Jeg håber, at bussen ikke er forsinket, så jeg ikke kommer for sent til mødet.

After håber, Danish often uses at to introduce the next clause, just like English that in I hope that....

So:

Jeg håber, at bussen ikke er forsinket.

literally has the structure I hope that the bus is not delayed.

In everyday speech, at is often left out:

Jeg håber bussen ikke er forsinket.

That sounds natural too. In writing, especially careful or neutral writing, keeping at is very common.

Because this is a subordinate clause.

In a main clause, Danish usually puts ikke after the finite verb:

Bussen er ikke forsinket.

But in a subordinate clause, ikke normally comes before the finite verb:

... at bussen ikke er forsinket

So this is a very important word-order pattern:

• main clause: verb + ikke
• subordinate clause: ikke + verb

For the same reason: så here introduces another subordinate clause, so it follows subordinate-clause word order.

That is why Danish says:

... så jeg ikke kommer for sent

with ikke before kommer.

Compare that with a main clause:

Jeg kommer ikke for sent.

So both parts after at and after så show the same subordinate pattern.

Here it means so or so that, not then.

It introduces the result or intended outcome:

I hope the bus isn’t delayed, so that I won’t be late...

In other contexts, så can also mean then, but not in this sentence.

So in this example, it connects two ideas:

• the bus is not delayed
• as a result, I am not late

Because Danish often uses the present tense for future meaning when the context already makes the time clear.

So:

jeg ikke kommer for sent til mødet

means something like I won’t be late for the meeting, even though kommer is formally present tense.

This is very normal in Danish. For example:

Jeg kommer i morgen. = I’m coming tomorrow.

English does something similar, but Danish does it even more freely.

They are related, but they are not the same.

• forsinket = delayed
• for sent = late

So:

• Bussen er forsinket = the bus is delayed
• Jeg kommer for sent = I arrive late

In this sentence, the bus is the thing that may be delayed, and the speaker is the one who may end up late.

Because Danish uses the preposition til after komme for sent when you say what someone is late for.

So the pattern is:

komme for sent til noget

Examples:

• komme for sent til mødet
• komme for sent til skole
• komme for sent til festen

This is just the normal construction Danish uses.

Because mødet is the definite form: the meeting.

The sentence is talking about a specific meeting that is already known from the situation. That is why Danish uses:

til mødet = to/for the meeting

If it were any meeting, not a specific one, you could say:

til et møde = to a meeting

So the definite form tells you this is a particular meeting, not just any meeting.

Yes. That is very natural, especially in speech and informal writing.

So both of these are possible:

• Jeg håber, at bussen ikke er forsinket...
• Jeg håber bussen ikke er forsinket...

The version with at can sound a bit more explicit or slightly more formal in writing, but both are standard.

Importantly, even when at is omitted, the clause still keeps subordinate word order:

bussen ikke er forsinket, not bussen er ikke forsinket.

The commas are there because the sentence contains subordinate clauses.

You will often see:

Jeg håber, at bussen ikke er forsinket, så jeg ikke kommer for sent til mødet.

But Danish comma usage can vary a little depending on the comma system being used. In particular, the comma before at is often omitted in modern writing:

Jeg håber at bussen ikke er forsinket, så jeg ikke kommer for sent til mødet.

So the first comma is somewhat style-dependent. The comma before så is very common because it clearly separates the next clause.

For a learner, the main thing to notice is not the punctuation, but the word order after at and så.
