Går De ligeud til udgangen, ser De metroens indgang på venstre side.

Because Danish can omit hvis (if) in certain conditional sentences.

So:

Går De ligeud til udgangen, ser De metroens indgang ...

means the same as:

Hvis De går ligeud til udgangen, ser De metroens indgang ...

Literally, this is like Go you straight ahead to the exit, see you the metro entrance..., but in natural English it means If you go straight ahead to the exit, you will see the metro entrance...

This verb-first structure is quite common in formal instructions and directions.

De is the formal word for you in Danish.

It is capitalized to show respect and formality. This is similar to older or more formal systems in some other European languages.

In modern everyday Danish, people usually say du instead of De, unless they are being especially formal or old-fashioned.

So this sentence has a polite, formal tone, like something you might hear from staff, in announcements, or in written customer-facing language.

It can technically be used as a formal singular or plural you, depending on context.

In this sentence, it most likely means formal singular you, but the form itself can also address more than one person politely.

That is one reason De can feel a little different for English speakers: English you does not show this distinction clearly either, but Danish informal speech usually does it with du (singular) and I (plural), while De is the formal version.

Ligeud means straight ahead or straight on.

It is commonly used in directions. So:

Gå ligeud = Go straight ahead

It does not just mean directly in a vague sense here; it specifically refers to moving forward without turning.

They are two related but opposite nouns:

• udgang = exit
• indgang = entrance

In the sentence:

• til udgangen = to the exit
• metroens indgang = the metro entrance / the entrance to the metro

This is very common in Danish signs and directions, so it is useful to learn the pair together.

Udgangen is the definite singular form of udgang.

The forms are:

• en udgang = an exit
• udgangen = the exit
• udgange = exits
• udgangene = the exits

Danish often adds the definite article to the end of the noun, instead of using a separate word like English the.

So udgangen literally contains the idea of the exit in one word.

Both are possible.

Metroens indgang literally means the metro's entrance, but in natural English we would usually say the metro entrance or the entrance to the metro.

This is the Danish -s genitive, where you add -s to a noun in the definite form:

• metroen = the metro
• metroens = the metro's

So:

metroens indgang = the metro's entrance / the entrance to the metro

Danish often uses this structure where English might prefer of or to phrasing.

Yes, absolutely.

These are both natural:

• metroens indgang
• indgangen til metroen

They are very close in meaning. The version in your sentence is a little more compact and typical of formal directional language.

A learner should understand both.

The comma separates the two clauses:

• Går De ligeud til udgangen
• ser De metroens indgang på venstre side

The first clause gives the condition, and the second gives the result.

In other words:

If you go straight ahead to the exit, you will see the metro entrance on the left-hand side.

Danish comma rules can differ somewhat from English comma habits, but here the comma is marking the boundary between the conditional part and the main result.

Because Danish main clauses normally place the finite verb in the second position.

In the second clause, nothing comes before the verb, so the verb comes first:

ser De metroens indgang ...

If something else were placed first, the subject would come after the verb, for example:

På venstre side ser De metroens indgang.

This is a very important Danish pattern called V2 word order.

So even though English would usually say you see, Danish often has word order patterns that depend on what comes first in the clause.

På venstre side means on the left side or on the left-hand side.

Yes, it is very close to til venstre, which means to the left.

In many situations, they are interchangeable:

• på venstre side = on the left-hand side
• til venstre = to the left

The version with side can sound a little more explicit or spatially descriptive.

Yes, but it sounds formal and a bit like written or official direction-giving language.

A more everyday spoken version might use du instead of De, for example:

Går du ligeud til udgangen, ser du metroens indgang på venstre side.

Or someone might simply say:

Gå ligeud til udgangen. Metroens indgang er på venstre side.

So the original sentence is correct and natural, but it has a polite, formal tone.

No. Even though it begins with the verb, it is not a question here.

A real question would usually be spoken with question intonation and understood from context, for example:

Går De ligeud til udgangen?

That would mean Are you going straight ahead to the exit?

But in your sentence, the first clause is a conditional clause without hvis, so it means If you go..., not a question.

This is a common point of confusion for English speakers, because verb-first order can signal different things in Danish depending on context.
