Røykrøret går fra ildstedet.

Røykrøret is a compound noun. Norwegian very often joins nouns together into one word.

• røyk = smoke
• rør = pipe / tube
• røykrør = smoke pipe / flue pipe
• røykrøret = the smoke pipe / the flue

So the whole word is written as one unit, not as separate words.

The ending -et marks the definite singular of a neuter noun.

Here the base noun is et rør = a pipe.
Its definite form is røret = the pipe.

In the compound, the last part decides the gender and the definite ending:

• et røykrør = a smoke pipe
• røykrøret = the smoke pipe

This is one of the biggest differences from English: Norwegian often adds the to the end of the noun instead of using a separate word.

Because Norwegian usually expresses definiteness with an ending on the noun itself.

• et ildsted = a fireplace / hearth

• ildstedet = the fireplace / the hearth

• et røykrør = a smoke pipe
• røykrøret = the smoke pipe

So in this sentence, both nouns are definite because both already include the in their endings.

Ildstedet is the definite form of ildsted, which means something like fireplace, hearth, or fireplace opening/firebox, depending on context.

Literally:

• ild = fire
• sted = place

So ildsted is literally a fire-place in the broad sense. In real usage, it can refer to the place where the fire burns in a stove or fireplace.

Right — here går does not mean walks.

The verb gå has several meanings in Norwegian. Besides walk/go, it can also mean things like:

• run / extend
• lead
• go from ... to ...
• operate in some contexts

In this sentence, går fra means something like:

• extends from
• runs from
• comes from (in a structural/physical sense)

So Røykrøret går fra ildstedet means that the smoke pipe extends from or runs from the fireplace/hearth.

Fra means from.

It marks the starting point or source:

• går fra ildstedet = goes/runs from the fireplace

So the sentence is describing where the pipe begins.

Not in the same way.

• fra = from
• til = to

This sentence focuses on the starting point of the smoke pipe, so fra is the natural choice.

If you used til, you would be talking about where something goes to, not where it starts.

Yes. This is standard word order:

• Røykrøret = subject
• går = verb
• fra ildstedet = prepositional phrase

So the pattern is basically:

Subject + verb + prepositional phrase

That is a very normal sentence structure in Norwegian.

Går is the present tense of gå.

• å gå = to go
• går = goes / is going / runs / extends

In Norwegian, the present tense is often used for general facts, descriptions, and things that are normally true. Here it describes how the smoke pipe is arranged.

The indefinite version would be:

Et røykrør går fra et ildsted.

That means A smoke pipe goes from a fireplace/hearth.

Compare:

• Et røykrør = a smoke pipe

• Røykrøret = the smoke pipe

• Et ildsted = a fireplace/hearth
• Ildstedet = the fireplace/hearth

In Norwegian compounds, the last part usually determines the gender.

Here the last part is rør, which is neuter:

• et rør

So the whole compound is also neuter:

• et røykrør
• røykrøret

This is a very useful rule for learners.

It is closer to runs from or extends from.

For physical objects like pipes, cables, roads, or lines, Norwegian often uses gå where English might prefer:

• run
• extend
• lead

So in context, Røykrøret går fra ildstedet is best understood structurally, not as movement. The pipe is not moving; the sentence is describing its physical layout.
