Fyren står ved døren.

Because -en is the Danish definite ending for many common-gender nouns.

• en fyr = a guy
• fyren = the guy

So fyr is the basic noun, and fyren means the guy.

Fyr usually means guy, fellow, or bloke in everyday language. It is a common, informal word for a male person.

Depending on context, it can sound:

• neutral: a guy
• casual: a bloke
• sometimes slightly colloquial or conversational

In this sentence, fyren simply means the guy.

For the same reason as fyren: Danish often adds the definite article to the end of the noun.

• en dør = a door
• døren = the door

So ved døren means by the door or at the door.

Står is the present tense of stå, which means to stand.

• at stå = to stand
• står = stands / is standing

In Danish, the present tense often covers both ideas:

• The guy stands by the door
• The guy is standing by the door

Both are natural translations depending on context.

Because Danish often uses the simple present where English might prefer the present continuous.

So:

• Fyren står ved døren can mean The guy stands by the door
• but in normal English, it is often more natural to say The guy is standing by the door

Danish does have ways to emphasize ongoing action, but very often the plain present tense is enough.

Ved usually means by, at, near, or next to, depending on context.

In ved døren, it means something like:

• by the door
• at the door
• near the door

It shows location. The exact English preposition can vary, but the idea is that the guy is positioned close to the door.

This is the normal Danish sentence pattern for a simple statement:

subject + verb + other information

So:

• Fyren = subject
• står = verb
• ved døren = location

This is very similar to basic English word order:

• The guy
  • is standing
    • by the door

The ø sound does not exist exactly in English, so it can be tricky.

A rough guide:

• ø is a front rounded vowel
• you make a sound somewhat like eh or uh, but with rounded lips

So dør is not like English door, even though the meanings are related.

Also, Danish pronunciation is often softer than spelling suggests, so learners usually need to hear native audio to get comfortable with words like dør and døren.

No, not usually.

• ved døren = by the door / at the door / near the door
• i døren = in the doorway / in the door

So ved døren means the person is located close to the door, while i døren suggests being in the doorway itself.

It is neutral and completely natural Danish.

The only slightly informal element is fyr, because it means guy rather than something more formal like manden (the man).

So:

• Fyren står ved døren = natural, everyday speech
• not rude
• not especially formal
