Stemmeflertallet kreves.

It is a compound noun:

• stemme = vote
• flertall = majority

So stemmeflertall means a majority of votes or vote majority.
With the ending -et, stemmeflertallet means the majority of votes.

The ending -et marks the definite form of a neuter noun in Norwegian.

• et stemmeflertall = a majority of votes
• stemmeflertallet = the majority of votes

This is different from English, which usually adds a separate word like the. In Norwegian, the definiteness is often added to the end of the noun.

It is singular.

Even though it refers to many votes, the noun flertall itself is a singular noun meaning majority. So the whole word is treated as one thing:

• et flertall = a majority
• flertallet = the majority

That is why the verb is singular too.

Kreves is the present passive form of kreve, which means to require.

So:

• kreve = to require
• kreves = is required / are required

In this sentence, kreves is best understood as is required.

Norwegian often uses the -s passive for general rules, formal statements, and written style.

• kreves = is required / is being required
• er krevd = is required in a more result-focused or descriptive sense

In formal language, especially in rules or procedures, kreves sounds very natural.

So Stemmeflertallet kreves has the feel of a formal rule or requirement.

Because Norwegian usually puts the definite marker on the noun itself.

So instead of:

• the majority

Norwegian often says:

• flertallet

The the idea is built into the ending.

Yes, it is grammatically normal: subject + verb.

• Stemmeflertallet = subject
• kreves = verb

So the structure is straightforward. However, in real Norwegian, a sentence like this may sound somewhat formal or marked depending on context. You may also see more natural alternatives such as:

• Det kreves stemmeflertall. = A majority of votes is required.

That version is often more idiomatic when stating a general rule.

Yes, and that changes the nuance.

• Stemmeflertallet kreves = the majority of votes is required
• Stemmeflertall kreves = a majority of votes is required

The version without -et is more general and often sounds more natural when stating a requirement.

The version with -et points to a specific majority, or treats it as something already known from context.

Yes. Norwegian very often forms new nouns by combining existing words into one compound.

For example:

• stemme
  • rett = stemmerett = right to vote
• valg
  • resultat = valgresultat = election result
• stemme
  • flertall = stemmeflertall = majority of votes

This is very common and important in Norwegian vocabulary building.

Because Norwegian usually expresses this idea with a compound noun, not with a separate plural noun plus another noun.

So instead of something like votes majority, Norwegian combines the idea into one word:

• stemmeflertall

This is the normal Norwegian way to express it.

No. Flertall can mean majority in several contexts:

• a majority of votes
• a majority of people
• a parliamentary majority

In stemmeflertall, it specifically refers to a majority in voting.

Usually it sounds more formal, administrative, or legal than conversational.

You might find this kind of wording in:

• rules
• statutes
• meeting procedures
• official documents

In everyday speech, Norwegians might phrase the same idea more naturally in a fuller sentence. For example:

• Det kreves stemmeflertall.
• Man må ha stemmeflertall.

The given sentence is short and formal.
