Trykkbandasjen stopper blødningen.

Because Norwegian usually writes compound nouns as a single word.

So trykkbandasjen is built from:

• trykk = pressure
• bandasje = bandage

Together, trykkbandasje means pressure bandage, and trykkbandasjen means the pressure bandage.

This is very normal in Norwegian. Where English often uses two words, Norwegian often uses one:

• sykehus = hospital
• fotballkamp = football match
• trykkbandasje = pressure bandage

The ending -en marks the noun as definite singular: the pressure bandage.

The basic form is:

• en trykkbandasje = a pressure bandage

The definite form is:

• trykkbandasjen = the pressure bandage

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

Because Norwegian usually puts definiteness on the noun itself.

Compare:

• en bandasje = a bandage
• bandasjen = the bandage

So instead of saying a separate word like English the, Norwegian often uses an ending such as -en, -a, or -et, depending on the noun.

In this sentence:

• trykkbandasjen = the pressure bandage
• blødningen = the bleeding

Stopper is the present tense of the verb å stoppe.

So:

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

In Norwegian, the present tense does not change depending on the subject:

• jeg stopper = I stop
• du stopper = you stop
• han stopper = he stops
• trykkbandasjen stopper = the pressure bandage stops

That is simpler than English, where we say stop but stops with he/it.

Because the sentence is talking about the specific bleeding involved in the situation, not just bleeding in general.

Compare:

• stopper blødning = stops bleeding / stops bleeding in a general sense
• stopper blødningen = stops the bleeding

Both kinds of expression can exist, but blødningen sounds like a concrete, specific case: the bleeding from this wound.

The basic form is blødning.

So:

• en blødning = a bleeding / a hemorrhage
• blødningen = the bleeding

The word comes from the verb å blø = to bleed.

This is a very common pattern in Norwegian:

• verb + noun related to the action

For example:

• å blø = to bleed
• blødning = bleeding

Yes, in this sentence the word order is very similar to English:

• Trykkbandasjen = subject
• stopper = verb
• blødningen = object

So the structure is:

Subject + Verb + Object

That is one reason this sentence feels quite straightforward to English speakers.

Yes. That would mean A pressure bandage stops the bleeding.

The difference is:

• Trykkbandasjen stopper blødningen = The pressure bandage stops the bleeding
• En trykkbandasje stopper blødningen = A pressure bandage stops the bleeding

So the original sentence refers to a specific pressure bandage, while the version with en is less specific.

Not normally in standard, natural Norwegian if you mean a full ordinary sentence about a specific situation.

Why not?

Because Norwegian usually expects nouns to be marked for indefiniteness or definiteness:

• en trykkbandasje / trykkbandasjen
• en blødning / blødningen

So Trykkbandasje stopper blødning sounds unnatural as a normal sentence. You might see something shorter like that in notes, headings, or very compressed medical language, but not as standard everyday grammar.

The head noun is bandasje, which is usually masculine in Bokmål:

• en bandasje
• bandasjen

Because trykkbandasje is a compound with bandasje at the end, the whole compound follows that noun’s gender:

• en trykkbandasje
• trykkbandasjen

In Norwegian compounds, the last part usually determines the gender and inflection.

This is a Bokmål issue of noun gender usage.

Many nouns that can be feminine in Bokmål are often also written with masculine-style endings. So a noun like blødning can appear as:

• blødningen and sometimes, depending on style and usage,
• blødninga

In standard Bokmål, -en is very common and completely normal. So blødningen is nothing unusual.

A rough guide is:

TRYKK-ban-DA-sjen

A few useful points:

• trykk has a short vowel and a strong kk
• y in Norwegian is not like English y; it is a rounded front vowel, somewhat difficult for English speakers
• sj in -sjen sounds like English sh

So the last part -sjen sounds roughly like shen.

You do not need a perfect accent right away; the most important thing is to notice that sj = sh and that the word stress falls naturally on the earlier part of the compound.

Å stoppe can be both.

Transitive:

• Trykkbandasjen stopper blødningen = The pressure bandage stops the bleeding

Intransitive:

• Blødningen stopper = The bleeding stops

So Norwegian uses å stoppe much like English to stop. It can mean either stop something or come to a stop depending on context.

It is most naturally read as Bokmål.

Clues include forms like:

• stopper
• blødningen

A Nynorsk version might look different, for example with forms such as stansar or a different definite ending depending on the wording chosen.

So if you are learning standard Norwegian from most beginner materials, this sentence fits well with Bokmål.
