Det er sandsynligt, at bussen kommer lige om lidt.

Here det is a dummy subject, just like English it in It is likely that....

So:

• Det er sandsynligt = It is likely
• at bussen kommer lige om lidt = that the bus will arrive very soon

The det does not refer to a specific thing. It is there because Danish, like English, usually wants a subject in the sentence.

Sandsynligt means likely or probable.

It is the neuter singular form of the adjective sandsynlig.

Why is it sandsynligt here?

Because it goes with det, and when an adjective describes det, it usually takes the -t form:

• Det er sandsynligt = It is likely
• compare: en sandsynlig forklaring = a likely explanation

So this is normal adjective agreement.

At here means that and introduces a subordinate clause:

• Det er sandsynligt, at ...
• It is likely that ...

The clause after at gives the content of what is likely:

• at bussen kommer lige om lidt

In everyday English, that is often omitted, but in Danish at is very commonly kept in this kind of sentence.

The comma marks the start of the subordinate clause:

• Det er sandsynligt, at bussen kommer lige om lidt.

In Danish, comma use before subordinate clauses can depend on comma style. Many learners will see both:

• Det er sandsynligt, at bussen kommer lige om lidt.
• Det er sandsynligt at bussen kommer lige om lidt.

So if you see the comma here, that is normal. It separates the main clause from the at-clause.

Because bus is a common-gender noun:

• indefinite: en bus = a bus
• definite: bussen = the bus

For many common-gender nouns, the definite form is made by adding -en:

• en stol → stolen
• en bil → bilen
• en bus → bussen

The double s stays because the word already ends in s, and then -en is added.

Because after at, Danish uses normal subordinate-clause word order, and the subject usually comes before the verb:

• at bussen kommer
• that the bus is coming / will come

So:

• bussen = subject
• kommer = verb

This is the expected order here.

Danish often uses the present tense to talk about the future, especially when the future event is expected, planned, or clearly understood from context.

So:

• bussen kommer lige om lidt literally: the bus comes in just a little while naturally: the bus will be here very soon

English can do something similar in some cases, but Danish uses the present tense very often for future meaning.

Yes, sometimes, but it changes the feel a bit.

• bussen kommer lige om lidt = the bus is coming very soon / will arrive very soon
• bussen vil komme lige om lidt = the bus will come very soon

In Danish, kommer often sounds more natural here, because it describes an expected near-future event. Vil komme is possible, but can sound a bit heavier or less idiomatic in this exact context.

Lige om lidt is an idiomatic expression meaning:

• in a moment
• very soon
• in just a little while

The parts are:

• lige = just / exactly
• om lidt = in a little while

Together, lige om lidt means something like very soon or any moment now.

Both refer to the near future, but lige om lidt is a bit stronger and more immediate.

• om lidt = in a little while
• lige om lidt = very soon / in just a moment

So lige adds a sense of immediacy.

Yes. That is a very common alternative.

Compare:

• Det er sandsynligt, at bussen kommer lige om lidt.
• Bussen kommer sandsynligvis lige om lidt.

Both mean roughly the same thing:

• It is likely that the bus will arrive very soon.
• The bus will probably arrive very soon.

The difference is mostly stylistic:

• det er sandsynligt, at ... sounds a bit more formal or analytical
• sandsynligvis is often more direct and natural in everyday speech

No. They are related, but they are different parts of speech.

• sandsynlig / sandsynligt = likely → adjective
• sandsynligvis = probably / likely → adverb

Examples:

• Det er sandsynligt. = It is likely.
• Bussen kommer sandsynligvis snart. = The bus will probably arrive soon.

So in your sentence, sandsynligt describes the whole situation as likely.

Yes. A common alternative is:

• Bussen kommer lige om lidt, det er sandsynligt.

But this sounds less natural in many situations.

The original:

• Det er sandsynligt, at bussen kommer lige om lidt.

is the most straightforward way to say It is likely that the bus will arrive very soon.

If you want a more natural everyday version, Danish speakers might often prefer:

• Bussen kommer nok lige om lidt.
• Bussen kommer sandsynligvis lige om lidt.

In speech, the structure is the same, but the sentence may sound a little formal because of det er sandsynligt.

In everyday conversation, many speakers would more likely say:

• Bussen kommer nok lige om lidt.
• Bussen er der nok lige om lidt.
• Den kommer sandsynligvis lige om lidt.

So the given sentence is correct, but slightly more formal or written in tone than the most casual spoken Danish.

Yes, very much so.

The Danish structure matches the English one closely:

• Det = It
• er sandsynligt = is likely
• at = that
• bussen kommer lige om lidt = the bus will arrive very soon

So this is a useful sentence because the overall grammar is quite similar to English, even though some details, like the present tense kommer, work a little differently.
