Wij lopen haastig naar het station, want de trein komt straks aan.

Both wij and we mean we.

• we is more common in everyday speech.
• wij is a bit more formal or emphatic.

So Wij lopen haastig naar het station and We lopen haastig naar het station are both correct. In normal conversation, many speakers would probably say We lopen...

Haastig is an adverb here, describing how we are walking: hastily.

In Dutch, adverbs often come after the verb in a simple main clause:

• Wij lopen haastig naar het station.

That word order sounds natural. Dutch is often a bit more flexible than English, but this is the most straightforward pattern here:

• subject: Wij
• verb: lopen
• adverb: haastig
• destination: naar het station

You may also hear other word orders for emphasis, but this version is the neutral one.

It is close, but not exactly the same.

Haastig means something like:

• hastily
• in a hurry
• hurriedly

It suggests urgency, not just speed. So it is more like walking because you are rushed, not simply because you walk fast.

Related word:

• haast = haste / hurry

Naar is the usual preposition for movement toward a place: to / toward.

So:

• naar het station = to the station

This is different from location:

• op het station = at the station
• in het station = in the station

Because the sentence talks about going in the direction of the station, naar is the correct choice.

Because station is a het-word in Dutch.

Dutch nouns take either:

• de
• het

There is no simple rule that always tells you which one a noun takes, so learners often just have to memorize it with the noun:

• het station
• het huis
• de trein
• de stad

It is a good habit to learn every noun together with its article.

Want means because / for, and it introduces a reason.

In this sentence:

• Wij lopen haastig naar het station, want de trein komt straks aan.

= We are walking hastily to the station, because the train will arrive soon.

A very important grammar point:

• want does not change the normal word order of the clause after it.
• omdat usually sends the verb to the end.

Compare:

• ..., want de trein komt straks aan.
• ..., omdat de trein straks aankomt.

Both are correct, but the structure changes.

Because the verb is aankomen, a separable verb.

Its parts are:

• aan
  • komen

In a main clause, the conjugated verb goes to the usual verb position, and the prefix moves to the end:

• De trein komt straks aan.

This is very common in Dutch:

• opstaan → Ik sta vroeg op.
• meebrengen → Zij brengt koffie mee.
• aankomen → De trein komt aan.

So komt ... aan is not two separate verbs in meaning; together they form aankomen.

Because this is a main clause introduced by want.

In Dutch main clauses, the finite verb usually comes in second position:

• de trein = first element
• komt = finite verb in second position
• straks
• aan

So:

• de trein komt straks aan

The form aankomt at the end would belong to a subordinate-clause pattern, such as after omdat:

• ..., omdat de trein straks aankomt.

That is one of the biggest word-order differences learners notice in Dutch.

Straks usually means something like:

• soon
• in a little while
• sometimes later

In this sentence, it means the train is arriving before long.

Be careful: straks is a bit flexible in Dutch. Depending on context, it can mean:

• very soon
• later today
• in a little while

Here, the idea is clearly soon, because it explains why the speakers are hurrying.

Dutch often uses the present tense for near-future events, just like English does.

Compare English:

• The train arrives soon
• The train is arriving soon

Dutch does the same:

• De trein komt straks aan.

You could also use a future construction with zal, but it is often unnecessary:

• De trein zal straks aankomen.

That sounds more like a prediction or a more formal statement. The simple present is the most natural choice here.

Because want connects two independent clauses, and Dutch normally places a comma before it.

So this is standard punctuation:

• Wij lopen haastig naar het station, want de trein komt straks aan.

The comma helps show that the second part gives the reason for the first part.

Yes, absolutely. That is also correct and natural.

The difference is mostly grammatical structure and sometimes style:

• ..., want de trein komt straks aan.
• ..., omdat de trein straks aankomt.

Key difference:

• after want: normal main-clause order
• after omdat: subordinate-clause order, with aankomt at the end

Both mean basically the same thing here.

Literally, lopen means to walk. In this sentence, the image is clearly that the speakers are going on foot.

So:

• Wij lopen naar het station = We are walking to the station

Dutch can sometimes use lopen in slightly broader ways, but here it is best understood literally as walking. If they were just going to the station without specifying how, Dutch might use another verb depending on context, such as gaan.

Yes, that is grammatically possible, but it sounds more marked or literary.

Dutch main clauses follow the verb-second rule, so if you move Haastig to the front, the verb must still come second:

• Haastig lopen wij naar het station...

That version emphasizes haastig. The original sentence is more neutral and natural for everyday use:

• Wij lopen haastig naar het station...
