Prisen er ekstremt høy.

In Norwegian, the definite article is often attached to the end of the noun.

• pris = price
• prisen = the price

So -en is the definite ending for many masculine nouns in Bokmål. Instead of using a separate word like English the, Norwegian often adds the ending directly to the noun.

Er is the present tense of å være (to be).

So:

• jeg er = I am
• du er = you are
• prisen er = the price is

Norwegian does not change the present-tense form depending on the subject the way English does. It is just er for all persons.

Here, ekstremt is being used as an adverb, meaning extremely.

The base adjective is ekstrem = extreme, but when adjectives are used adverbially in Norwegian, they often take -t:

• ekstrem = extreme
• ekstremt = extremely

So in Prisen er ekstremt høy, ekstremt modifies høy, not prisen.

Because høy agrees with prisen, which is a singular noun of common gender.

When an adjective is used after er and describes a singular common-gender noun, the basic form is used:

• en høy pris = a high price
• Prisen er høy = The price is high

You would use høyt with a neuter singular noun:

• et høyt nivå = a high level
• Nivået er høyt = The level is high

So prisen takes høy, not høyt.

Yes. Norwegian commonly says that a price is high:

• Prisen er høy = The price is high

This matches English quite closely.

But learners should also know the difference between høy pris and dyr:

• Prisen er høy = The price is high
• Den er dyr = It is expensive

These are similar in meaning, but not always identical in focus. Høy pris talks about the price itself; dyr describes the thing as expensive.

Yes. Both are natural, but the strength is different:

• veldig høy = very high
• ekstremt høy = extremely high

Ekstremt is stronger and more emphatic. In everyday speech, veldig is probably more common.

The basic order here is:

subject + verb + adverb + adjective

• Prisen = subject
• er = verb
• ekstremt = adverb
• høy = adjective

So:

• Prisen er ekstremt høy.

This is standard Norwegian word order in a simple statement.

Yes, but Norwegian follows the verb-second rule in main clauses. That means the finite verb usually stays in the second position.

For example:

• Prisen er ekstremt høy.
• I dag er prisen ekstremt høy.

In the second sentence, I dag comes first, so er still stays in second position, before prisen.

Høy can be tricky for English speakers because of the vowel sound.

A rough guide:

• h is pronounced normally
• øy is a diphthong that does not exist exactly in English

It sounds somewhat like starting with a rounded vowel and gliding forward. Listening to native audio is the best way to learn it accurately.

Also note:

• høy = high
• høyt = neuter/basic adverb-related form in some contexts

The spelling ø is important; it is not the same as o.

In Bokmål, pris is normally treated as a masculine noun:

• en pris
• prisen

In many Norwegian contexts, masculine and feminine nouns can both behave as common gender, but pris is not normally feminine. So learners should stick with en pris and prisen.

Yes, depending on context, that can work.

Pris usually means price, but in some situations English might prefer cost. However, the most direct and usual translation is still:

• The price is extremely high

If you are talking about how much something is being sold for, price is usually the best match.
