Årsaksanalysen forklarer feilen.

Norwegian very often makes compound nouns by joining words together.

Here, årsaksanalysen is built from:

• årsak = cause
• analyse = analysis
• årsaksanalyse = cause analysis / root-cause analysis
• årsaksanalysen = the cause analysis

So where English might use two or three words, Norwegian often uses one.

The -en is the definite ending for many masculine nouns in Norwegian. It corresponds to English the.

So:

• en analyse = an analysis
• analysen = the analysis

And in the compound:

• en årsaksanalyse = a cause analysis
• årsaksanalysen = the cause analysis

Unlike English, Norwegian often puts the at the end of the noun instead of using a separate word.

This is a common linking pattern in Norwegian compounds. The first noun sometimes appears in a form that connects more smoothly to the next part.

Here:

• årsak
  • analyse → årsaksanalyse

This kind of linking is something you will often just learn as part of the word. It is very common in Norwegian compound formation.

Forklarer is the present tense of å forklare = to explain.

So:

• å forklare = to explain
• forklarer = explains / is explaining

In this sentence, forklarer can naturally be understood as either:

• explains
• is explaining

depending on context.

Norwegian does not need an extra helping verb here.

English often says:

• explains
• is explaining
• does explain

But Norwegian can simply use the present tense verb:

• forklarer

So Årsaksanalysen forklarer feilen directly means The cause analysis explains the error/fault.

Feil usually means error, mistake, or fault, depending on context.

Here:

• en feil = an error / a mistake / a fault
• feilen = the error / the mistake / the fault

Again, the -en marks the definite form.

So both nouns in the sentence are definite:

• årsaksanalysen = the cause analysis
• feilen = the error

Yes. This sentence follows the basic Subject – Verb – Object pattern:

• Årsaksanalysen = subject
• forklarer = verb
• feilen = object

So it matches English structure quite closely:

• The cause analysis explains the error

That makes this sentence fairly straightforward for an English speaker.

In Norwegian, the infinitive often uses å, which is similar to English to.

So:

• å forklare = to explain

But in the sentence, the verb is not in the infinitive. It is conjugated in the present tense:

• forklarer = explains

So you use å forklare when naming the verb, but forklarer when using it in the sentence.

You usually decide from context.

Feil is a broad Norwegian word and can cover several English meanings:

• mistake when a person did something wrong
• error in technical, formal, or system-related contexts
• fault when something is defective or malfunctioning

In a sentence with årsaksanalysen, a technical reading is likely, so the error or the fault may fit best.

The letter Å/å is a separate letter in Norwegian, not just an A with a mark.

It is pronounced roughly like the vowel in British English more or law, though not exactly the same.

Very roughly:

• Årsaksanalysen ≈ OR-sahks-ah-nah-ly-sehn

That is only an approximation. The exact pronunciation will depend on accent, but the important point is that Å is its own vowel sound.

No. That would mix the indefinite article and the definite noun ending, which is not correct here.

Use one or the other:

• en årsaksanalyse = a cause analysis
• årsaksanalysen = the cause analysis

So in the sentence, årsaksanalysen already includes the, and you do not add en.

Yes, this is standard Bokmål.

Everything in the sentence is completely normal Bokmål:

• årsaksanalysen
• forklarer
• feilen

A learner can treat this as a standard modern written Norwegian sentence.
