Lægen siger, at akut smerte kræver behandling.

Læge means doctor, while lægen means the doctor.

In Danish, the definite article is often attached to the end of the noun:

• en læge = a doctor
• lægen = the doctor

So lægen siger means the doctor says.

Siger means says or is saying. It is the present tense of sige = to say.

Danish present tense verbs usually end in -r:

• at sige = to say
• siger = says / is saying

So:

• Lægen siger = The doctor says

Here at means that and introduces a subordinate clause:

• Lægen siger, at ... = The doctor says that ...

In English, that is often optional:

• The doctor says acute pain requires treatment
• The doctor says that acute pain requires treatment

In Danish, at is very normal here, especially in writing.

The comma is there because at akut smerte kræver behandling is a subordinate clause.

In Danish, you will often see a comma before subordinate clauses introduced by words like at, fordi, som, and hvis.

However, this is also one of those places where Danish comma usage can vary depending on the comma system being used. So learners may also see:

• Lægen siger, at akut smerte kræver behandling.
• Lægen siger at akut smerte kræver behandling.

Both may occur, but the version with the comma is very common in teaching materials.

Because akut smerte is being used in a general, abstract sense, similar to English acute pain.

The sentence is not talking about one specific pain; it is making a general statement about the condition or phenomenon. That is why Danish can simply say:

• akut smerte = acute pain

If you wanted to refer to one specific instance, you could use an article:

• en akut smerte = an acute pain / a specific acute pain

But in medical or general statements, leaving out the article is very natural.

Because the adjective is in its basic form here.

Akutte is typically used in plural or definite forms, for example:

• akutte smerter = acute pains
• den akutte smerte = the acute pain

But in akut smerte, the phrase is singular and indefinite in a general sense, so akut is the correct form.

This is something learners often just have to get used to by seeing many examples.

Because the sentence is talking about pain as a general concept, not several separate pains.

Compare:

• smerte = pain (general/abstract)
• smerter = pains / pain symptoms

So:

• akut smerte kræver behandling = a general statement about acute pain
• akutte smerter kræver behandling = a statement about acute pains / pain symptoms in plural

Both are possible Danish, but they mean slightly different things.

Kræver means requires.

So kræver behandling means requires treatment.

It is a fairly strong word. It suggests that treatment is necessary, not just helpful.

Compare:

• kræver = requires
• behøver = needs
• har brug for = has need of / needs

In a medical sentence, kræver sounds precise and formal, which fits well here.

Because behandling is being used as an uncountable or general noun here: treatment in general, not a treatment.

So:

• kræver behandling = requires treatment
• kræver en behandling = requires a treatment or one treatment

In English, this works the same way:

• requires treatment sounds general and natural
• requires a treatment sounds more specific and less natural in many contexts

The word order is:

• at = subordinating conjunction
• akut smerte = subject
• kræver = verb
• behandling = object

So it follows the basic pattern:

at + subject + verb + object

That is very normal for a subordinate clause in Danish.

A useful thing to know is that Danish main clauses and subordinate clauses behave differently. In a main clause, Danish often follows the verb-second pattern. In a subordinate clause introduced by at, the structure is more straightforward.

For example:

• Lægen siger, at akut smerte kræver behandling.

If you add ikke, you get:

• Lægen siger, at akut smerte ikke kræver behandling.

Notice that ikke comes before the finite verb in the subordinate clause pattern learners need to get used to.

In standard written Danish, at is normally kept in this kind of sentence.

English often says:

• The doctor says acute pain requires treatment

But Danish usually prefers:

• Lægen siger, at akut smerte kræver behandling.

Leaving out at would usually sound less standard, especially in careful writing. For learners, it is safest to include it.
