Erstatningsbussen kommer etter innstillingen.

Because Norwegian usually writes compound nouns as a single word.

Here, the structure is:

• erstatning = replacement / compensation
• buss = bus
• -en = the definite ending, so the bus

So:

• erstatningsbuss = replacement bus
• erstatningsbussen = the replacement bus

English often writes this as two words, but Norwegian normally joins them.

That -s- is a linking sound used in many Norwegian compounds. It is often called a linking s.

So this is not a possessive s like in English. It is just part of how the compound is formed:

• erstatning
  • buss → erstatningsbuss

You cannot always predict perfectly when Norwegian uses this linking -s-, so it is often best to learn the whole compound as a word.

In Norwegian, the definite article is usually attached to the end of the noun instead of standing as a separate word.

So:

• buss = bus
• bussen = the bus

And:

• innstilling = cancellation
• innstillingen = the cancellation

That is why you do not see a separate word like English the before the nouns.

Kommer is the present tense of komme, which means to come.

So:

• jeg kommer = I come / I am coming
• bussen kommer = the bus comes / the bus is coming / the bus arrives

In Norwegian, the present tense is also very commonly used for scheduled future events, especially with transport, timetables, and plans.

So kommer can naturally be used even if the bus has not arrived yet.

Grammatically, it literally means comes, but in transport contexts English often translates it more naturally as arrives.

So in a sentence about a bus, kommer is often understood as:

• comes
• is coming
• arrives

The exact English choice depends on the translation style, but the Norwegian word is still kommer.

Because etter and etterpå do different jobs.

• etter is a preposition, so it is followed by a noun phrase
  
  • etter innstillingen = after the cancellation
• etterpå is an adverb, meaning afterwards or later
  
  • Erstatningsbussen kommer etterpå = The replacement bus comes afterwards

So if you want to mention what something happens after, you use etter + noun.

Because it refers to a specific cancellation, not just cancellation in general.

So:

• innstilling = a cancellation / cancellation as a concept
• innstillingen = the cancellation

In context, this usually means a cancellation that is already known from the situation, such as the cancelled departure that the replacement bus is responding to.

No. Innstilling can have several meanings depending on context.

Common meanings include:

• cancellation
• setting or adjustment
• sometimes attitude or recommendation, depending on the context

In this sentence, because it is about a replacement bus, the meaning is clearly cancellation. Transport context makes that interpretation natural.

The sentence has normal Norwegian main-clause word order:

• Erstatningsbussen = subject
• kommer = verb
• etter innstillingen = adverbial phrase

So it is:

• Subject + Verb + Adverbial

This is very standard.

Yes, but then Norwegian follows its verb-second rule.

You can say:

• Etter innstillingen kommer erstatningsbussen.

That is correct because the verb kommer still stays in second position.

What you cannot do is keep the subject before the verb after fronting the time phrase. So this would be wrong:

• Etter innstillingen erstatningsbussen kommer

Norwegian main clauses normally require the finite verb to be in the second position.

Because both are in the definite singular form in this sentence.

• buss → bussen
• innstilling → innstillingen

For buss, this is straightforward.

For innstilling, it is worth knowing that many nouns ending in -ing are feminine in Norwegian, but in Bokmål it is often very common to use the definite ending -en as well. So innstillingen is perfectly normal Bokmål.

A learner does not need to worry too much about that at first; the important thing is that -en here marks definiteness.
