Sporet passer til sjangeren.

Because sporet is the definite singular form of et spor.

• et spor = a track / a trace
• sporet = the track / the trace

In Norwegian, the definite article is usually added as an ending, instead of being a separate word like the in English.

So:

• spor is not normally used by itself as a singular noun
• the full singular forms are et spor and sporet

Because sjangeren is the definite singular form of en sjanger.

• en sjanger = a genre
• sjangeren = the genre

This is the same general pattern as many Norwegian nouns:

• en bil → bilen
• en sang → sangen
• en sjanger → sjangeren

So the sentence uses definite nouns on both sides:

• sporet = the track
• sjangeren = the genre

Because Norwegian usually puts definiteness on the noun itself.

Instead of saying:

• the track
• the genre

Norwegian says:

• sporet
• sjangeren

That means the idea of the is built into the noun ending.

This is very common in Norwegian, so English speakers often need time to get used to not seeing a separate article.

Here, passer til means something like:

• fits
• suits
• matches
• is appropriate for

So passer til is a very common expression for saying that one thing goes well with another.

Examples:

• Det passer til temaet. = It fits the theme.
• Fargen passer til rommet. = The color suits the room.
• Sangen passer til filmen. = The song fits the film.

In your sentence, the idea is that the track is suitable for or consistent with the genre.

Because Norwegian often uses passe til when talking about something fitting or matching something else.

Here, til is part of the natural expression:

• passe til noe = to fit / suit / go with something

English speakers often want to translate word-for-word, but it is better to learn passer til as a chunk.

Compare:

• Det passer til sjangeren. = It fits the genre.
• Denne jakken passer til skoene. = This jacket goes with the shoes.

So til is not optional here in this meaning.

Yes. Passer is the present tense form of å passe.

• å passe = the infinitive
• passer = present tense

So:

• Sporet passer til sjangeren. = The track fits the genre.

This is a very regular pattern in Bokmål:

• å snakke → snakker
• å like → liker
• å passe → passer

The word order is the normal Norwegian pattern:

Subject + verb + prepositional phrase

So here:

• Sporet = subject
• passer = verb
• til sjangeren = prepositional phrase

That gives:

• Sporet passer til sjangeren.

This is very similar to standard English word order, which makes the sentence fairly straightforward.

Because it comes before the finite verb passer in a normal main clause, and it is the thing doing the “fitting.”

So in:

• Sporet passer til sjangeren.

the structure is:

• Sporet = the thing being described
• passer = the action/state
• til sjangeren = what it fits

If you changed the sentence to a question, you would see the verb move:

• Passer sporet til sjangeren? = Does the track fit the genre?

That makes the subject role even clearer.

Yes. Spor can have several meanings depending on context, for example:

• track
• trace
• trail
• sometimes audio track or music track, depending on context

So the exact English word can change, but the Norwegian grammar stays the same:

• et spor
• sporet

This is normal in Norwegian: one noun can cover several related meanings that English separates more clearly.

It is a loanword, ultimately related to French genre, but in Norwegian it behaves like a normal noun:

• en sjanger
• sjangeren
• sjangre = genres
• sjangrene = the genres

So even though it may look familiar to an English speaker, you still need to learn its Norwegian article and endings.

In standard Norwegian, sj is usually pronounced like the sh sound in English ship.

So sjanger starts with a sound close to:

• shahng-

Not exactly English, but close enough as a starting point.

A rough learner-friendly approximation of sjangeren would be:

• SHAHNG-er-en

The exact pronunciation varies a bit by dialect, but sj ≈ English sh is a good practical rule.

Usually, for this meaning, Sporet passer til sjangeren is the natural choice.

With passe, Norwegian can sometimes use different patterns depending on meaning, but when you mean that something fits or goes with a category, style, or context, passe til is the safe and idiomatic expression.

So for a learner, it is best to remember:

• passe til noe = fit / suit / go with something

The main things are:

1. Definite endings

   • sporet
   • sjangeren

2. The verb phrase passer til

   • learn it as one expression

3. No separate word for the

   • definiteness is built into the noun

4. Normal Norwegian main-clause word order

   • subject + verb + rest

So even though the sentence is short, it shows several important features of Norwegian grammar very clearly.
