Kilometerstanden er høy.

It means the mileage or odometer reading. In everyday use, it usually refers to how many kilometers a vehicle has been driven.

So Kilometerstanden er høy means that the vehicle has a lot of kilometers on it.

The ending -en is the Norwegian definite article for many singular nouns. Instead of putting a separate word like the in front, Norwegian often adds the definite article to the end of the noun.

• kilometerstand = mileage / odometer reading
• kilometerstanden = the mileage / the odometer reading

So kilometerstanden already includes the idea of the.

Yes. Norwegian very often combines nouns into one compound word.

Here:

• kilometer = kilometer
• stand = standing, level, reading, position

Together, kilometerstand means something like kilometer reading, which is why it is understood as mileage or odometer reading.

This kind of compound is very common in Norwegian.

Er is the present tense of å være, which means to be.

So:

• er = is / are

In this sentence, it links the subject kilometerstanden with the description høy:

• Kilometerstanden er høy = The mileage is high

Because høy agrees with the noun it describes.

Here, kilometerstanden is a singular common-gender noun, so the adjective stays in its basic form:

• Kilometerstanden er høy

Compare:

• common gender singular: Bilen er dyr
• neuter singular: Huset er dyrt
• plural: Bilene er dyre

With høy, the pattern is:

• common gender singular: høy
• neuter singular: høyt
• plural: høye

So høy is the correct form here.

Not here. In this sentence, høy is a predicative adjective: it comes after er and describes the noun.

Predicative adjectives in Norwegian agree with gender and number, but not with definiteness in the same way as adjectives placed before a noun.

So:

• Kilometerstanden er høy = correct

But when the adjective comes before the noun, definiteness matters:

• den høye kilometerstanden = the high mileage

That is why you get høy after er, but høye before a definite noun.

Høy is the natural choice here. Norwegian often uses høy for values, levels, amounts, prices, and readings.

So these sound natural:

• Kilometerstanden er høy
• Prisen er høy
• Temperaturen er høy

Using stor here would sound less natural. Stor usually means big / large, not high in the sense of a numerical value or level.

Usually, yes, but not only a car. It can refer to any vehicle that has an odometer or accumulated distance, such as:

• a car
• a motorcycle
• a van
• a truck

In most everyday situations, people will understand it as talking about a vehicle’s mileage.

Yes, absolutely. That is also a very natural sentence.

Compare:

• Kilometerstanden er høy = The mileage is high
• Bilen har høy kilometerstand = The car has high mileage

The second version is often even more common in everyday speech because it names the vehicle directly.

Because Norwegian usually marks definiteness by adding it to the noun itself.

So English:

• the mileage

Norwegian:

• kilometerstanden

This is one of the biggest structural differences English speakers notice early on.

It is the normal Norwegian statement pattern:

• Kilometerstanden = subject
• er = verb
• høy = adjective / subject complement

So the structure is:

subject + verb + description

This is very similar to English:

• The mileage is high

You would change er to var:

• Kilometerstanden var høy = The mileage was high

The adjective høy stays the same here.

Put ikke after the verb:

• Kilometerstanden er ikke høy = The mileage is not high

That placement is very typical in Norwegian main clauses:

• verb first after the subject
• ikke after the verb

A rough pronunciation guide is:

• kilometerstanden ≈ kee-LOH-meh-ter-stan-en
• er is often pronounced very lightly, sometimes almost like ær or just a weak vowel in casual speech
• høy sounds roughly like hoy, but with a Norwegian vowel quality

A more natural rhythm would be something like:

kee-LOH-meh-ter-stan-en er hoy

Exact pronunciation varies by dialect, but that rough guide will help you get started.
