Forsinkelsesbekreftelsen kommer fra togselskapet.

Because Norwegian usually puts the definite article at the end of the noun.

• bekreftelse = confirmation
• bekreftelsen = the confirmation

And:

• selskap = company
• selskapet = the company

So in this sentence:

• forsinkelsesbekreftelsen = the delay confirmation
• togselskapet = the train company / the rail company

This is very different from English, where the comes before the noun.

It is a compound noun, which is extremely common in Norwegian.

It can be broken down like this:

• forsinkelse = delay
• bekreftelse = confirmation
• -n / -en = the definite ending

So:

• forsinkelsesbekreftelse = delay confirmation
• forsinkelsesbekreftelsen = the delay confirmation

English often writes similar ideas as separate words, but Norwegian frequently joins them into one long noun.

That -s- is a linking element often used in Norwegian compounds.

So:

• forsinkelse
  • bekreftelse becomes
• forsinkelsesbekreftelse

The -s- does not usually have a separate meaning by itself here. It mainly helps connect the parts of the compound in a natural-sounding way. Native speakers just learn which compounds use it and which do not.

Kommer is the present tense of komme.

• komme = to come
• kommer = comes / is coming

In this sentence, kommer fra means comes from or originates from.

So the sentence is saying that the delay confirmation comes from the train company, meaning that the source or issuer is the train company.

Both can sometimes be possible, but they are not exactly the same.

• kommer fra = comes from / originates from
• er fra = is from

In this sentence, kommer fra emphasizes the source of the confirmation: who it is issued by or where it originates.

So Forsinkelsesbekreftelsen kommer fra togselskapet sounds natural if you mean: The delay confirmation is issued by / comes from the train company.

Fra means from.

It shows origin or source.

Examples:

• Jeg kommer fra Norge. = I come from Norway.
• Brevet kommer fra banken. = The letter comes from the bank.
• Forsinkelsesbekreftelsen kommer fra togselskapet. = The delay confirmation comes from the train company.

This is normal main clause word order in Norwegian:

subject + verb + other information

So:

• Forsinkelsesbekreftelsen = subject
• kommer = verb
• fra togselskapet = prepositional phrase

Norwegian main clauses follow the V2 rule, which means the finite verb is in the second position. Here, the subject comes first, so the verb naturally comes second.

The base form is togselskap.

Breakdown:

• tog = train
• selskap = company
• togselskap = train company / railway company
• togselskapet = the train company / the railway company

So this is another compound noun.

Also note that selskap is a neuter noun, which is why the indefinite article is et:

• et togselskap = a train company
• togselskapet = the train company

A possible indefinite version would be:

En forsinkelsesbekreftelse kommer fra et togselskap.

That means:

• en forsinkelsesbekreftelse = a delay confirmation
• et togselskap = a train company

But in real usage, the definite version is more natural if you are talking about a specific delay confirmation and a specific company.

Yes. Norwegian very often creates long nouns by combining smaller nouns into one compound.

A few similar patterns:

• billettkontor = ticket office
• reiseplan = travel plan
• togstasjon = train station
• kundeinformasjon = customer information

So even if forsinkelsesbekreftelsen looks intimidating, it follows a very normal pattern in Norwegian: build one noun by stacking related concepts together.

A natural way to process it is:

• Forsinkelsesbekreftelsen = the delay confirmation
• kommer fra = comes from / is issued by
• togselskapet = the train company

So the sentence means that the delay confirmation originates from or is provided by the train company.

A helpful learner translation might be:

The delay confirmation comes from the train company. or more naturally in some contexts: The delay confirmation is issued by the train company.
