Ifølge lægen er alt normalt.

Ifølge means according to. It is a preposition, so it is followed by a noun or pronoun:

• ifølge lægen = according to the doctor
• ifølge ham = according to him

It is a very common way to show the source of information.

Lægen is the definite form and means the doctor.

In Danish, the definite article is usually added to the end of the noun:

• læge = doctor
• lægen = the doctor

So ifølge lægen means according to the doctor, not according to a doctor.

This is because Danish main clauses normally follow the verb-second rule.

That means the finite verb must come in the second position. Here, Ifølge lægen is placed first, so the verb er must come next:

• Ifølge lægen = first element
• er = second element
• alt = subject
• normalt = complement

So:

• Ifølge lægen er alt normalt. ✓
• Ifølge lægen alt er normalt. ✗

This word order is very important in Danish.

Alt means everything or all of it. In this sentence, it is the subject.

Useful comparison:

• alt = everything / all of it
• alle = everyone / all (plural)

So here alt is the natural choice because the sentence is talking about the overall situation: everything is normal.

Because normalt agrees with alt, which is grammatically neuter singular.

In Danish, adjectives often change form depending on the noun or pronoun they describe:

• en normal dag = a normal day
• et normalt barn = a normal child
• alt er normalt = everything is normal

So the -t appears because alt behaves like a neuter singular subject.

Also, in this sentence normalt is not an adverb. It is an adjective used after er and agreeing with the subject.

Yes. Er is the present tense of at være = to be.

Examples:

• jeg er = I am
• du er = you are
• han er = he is
• alt er normalt = everything is normal

Unlike English, Danish does not change the present tense form for different persons. It is always er.

Yes, that is also correct.

Both sentences mean basically the same thing, but the emphasis is slightly different:

• Ifølge lægen er alt normalt.
  Emphasis on the source: according to the doctor
• Alt er normalt ifølge lægen.
  Emphasis first on the statement: everything is normal

Both are natural Danish.

Normalt is a subject complement (also called a predicative adjective). It describes the subject alt after the verb er.

So the structure is:

• alt = subject
• er = linking verb
• normalt = description of the subject

This is similar to English sentences like:

• The house is big
• Everything is normal

A learner often notices that g is not pronounced like a hard English g here.

In lægen, the g is softened, so the word sounds roughly like LAY-yen or LEH-yen, depending on how simplified you want the approximation to be.

A few useful points:

• æ is a vowel sound not found exactly in English
• the g is soft, almost like a y
• the ending -en is the definite ending meaning the

So the spelling may look harder than the actual spoken form.

Yes, it is completely natural and idiomatic.

It sounds like something you would say when reporting medical information or reassurance, for example after a check-up or test result.

It is neutral in tone and very common in everyday as well as professional contexts.
