Medeieren leverer vognkortet.

Because medeieren is the definite singular form of medeier (co-owner).

In Norwegian, instead of usually putting a separate word like the in front of the noun, you often add the definite ending to the noun itself:

• en medeier = a co-owner
• medeieren = the co-owner

So -en here works like English the.

Medeier means co-owner or joint owner.

It is made up of:

• med- = co-, with
• eier = owner

So medeier is someone who owns something together with someone else.

Vognkortet is a compound noun plus a definite ending.

It breaks down like this:

• vogn = vehicle/wagon
• kort = card/document
• vognkort = a vehicle document / registration paper
• vognkortet = the vehicle registration document

The -et ending shows that the noun is definite singular for a neuter noun.

So:

• et vognkort = a vehicle registration document
• vognkortet = the vehicle registration document

You know from its indefinite article:

• et vognkort = neuter
• therefore the definite singular becomes vognkortet

In Norwegian, gender affects the article and the definite ending:

• masculine: en bil → bilen
• feminine: ei bok → boka/boken
• neuter: et hus → huset

So et vognkort → vognkortet follows the normal neuter pattern.

Leverer is the present tense of the verb å levere.

Examples:

• å levere = to deliver / hand in
• leverer = delivers / is delivering
• leverte = delivered
• har levert = has delivered

In this sentence, leverer means delivers or sometimes is handing in, depending on context.

Because Norwegian usually marks definiteness by adding an ending to the noun.

So instead of saying something like the co-owner with a separate article, Norwegian often says:

• medeieren

And instead of the registration document, it says:

• vognkortet

This is one of the biggest differences from English. The the idea is built into the noun ending.

Yes. This is standard Norwegian main-clause word order:

Subject + verb + object

• Medeieren = subject
• leverer = verb
• vognkortet = object

So it works just like basic English word order:

• The co-owner delivers the registration document

Usually, no—not in a neutral sentence like this.

Medeieren by itself already means the co-owner. Adding den would usually only happen in special structures, such as when there is an adjective:

• den nye medeieren = the new co-owner

Without an adjective, den medeieren often sounds marked, contrastive, or unusual, like that co-owner or that particular co-owner depending on context.

So the natural version here is simply:

• Medeieren leverer vognkortet

It is usually pronounced roughly like leh-VEH-rer in Bokmål-based standard speech.

A few helpful points for an English speaker:

• the r sounds are Norwegian r sounds, not English r
• the stress is on the second syllable: le-VE-rer
• the final -er is pronounced, not silent

Pronunciation varies by dialect, but the spelling-to-sound relationship here is fairly regular.

This sentence is standard Bokmål.

A Nynorsk version could look different, for example:

• Medeigaren leverer vognkortet

The main difference here is medeieren in Bokmål versus medeigaren in Nynorsk.

Yes. Å levere is quite flexible in Norwegian.

Depending on context, it can mean:

• deliver
• hand in
• submit
• sometimes even provide

In this sentence, with vognkortet, it most naturally suggests handing over or submitting the vehicle registration document.

A natural indefinite version would be:

• En medeier leverer et vognkort.

That means:

• A co-owner delivers a vehicle registration document.

Compare:

• Medeieren leverer vognkortet. = The co-owner delivers the vehicle registration document.
• En medeier leverer et vognkort. = A co-owner delivers a vehicle registration document.

This contrast is useful because it shows both Norwegian articles and definite endings clearly.
