Vibrasjonen stopper.

In Norwegian, the definite article is usually attached to the end of the noun.

So:

• en vibrasjon = a vibration
• vibrasjonen = the vibration

That -en ending is doing the job that the does in English.

The basic form is en vibrasjon.

Useful forms are:

• en vibrasjon = a vibration
• vibrasjonen = the vibration
• vibrasjoner = vibrations
• vibrasjonene = the vibrations

So if you look this word up in a dictionary, you would normally search for vibrasjon.

Stopper is the present tense of å stoppe.

So:

• å stoppe = to stop
• stopper = stop / stops / is stopping
• stoppet = stopped

In this sentence, Vibrasjonen stopper, the verb is in the present tense.

It can mean either, depending on context.

Norwegian present tense often covers both:

• The vibration stops
• The vibration is stopping

If you want to make it clearer that the stopping is already completed, Norwegian often uses:

• Vibrasjonen har stoppet = The vibration has stopped

So stopper is present, while har stoppet makes the completed result clearer.

Yes. In a normal statement, Norwegian usually puts the subject first and the verb second:

• Vibrasjonen stopper.

That is the standard declarative order.

If you turn it into a yes/no question, the verb comes first:

• Stopper vibrasjonen? = Is the vibration stopping? / Does the vibration stop?

And if another element comes first, Norwegian still usually keeps the finite verb in second position:

• Nå stopper vibrasjonen. = Now the vibration stops / is stopping.

Yes.

In Vibrasjonen stopper, it is used intransitively: the vibration itself stops.

But stoppe can also be transitive, meaning something stops something else:

• Jeg stopper bilen. = I stop the car.
• Han stopper maskinen. = He stops the machine.

So this verb is flexible, much like stop in English.

Sometimes, yes.

A close alternative is stanser:

• Vibrasjonen stanser.

This also means The vibration stops and can sound a bit more formal or technical in some contexts.

Slutter is less natural here in many situations. Slutte often means quit, finish, or end, and it does not fit physical processes as neatly as stoppe does.

So for this sentence, stopper is a very natural choice.

A rough pronunciation guide is:

• vibrasjonen ≈ vih-brah-shoo-nen
• stopper ≈ STOP-per

A few helpful notes:

• The -sjon part is pronounced like shoon.
• The o in stopper is short.
• The double pp helps show that the vowel before it is short.

Pronunciation varies by dialect, but this rough guide will get you close.

Yes. Because the noun is definite, it usually refers to a vibration that is already known from the context.

So vibrasjonen suggests:

• the vibration
• a specific vibration that speaker and listener can identify

If you wanted a vibration, you would use en vibrasjon instead.

Yes, the verb would often be written differently.

In Nynorsk, you would commonly see:

• Vibrasjonen stoppar.

The main difference here is:

• Bokmål: stopper
• Nynorsk: stoppar

The noun vibrasjonen can stay the same.
