I den forbindelse leser bostyreren proklamaet.

I den forbindelse is a fixed expression meaning in that connection, in that regard, or in this context.

Literally:

• i = in
• den = that
• forbindelse = connection

So it introduces the sentence by linking it to something mentioned earlier. This kind of fronted phrase is very common in Norwegian formal writing.

This is because Norwegian follows the V2 rule in main clauses: the finite verb usually comes in second position.

Here, the first element is:

• I den forbindelse

So the verb must come next:

• leser

And then the subject follows:

• bostyreren

So the structure is:

• I den forbindelse
  • leser
    • bostyreren
      • proklamaet

If you put the subject first, you would get:

• Bostyreren leser proklamaet i den forbindelse.

That is also grammatical, but it has a slightly different emphasis.

Bostyreren is the definite form of bostyrer.

Breakdown:

• bo = estate, bankruptcy estate, or deceased person's estate, depending on context
• styrer = manager/administrator

So bostyrer means something like:

• estate administrator
• trustee
• receiver

And bostyreren means:

• the estate administrator / the trustee

The exact English translation depends on the legal context.

Because it is a definite singular noun.

For many common-gender Norwegian nouns:

• indefinite: en bostyrer = an estate administrator
• definite: bostyreren = the estate administrator

So the ending -en works like English the attached to the noun.

Because proklama is a neuter noun: et proklama.

For neuter nouns, the definite singular usually ends in -et:

• et hus → huset
• et brev → brevet
• et proklama → proklamaet

So:

• proklama = a proclamation/public notice
• proklamaet = the proclamation/public notice

In Norwegian, the definite article is often attached to the end of the noun instead of standing separately in front.

So English:

• the proclamation

becomes Norwegian:

• proklamaet

You do not normally say a separate word for the here. The definiteness is already built into the noun ending -et.

Leser is the present tense of å lese.

So:

• å lese = to read
• leser = reads / is reading

In Norwegian, the present tense often covers both English meanings:

• reads
• is reading

So the sentence could describe either a general present action or something happening now, depending on context.

Yes, it sounds somewhat formal and is especially common in:

• official writing
• legal language
• administrative texts
• news reports

In everyday speech, people might more often say things like:

• i den sammenhengen
• da
• i forbindelse med det

But I den forbindelse is perfectly normal and natural in formal Norwegian.

Yes, but the meaning shifts slightly.

• I den forbindelse = in that connection
  Refers back to something already mentioned.

• I denne forbindelse = in this connection
  Points more directly to the matter currently being discussed.

Both are possible, but den often feels more like a backward reference, while denne feels more immediate or pointed.

Yes. It is a very typical example of Norwegian main-clause word order:

1. something placed first for context or emphasis
2. the finite verb in second position
3. the subject
4. the rest of the sentence

So here:

1. I den forbindelse
2. leser
3. bostyreren
4. proklamaet

This is one of the most important patterns for learners to get comfortable with in Norwegian.
