Feiingen skjer gjennom feieluken.

Because Norwegian usually puts the definite article on the end of the noun.

• feiing = sweeping
• feiingen = the sweeping

So instead of using a separate word like the, Norwegian often adds a suffix.

The same thing happens in feieluken:

• feieluke = sweeping hatch / access hatch
• feieluken = the sweeping hatch / the access hatch

Yes. Feiing is a noun made from å feie, which means to sweep.

A very common pattern in Norwegian is:

• å feie = to sweep
• feiing = sweeping, the act of sweeping

So feiingen is the definite form of that noun: the sweeping.

If you are wondering about the spelling with double i, that is just how the noun is formed from the verb stem.

Skjer is the present tense of å skje, which means to happen, to occur, or to take place.

So literally, Feiingen skjer gjennom feieluken is something like:

• The sweeping happens through the hatch

But in natural English, depending on context, it may sound better as:

• The sweeping is done through the hatch
• The chimney is swept through the access hatch

So skjer is not always translated word-for-word as happens in English, even though that is its core meaning.

Because this kind of wording is very natural in Norwegian.

Norwegian often uses a straightforward active/event-style expression where English might prefer a passive or a more technical phrasing.

So:

• Feiingen skjer gjennom feieluken = natural Norwegian

A more formal or technical alternative could be something like:

• Feiingen utføres gjennom feieluken = The sweeping is carried out through the hatch

But skjer sounds simple and idiomatic.

Gjennom usually means through.

In this sentence, it means the sweeping is carried out through that opening or hatch.

Depending on context, English might translate it as:

• through
• via
• by way of

So gjennom is the preposition that tells you the route or opening used.

Because Norwegian normally writes compound nouns as a single word.

Here you have:

• feie = sweep
• luke = hatch, flap, small door

Together:

• feieluke = sweeping hatch / access hatch used for sweeping

Then the definite ending is added:

• feieluken = the sweeping hatch

This is very common in Norwegian. English often uses separate words, but Norwegian usually joins them.

Luke means something like hatch, flap, or small access door/opening.

In Bokmål, many nouns that are historically feminine can often take either:

• a feminine definite ending: -a
• or a common-gender/masculine-style definite ending: -en

So both of these may be seen, depending on style and dialect:

• luka
• luken

In this sentence, feieluken is perfectly normal Bokmål.

Because the sentence is talking about a specific, understood process and a specific, understood hatch.

That does not always mean a single one-time event. It can also mean something like:

• the sweeping procedure
• the access hatch used for sweeping

Norwegian often uses the definite form when the thing is already known from the situation or is being referred to as the relevant one in context.

So the sentence is not just talking about sweeping in general, but about the sweeping and the hatch involved.

Yes, but the nuance changes.

• Feiing skjer gjennom feieluken = Sweeping is done through the hatch
  This sounds more general.

• Feiingen skjer gjennom feieluken = The sweeping is done through the hatch
  This sounds more specific or context-based.

So the version with feiingen feels more anchored to a known process, situation, or instruction.

Yes. It is a very normal Norwegian declarative sentence:

• Feiingen = subject
• skjer = verb
• gjennom feieluken = prepositional phrase

So the structure is basically:

• Subject + verb + prepositional phrase

If you moved the prepositional phrase to the front, Norwegian would still keep the verb in second position:

• Gjennom feieluken skjer feiingen.

That is standard Norwegian word order.

Very often, yes.

On its own, feiing can mean sweeping in a general sense. But the word feieluke strongly suggests a technical or building-related context, especially chimney sweeping or flue maintenance.

So in real-life use, this sentence would often be understood as referring to chimney sweeping or a similar maintenance process, not just sweeping a floor.
