Flyttemeldingen er sendt.

It is a compound noun:

• flytte = to move
• melding = message, notice, notification

So flyttemelding is literally something like moving notification. In real use, it usually means an official notice that you have moved, often similar to a change-of-address notification.

The ending -en makes it definite, so flyttemeldingen means the moving notification / the change-of-address notification.

Because Norwegian normally writes compound nouns as one single word.

So English might use several words, but Norwegian often combines them:

• flytte
  • melding → flyttemelding
• flyttemelding
  • definite ending -en → flyttemeldingen

This is very common in Norwegian. English speakers often want to separate these words, but in Norwegian that would usually be wrong.

Yes. In Norwegian, the definite article is often attached to the end of the noun instead of being a separate word.

Compare:

• en flyttemelding = a moving notification
• flyttemeldingen = the moving notification

So -en here is doing the job that the does in English.

Yes, in Bokmål that is possible.

The noun melding can be treated as:

• masculine: en melding – meldingen
• feminine: ei melding – meldinga

So both of these are possible:

• flyttemeldingen
• flyttemeldinga

Both are understandable and correct in Bokmål. -en is often more neutral/common in formal written Bokmål, while -a can sound more colloquial or more clearly feminine.

Er sendt is er + a past participle.

• er = present tense of å være = to be
• sendt = past participle of å sende = to send

Together, er sendt means that the notification is in the state of having been sent. In natural English, that is often best translated as has been sent.

So although it looks literally like is sent, the real meaning in context is usually has been sent.

Because the sentence is focusing on the notification, not on the person who sent it.

• Flyttemeldingen er sendt. = The notification has been sent.
• Jeg har sendt flyttemeldingen. = I have sent the notification.

With har sendt, you normally need someone as the subject, such as I, she, they, and so on.
With er sendt, the focus is on the thing itself and its status.

These are different ways of talking about the action:

• er sendt = has been sent / is sent
  This usually emphasizes the completed result or current status.

• blir sendt = is being sent / gets sent
  This focuses more on the process or a general passive meaning.

• ble sendt = was sent
  This is simple past.

So in this sentence, er sendt tells you that the sending is already completed.

Sendt is the past participle of å sende.

A few useful forms are:

• å sende = to send
• sender = sends / is sending
• sendte = sent
• sendt = sent

You will see sendt in structures like:

• Jeg har sendt den. = I have sent it.
• Den er sendt. = It has been sent.

It is normal Norwegian main-clause word order:

• Flyttemeldingen = subject
• er = finite verb
• sendt = past participle

So the pattern is basically:

Subject + verb + participle

Norwegian main clauses follow the verb-second rule, so if you move something else to the front, the verb still stays in second position:

• Nå er flyttemeldingen sendt. = Now the notification has been sent.

Yes, it sounds fairly neutral and administrative.

The word flyttemelding is especially common in official contexts, such as registering a move with the authorities. So Flyttemeldingen er sendt sounds very natural in a form, website, email confirmation, or official message.

In casual speech, people might also say things like:

• Jeg har sendt inn flyttemelding.
• Nå har jeg meldt flytting.

But the original sentence is completely natural.

A rough pronunciation guide for an English speaker is:

FLYT-te-mel-di-ngen er sent

A few helpful notes:

• flytt- has the Norwegian y sound, which is not the same as English y. It is closer to the u in French tu or German ü.
• The stress is mainly on the first part: FLYT-te-meldingen
• In sendt, the d is often weak or not clearly heard in normal speech.

You do not need perfect pronunciation to be understood, but the vowel in flytt- is the trickiest part for most English speakers.
