Oppholdsadressen står i folkeregisteropplysningene.

It is a compound noun:

• opphold = stay, residence, place of stay
• adresse = address

Together, oppholdsadresse means something like residential address, address of stay, or current address depending on context.

Norwegian very often joins nouns into one word, where English might use two or more words. So oppholdsadresse is written as one unit, not split up.

In the sentence, it appears as oppholdsadressen, where -en is the definite ending, so it means the residential/current address.

Because Norwegian usually puts the definite article at the end of the noun instead of using a separate word in front.

So:

• en adresse = an address
• adressen = the address

And with the compound:

• en oppholdsadresse = a residential/current address
• oppholdsadressen = the residential/current address

So the the is built into the ending -en.

In Norwegian, stå is often used when information is written somewhere, printed somewhere, or recorded in a system.

So står here does not literally mean stands in a physical sense. It means something more like:

• is listed
• appears
• is written
• is recorded

So Oppholdsadressen står i folkeregisteropplysningene means that the address is listed in those records.

This is very natural Norwegian usage.

It is another compound noun:

• folkeregister = the population register / national registry
• opplysninger = information, details, pieces of information

So folkeregisteropplysninger means population-register information or registry details.

In the sentence it is folkeregisteropplysningene, which is the definite plural form:

• opplysning = a piece of information / a detail
• opplysninger = pieces of information / details
• opplysningene = the pieces of information / the details

So the whole word means something like the population register information/details/records.

Because Norwegian often uses opplysninger where English would simply say information.

Compare:

• Norwegian: opplysningene
• English: the information

So even though English usually treats information as an uncountable singular noun, Norwegian often uses a plural form for this idea.

That is completely normal and does not necessarily mean several separate documents. It can just mean the recorded information/details.

I usually means in.

In this sentence, it means the address is in the registry information, in the sense that it is included there or appears there.

Norwegian commonly uses i for things that are found in:

• documents
• records
• lists
• systems
• databases

So står i folkeregisteropplysningene = is listed in the registry information/records.

Yes. It is a standard Norwegian main clause:

• Oppholdsadressen = subject
• står = verb
• i folkeregisteropplysningene = prepositional phrase

So the pattern is:

Subject + verb + rest

That is the normal word order in a simple statement.

You could also move the prepositional phrase to the front for emphasis:

I folkeregisteropplysningene står oppholdsadressen.

That is also grammatical, and then the verb still stays in second position, which is a very important rule in Norwegian main clauses.

Because Norwegian normally writes compound nouns as one word.

So:

• oppholdsadresse, not oppholds adresse
• folkeregisteropplysninger, not folkeregister opplysninger

This is different from English, where similar expressions are often written as separate words, such as population register information or residential address.

For learners, this is very important: if two nouns belong together as one concept in Norwegian, they are very often written as one word.

The ending -ene is a very common definite plural ending.

For example:

• en opplysning = a detail / a piece of information
• opplysninger = details / pieces of information
• opplysningene = the details / the information

So -ene here tells you two things at once:

• plural
• definite

In other words, not just information/details in general, but the information/details.

Not always exactly.

Oppholdsadresse usually refers to the address where someone is staying or living at the moment, or the address connected to their residence in a practical/administrative sense.

Depending on context, it may overlap with:

• bostedsadresse = residential/home address
• adresse = address

But oppholdsadresse can sound a little more specific and administrative, especially in official contexts.

So a learner should notice that this is the kind of word often used in forms, public records, and government language.
