C/o-adressen brukes til post.

c/o-adressen means the care-of address.

It refers to an address used when mail is sent to someone at another person’s address. For example, if you live temporarily with a friend, your mail might be sent to your name c/o your friend at that address.

In Norwegian, this is written as one compound with a hyphen: c/o-adressen.

The hyphen is used because c/o is an abbreviation and it is being attached to the noun adressen.

Norwegian often uses a hyphen in compounds when:

• the first part is an abbreviation
• the first part is a symbol or special form
• it makes the word easier to read

So:

• c/o-adressen = the c/o address

Because adressen is the definite singular form of adresse.

The forms are:

• en adresse = an address
• adressen = the address

So c/o-adressen means the c/o address, not just a c/o address.

brukes means is used.

It comes from the verb å bruke = to use.

So:

• å bruke = to use
• brukes = is used / gets used

In this sentence, it is a passive form:

• C/o-adressen brukes til post.
• The c/o address is used for mail.

Yes. This is the -s passive, which is common in Norwegian.

Compare:

• Vi bruker adressen. = We use the address.
• Adressen brukes. = The address is used.

So in the sentence:

• C/o-adressen brukes til post. the focus is on what the address is used for, not on who uses it.

Yes, sometimes.

• brukes = a short passive form
• blir brukt = another passive form, often a bit more explicit

In many cases both are possible:

• C/o-adressen brukes til post.
• C/o-adressen blir brukt til post.

The -s passive often sounds more neutral and concise, which fits well here.

til post means for mail or for postal purposes.

Here post means mail, not necessarily the post office.

So the sentence means that the care-of address is used for receiving or handling mail.

A more expanded version could be:

• C/o-adressen brukes til å motta post.
• The c/o address is used to receive mail.

In Norwegian, til is often used after brukes to show purpose.

A very common pattern is:

• brukes til + noun
• brukes til + infinitive phrase

Examples:

• Denne kniven brukes til brød. = This knife is used for bread.
• Denne kniven brukes til å skjære brød. = This knife is used for cutting bread.

So:

• brukes til post = is used for mail

Even though English often uses for, Norwegian commonly uses til in this structure.

Yes, it is completely normal.

The structure is:

• C/o-adressen = subject
• brukes = verb
• til post = prepositional phrase showing purpose

So it follows a basic Norwegian sentence pattern:

• subject + verb + other information

Very straightforward and standard.

In practice, many Norwegians say the letters, roughly like se-o.

Because it is an imported abbreviation, pronunciation can vary a little depending on context and speaker. In writing, though, c/o is very common and easily understood.

The important thing for a learner is mainly to recognize that c/o refers to a care-of address.

Yes. That version is a bit more explicit.

Compare:

• C/o-adressen brukes til post. = The c/o address is used for mail.
• C/o-adressen brukes til å motta post. = The c/o address is used to receive mail.

The second version spells out the purpose more clearly. The original sentence is shorter and more compact.

Yes, this is standard Bokmål.

Everything in the sentence is normal Bokmål:

• adressen
• brukes
• til post

A learner can treat it as standard written Norwegian.
