Bussen kommer lige om lidt.

Because bussen means the bus.

In Danish, the definite article is often attached to the end of the noun instead of being a separate word:

• en bus = a bus
• bussen = the bus

So the ending -en here is the singular definite ending.

Lige om lidt is a very common Danish expression meaning very soon, in just a moment, or in a little while.

You can think of it in parts:

• om lidt = in a little while
• lige adds a sense like just or right

So lige om lidt feels a bit like any minute now or in just a moment.

Danish very often uses the present tense to talk about the near future, especially when the context already makes the time clear.

So:

• Bussen kommer lige om lidt = The bus is coming soon / The bus will be here in a moment

This is completely natural in Danish. English does something similar with The bus is coming soon.

Grammatically, yes, but it usually sounds less natural in this situation.

Vil komme can mean will come, but in everyday Danish, the simple present is usually preferred for scheduled or expected near-future events:

• natural: Bussen kommer lige om lidt
• less natural here: Bussen vil komme lige om lidt

So learners should usually choose the present tense in sentences like this.

The basic word order is:

subject + verb + time expression

So here:

• Bussen = subject
• kommer = verb
• lige om lidt = time expression

This is a normal main-clause pattern in Danish.

Yes. Danish often moves time expressions to the front, but then the verb must stay in second position.

So you can say:

• Lige om lidt kommer bussen

That is also correct. Notice that kommer comes before bussen because Danish main clauses follow the verb-second rule.

Yes, absolutely.

• Bussen kommer om lidt = The bus is coming in a little while
• Bussen kommer lige om lidt = The bus is coming very soon / in just a moment

Adding lige makes it sound a bit more immediate and idiomatic.

Both can mean soon, but there is a small difference in feeling:

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

So lige om lidt often sounds more immediate than snart.

For example:

• Bussen kommer snart = The bus is coming soon
• Bussen kommer lige om lidt = The bus is coming any moment now

In time expressions, om often means in, as in after this amount of time from now.

Examples:

• om lidt = in a little while
• om fem minutter = in five minutes
• om et øjeblik = in a moment

So in this sentence, om marks time from the present moment forward.

A rough guide for an English speaker is:

• Bussen ≈ BOO-sen
• kommer ≈ KOM-er
• lige ≈ LEE-uh or LEE-eh
• om lidt ≈ om LILT

A few notes:

• The u in bus is not like English bus. It is closer to oo in many learners' ears.
• kommer has a soft, unstressed ending.
• lige is often pronounced quite lightly in normal speech.
• In fast speech, the whole sentence can sound smoother and less clearly separated than the spelling suggests.

In context, it usually means the bus will arrive soon.

The verb komme literally means come, but with transport it often refers to arrival:

• Bussen kommer klokken 8 = The bus arrives at 8
• Toget kommer snart = The train is arriving soon

So in everyday use, kommer often works like is coming / is arriving.

No. Danish does not capitalize all nouns.

So it is:

• Bussen kommer lige om lidt

not:

• Bussen Kommer Lige Om Lidt

Only the first word of the sentence and proper names are capitalized.
