Tyveriet er meldt.

Tyveriet is the definite singular form of tyveri, which means theft.

• et tyveri = a theft
• tyveriet = the theft

Tyveri is a neuter noun, which is why the indefinite article is et and the definite ending is -et.

In Norwegian, the definite article is usually attached to the end of the noun.

So instead of saying something like the theft with a separate word, Norwegian says:

• tyveriet = the theft

This is very normal in Norwegian:

• en bil = a car
• bilen = the car
• et hus = a house
• huset = the house

Meldt is the past participle of the verb melde, which often means to report, to notify, or to register, depending on context.

In this sentence, meldt means reported.

So:

• melde = to report
• meldt = reported

Because er meldt is a passive/resultative construction. It focuses on the fact that the theft has been reported, not on who reported it.

Compare:

• Noen har meldt tyveriet.
  = Someone has reported the theft.
  This is active and mentions an implied doer.

• Tyveriet er meldt.
  = The theft has been reported.
  This is passive-like and focuses on the theft itself.

A native English speaker often expects has been reported, and this Norwegian structure is one common way to express that idea.

It can correspond to both in English, but in most real contexts the most natural translation is:

The theft has been reported.

The Norwegian sentence often emphasizes the resulting state: the reporting has already happened, and now the theft stands as reported.

So in English:

• literal-looking: The theft is reported
• more natural in most contexts: The theft has been reported

Yes. The sentence does not say who reported the theft.

That is very common in Norwegian passive-style expressions. The person or institution that did the reporting is either:

• unknown,
• unimportant,
• or already understood from context.

If you wanted to mention the person, you would use a different structure, for example:

• Eieren har meldt tyveriet.
  = The owner has reported the theft.

Er meldt usually describes a state/result: the theft is now in the status of having been reported.

Blir meldt would usually describe the action as happening, or something that happens generally.

Compare:

• Tyveriet er meldt.
  = The theft has been reported / is reported.
• Tyveriet blir meldt.
  = The theft is being reported or gets reported

So er meldt is the natural choice when you mean the report has already been made.

Ble meldt focuses more directly on the event in the past:

• Tyveriet ble meldt i går.
  = The theft was reported yesterday.

Er meldt focuses more on the current result/state:

• Tyveriet er meldt.
  = The theft has been reported.

A simple way to remember it:

• ble meldt = the reporting happened
• er meldt = the theft now stands as reported

Not exactly.

• melde is a broader word: report, notify, register
• anmelde is more specific and often means report to the police or formally report

So:

• Tyveriet er meldt.
  can mean The theft has been reported
• Tyveriet er anmeldt.
  more specifically suggests The theft has been reported to the police

In real life, context often makes the meaning clear.

Yes. You can add that with til.

For example:

• Tyveriet er meldt til politiet.
  = The theft has been reported to the police.
• Tyveriet er meldt til forsikringsselskapet.
  = The theft has been reported to the insurance company.

So til is often the preposition you need when you say where or to whom something was reported.

Yes. It sounds concise, natural, and slightly formal or matter-of-fact. You could easily see this kind of wording in:

• police-related contexts
• insurance contexts
• news reports
• official communication

It is the kind of short sentence Norwegian often uses when the important information is simply the status: the theft has already been reported.

Not in the way a beginner might first think. Meldt is simply the normal past participle form of melde.

So you should learn it as:

• melde → meldt

In other words, meldt is the verb form you need here; it is not just created on the spot by taking melde and adding a neuter ending because the noun is tyveriet.
