Bruddgebyret er høyt.

It is a compound noun:

• brudd = break, breach, cancellation, termination, etc. depending on context
• gebyr = fee
• -et = the definite ending for a singular neuter noun

So bruddgebyret is literally the break/breach/cancellation fee. In Norwegian, the last part of a compound usually tells you what kind of thing it is. Here, it is a type of gebyr.

Because Norwegian normally writes compound nouns as a single word.

English often uses two words, such as cancellation fee, but Norwegian usually combines them:

• bruddgebyr = cancellation fee / breach fee

Writing brudd gebyr would look wrong in standard Norwegian.

Because gebyr is a neuter noun.

Its basic forms are:

• et gebyr = a fee
• gebyret = the fee

The same pattern applies to the compound:

• et bruddgebyr = a cancellation/breach fee
• bruddgebyret = the cancellation/breach fee

So -et is doing the job that the does in English.

In Norwegian, definiteness is often added to the end of the noun instead of using a separate word.

So:

• bruddgebyret = the cancellation fee

That means you do not need a separate article here. The ending -et already includes the meaning of the.

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

So:

• er = is / are / am, depending on the subject in English

In this sentence, Bruddgebyret er høyt, it means is.

Because the adjective must agree with the noun in gender and number, even when it comes after er.

The adjective høy changes like this:

• høy = common gender singular
• høyt = neuter singular
• høye = plural and some definite uses

Since bruddgebyret is a singular neuter noun, the correct form is høyt.

Compare:

• Avgiften er høy = The fee is high.
  (avgift is common gender)
• Gebyret er høyt = The fee is high.
  (gebyr is neuter)
• Gebyrene er høye = The fees are high.
  (plural)

Because høyt is a predicative adjective here, meaning it comes after er and describes the subject.

In Norwegian, predicative adjectives do not take the definite -e form just because the noun is definite.

So:

• bruddgebyret er høyt = correct
• bruddgebyret er høye = not correct here

But if the adjective comes before a definite noun, then you do use the definite form:

• det høye bruddgebyret = the high cancellation fee

Yes. This is the standard word order for a simple main clause:

• Bruddgebyret = subject
• er = verb
• høyt = complement/adjective

So the pattern is:

• Subject + verb + adjective

This is completely natural Norwegian.

You would say:

• et høyt bruddgebyr

Here:

• et = a
• høyt = high, neuter singular form
• bruddgebyr = cancellation/breach fee

So the sentence could also be rephrased as:

• Det er et høyt bruddgebyr = It is a high cancellation fee / There is a high cancellation fee

No. Brudd is a broad word, and its exact meaning depends on context.

It can refer to things like:

• a break
• a breach
• a breakup
• a fracture
• a cancellation
• a termination of a contract or agreement

So in bruddgebyr, the meaning depends on the situation. It might be a fee for breaking a contract, canceling early, or violating an agreement.

You might hear dyrt in some contexts, but høyt is usually more natural for fees, prices, rates, taxes, and similar amounts.

So:

• Bruddgebyret er høyt = very natural
• Bruddgebyret er dyrt = less idiomatic in this exact sense

A good rule is:

• use høy / høyt for amounts and charges
• use dyr / dyrt for something being expensive in general

A rough learner-friendly guide would be:

• BRUDD-ge-BYR-et er høyt

A few pronunciation notes:

• gebyr has stress on the last syllable
• the y sound in gebyr is like German ü or French u
• the vowel in høyt is a rounded sound somewhat like English oy, but not exactly the same

If you do not have the exact Norwegian vowels yet, an approximate pronunciation is fine at first. The most important thing is to keep høyt distinct from høy.
