper
• han stopper
• vi stopper

The verb form stays the same.

Because Norwegian normally uses den/det/de before a definite noun with an adjective.

So when you say the violent man, Norwegian usually wants:

• den
  • adjective + definite noun

That gives:

• den voldelige mannen

This is a very common pattern in Norwegian.

Yes, in a way it does — and that is normal in Norwegian. This is often called double definiteness.

Compare:

• mannen = the man
• den voldelige mannen = the violent man

When there is no adjective, Norwegian can just use the definite noun:

• mannen

When there is an adjective before the noun, Norwegian usually uses both:

• den
  • adjective + noun in definite form

So den voldelige mannen is not redundant by Norwegian standards; it is the standard structure.

Because adjectives often change form in Norwegian depending on the grammar around them.

Here, the noun phrase is definite: the violent man. In definite noun phrases, the adjective usually takes -e:

• en voldelig mann = a violent man
• den voldelige mannen = the violent man

So the -e on voldelige is there because the phrase is definite.

It can in some contexts, but here it is best understood as part of the normal definite structure, not as a strong demonstrative.

So:

• den voldelige mannen usually means the violent man

If you strongly stress den, context might make it feel more like that violent man, but in ordinary grammar here, it is mainly just the required article in the definite phrase.

Because of word order.

This sentence follows the normal Norwegian pattern:

• Subject + verb + object

So:

• Politiet = subject
• stopper = verb
• den voldelige mannen = object

Norwegian nouns usually do not show subject/object roles with special endings the way some languages do. Instead, word order does a lot of that work.

No. It would reverse the roles.

• Politiet stopper den voldelige mannen = The police stop the violent man
• Den voldelige mannen stopper politiet = The violent man stops the police

Because Norwegian relies heavily on word order, switching the noun phrases changes who is doing the action.

Because mannen is the definite singular form of mann.

• mann = man
• en mann = a man
• mannen = the man

In the sentence, we need the violent man, not a violent man, so the definite form mannen is required.
