Skademeldingen er sendt inn.

It is a compound noun:

• skade = damage / injury / claim-related damage
• melding = report / notification

Together, skademelding means a damage report or claim form/report.

Then it has the ending -en, so skademeldingen is the definite singular form: the damage report.

Because skademelding is a common-gender noun (an en-word) in Norwegian.

Its forms are:

• en skademelding = a damage report
• skademeldingen = the damage report

So the -en ending marks definiteness, similar to English the.

In Norwegian, definiteness is often shown by an ending on the noun, instead of a separate word like the.

So:

• en bil = a car
• bilen = the car

Likewise:

• en skademelding = a damage report
• skademeldingen = the damage report

This is very normal in Norwegian.

Er sendt inn is built from:

• er = present tense of å være (to be)
• sendt = past participle of å sende (to send)
• inn = the particle in

So the structure is basically be + past participle + particle.

In practice, this gives a meaning like:

• has been submitted
• is submitted
• has been sent in

In a sentence like this, English will usually translate it as has been submitted.

Yes, it is commonly understood as a passive/resultative construction.

Norwegian often uses være + past participle to describe something that is in the state of having been done:

• Døren er lukket = The door is closed
• Søknaden er sendt inn = The application has been submitted / is submitted
• Skademeldingen er sendt inn = The damage report has been submitted

If you want a more explicitly action-focused passive, Norwegian can also use:

• har blitt sendt inn
• ble sendt inn

But in everyday and administrative Norwegian, er sendt inn is very common.

Because the verb is å sende inn, a verb + particle combination.

In Norwegian, these particles are often written separately:

• å sende inn = to send in / submit
• jeg sender inn = I submit
• jeg har sendt inn = I have submitted
• skademeldingen er sendt inn = the damage report has been submitted

So inn belongs with sende, but it is still written as a separate word here.

Yes, sometimes.

You may also see:

• Skademeldingen er innsendt

That uses innsendt, which is a more fixed participial/adjectival form. It can sound a bit more formal or bureaucratic.

Both are possible, but sendt inn is very natural and common.

Because Norwegian main clauses usually follow the normal pattern:

• subject + finite verb + rest

Here:

• Skademeldingen = subject
• er = finite verb
• sendt inn = rest of the predicate

So the sentence order is exactly what you would expect in a basic statement.

An active version would name the person or group doing the action, for example:

• Vi har sendt inn skademeldingen. = We have submitted the damage report.
• Han sendte inn skademeldingen. = He submitted the damage report.
• Kunden har sendt inn skademeldingen. = The customer has submitted the damage report.

The original sentence leaves the doer unspecified, which is very common in formal or administrative language.

Not exactly.

Norwegian has another passive form made with -s:

• Skademeldingen sendes inn = The damage report is being submitted / is submitted

But your sentence uses:

• Skademeldingen er sendt inn

That usually emphasizes that the submission is completed or that the report is now in the state of having been submitted.

So both can be passive-like, but they are not used in exactly the same way.

Usually the present perfect passive:

• The damage report has been submitted.

Even though Norwegian uses er + past participle, the most natural English translation in context is often has been submitted, especially when the important point is that the action is now completed.

Sometimes English might also use:

• The damage report is submitted

but that is less common unless you mean something more general or procedural.

A few common possibilities are:

• Skademeldingen er ikke sendt inn. = The damage report has not been submitted.
• Skademeldingen er ennå ikke sendt inn. = The damage report has not yet been submitted.

So you just add ikke after er in a normal main clause.

A rough learner-friendly guide:

• skademeldingen ≈ SKAH-deh-mel-ding-en
• sendt inn ≈ sent in

A few notes:

• The sk in skade is pronounced like sh before front vowels in many Norwegian words, but in skade it is usually a plain sk sound.
• melding has a clear ng sound at the end.
• In sendt, the consonant cluster can be a little compressed in natural speech.

The exact pronunciation varies somewhat by dialect, but those rough guides will get you close.

It is fairly neutral, but it fits especially well in administrative, official, or customer-service contexts.

You might see it in:

• insurance messages
• online claim portals
• confirmation emails
• case handling systems

It does not sound strange in normal Norwegian, but it does have a slightly practical, status-update feel.
