Jeg har travlt, så jeg må skynde mig til stationen.

At have travlt is the normal Danish expression for to be busy / to be in a hurry.

So:

• Jeg har travlt = I’m busy / I’m in a hurry

You can sometimes see er travl, but it is less natural in this kind of everyday sentence. It can sound more like describing someone as a generally busy person, rather than saying they are busy right now.

So for this sentence, har travlt is the standard choice.

Travlt comes from the adjective travl.

Forms include:

• travl = busy
• travlt = neuter form / form used in the fixed expression have travlt

In jeg har travlt, you should really learn har travlt as a whole expression. Danish uses it idiomatically, so it is best not to translate it word-for-word.

Here så means so or therefore.

The sentence is:

• Jeg har travlt, så jeg må skynde mig til stationen.
• I’m in a hurry, so I have to hurry to the station.

It connects the two ideas:

1. I’m in a hurry
2. therefore I must hurry to the station

So så is showing result or consequence.

Because here så is working like so/therefore and joining two main clauses.

After this kind of så, Danish normally keeps normal main-clause word order:

• så jeg må skynde mig ...

That means:

• subject: jeg
• finite verb: må

If så meant more like then, Danish often uses inversion:

• Så må jeg skynde mig. = Then I must hurry.

So both patterns exist, but they mean slightly different things and are structured differently.

In this sentence, må means must / have to.

So:

• jeg må skynde mig = I must hurry / I have to hurry

This is important because må can also mean may / be allowed to in other contexts:

• Må jeg gå? = May I leave?

So må has more than one meaning. In your sentence, the context clearly makes it mean must.

Sometimes yes, but the nuance changes.

• må = must, have to, necessity
• skal = shall, am supposed to, am going to, obligation or plan

In this sentence, må fits well because the speaker feels pressure or necessity:

• I’m in a hurry, so I must hurry to the station

If you said jeg skal skynde mig, it could sound more like:

• I’m supposed to hurry
• I need to hurry
• I should get moving

So skal is possible in some situations, but må is stronger and more natural here.

Because må is a modal verb, and modal verbs in Danish are followed by a bare infinitive, without at.

So:

• jeg må skynde mig
• not jeg må at skynde mig

This is like English:

• I must hurry
• not I must to hurry

Other common Danish modal verbs work the same way:

• kan = can
• skal = shall / must
• vil = will / want to
• bør = ought to

Because the verb is at skynde sig, a reflexive verb.

That means Danish says something like:

• to hurry oneself

So:

• jeg skynder mig = I hurry
• du skynder dig = you hurry
• han skynder sig = he hurries

In your sentence:

• jeg må skynde mig = I must hurry

The reflexive pronoun changes with the subject:

• mig for jeg
• dig for du
• sig for han/hun/man/de in many cases
• os for vi
• jer for I

Because til shows movement toward a destination.

• til stationen = to the station

If you said på stationen, that would usually mean:

• at the station / on the station premises

So compare:

• Jeg går til stationen. = I’m going to the station.
• Jeg er på stationen. = I’m at the station.

In your sentence, the speaker is moving toward the station, so til is the correct preposition.

Because Danish usually puts the definite article at the end of the noun.

So:

• en station = a station
• stationen = the station

That -en is the equivalent of English the.

In this sentence, stationen probably refers to a specific station that is understood from the situation, so the definite form is natural.

The sentence is in the present tense.

• har = present tense of have
• må = present tense of måtte / modal må
• skynde = infinitive, used after the modal verb

So the whole sentence means something happening now.

A past version would be:

• Jeg havde travlt, så jeg måtte skynde mig til stationen.
• I was in a hurry, so I had to hurry to the station.

Yes, a comma is natural here because the sentence contains two clauses:

1. Jeg har travlt
2. så jeg må skynde mig til stationen

Each clause has its own subject and finite verb:

• jeg har
• jeg må

So the comma helps separate the two parts clearly.

Yes, in this sentence you normally do.

You have two separate clauses, so each one needs its own subject:

• Jeg har travlt, så jeg må skynde mig til stationen.

Leaving out the second jeg would not be the normal structure here.

So even though English also repeats the subject, this is still worth noticing in Danish: after så introducing a new clause, you normally keep the subject explicit.
