Kursen går nordover.

Because Norwegian usually adds the definite article to the end of the noun instead of putting it in front.

So:

• kurs = course / heading
• kursen = the course / the heading

In this sentence, -en is the definite ending.

Here, kurs is being used with the definite ending -en, so kursen means the course / the heading.

A learner may notice that Norwegian nouns can vary by gender and sometimes by meaning or usage, but in this sentence the form you need is simply kursen. The important point is that the noun is definite.

Probably not. Kurs can mean a class, training course, or course of study, but it can also mean a course, heading, or direction.

Because the sentence says går nordover, the natural meaning here is about direction/heading, not a school class. So the context tells you which meaning is intended.

Gå often means more than just walk. In Norwegian, it can also mean:

• go
• run
• proceed
• head

So in a sentence like Kursen går nordover, går means something like goes/heads/runs northward, not that something is literally walking.

No. Norwegian verbs do not change for person or number in the present tense.

So you get:

• jeg går
• du går
• han går
• vi går

The verb form stays går every time. That is much simpler than English.

Nordover is an adverb of direction. It means northward or northwards.

It tells you the direction something is moving, pointing, or extending in.

You will see the same pattern in words like:

• sørover = southward
• østover = eastward
• vestover = westward

Because nordover specifically expresses movement or direction toward the north.

• nord = north
• nordover = northward / heading north

So Kursen går nordover sounds natural because it describes direction. Saying Kursen går nord would sound much less natural in standard Norwegian.

Yes, that is possible.

• nordover = northward
• mot nord = toward the north

The difference is small. Nordover is a compact, very natural directional adverb. Mot nord is also correct, but it feels a little more like in the direction of north.

It is present tense.

Norwegian often uses the simple present where English might use either:

• goes north
• is going north
• is heading north

So even though English may prefer a progressive form in some contexts, Norwegian can simply use går.

Because this is the normal word order for a main clause in Norwegian:

• Kursen = subject
• går = finite verb
• nordover = adverbial of direction

So the basic pattern is:

subject + verb + other information

You can move another element to the front for emphasis, but then Norwegian still keeps the verb in second position. For example:

Nordover går kursen.

That is possible, but it is more marked than the neutral Kursen går nordover.
