Tilgangsrettigheten er fjernet.

It is a compound noun:

• tilgang = access
• rettighet = right, entitlement, permission

So tilgangsrettighet means something like access right or access permission.

With the ending -en, tilgangsrettigheten means the access right / the access permission.

Because Norwegian usually writes compound nouns as one word.

So where English might write:

• access right
• user account
• school building

Norwegian often combines them:

• tilgangsrettighet
• brukerkonto
• skolebygning

This is very normal in Norwegian, even when the word gets long.

That -s- is a linking sound, often called a binding -s or fuge-s.

So the word is built like this:

• tilgang
• -s-
• rettighet

The -s- does not mean possession here. It is just a common way to connect parts of a compound noun in Norwegian.

Many compounds have this linking -s-, but not all of them. Unfortunately, it often just has to be learned word by word.

In Norwegian, the is often added to the end of the noun instead of being a separate word.

So:

• en tilgangsrettighet = an access right
• tilgangsrettigheten = the access right

That final -en is the definite ending.

It is singular.

• tilgangsrettighet = access right / permission
• tilgangsrettigheten = the access right / permission

If it were plural, you would normally get:

• tilgangsrettigheter = access rights / permissions
• tilgangsrettighetene = the access rights / permissions

So this sentence is talking about one specific access right or permission.

Er fjernet means literally is removed, but in natural English it is often understood as has been removed.

• er = is / are
• fjernet = removed

In Norwegian, være + past participle is often used to describe a current state or result. So Tilgangsrettigheten er fjernet focuses on the fact that the access right is now gone.

This is very common in notices, system messages, and formal language.

You can think of it as a past participle of the verb å fjerne = to remove.

In this sentence, it behaves a lot like an adjective describing the state of the noun:

• Rettigheten er fjernet = The permission is removed / has been removed.

So for a learner, the simplest way to understand it is:

• å fjerne = to remove
• fjernet = removed

Yes, it is passive in meaning.

The sentence does not say who removed the access right. It only tells you the result:

• Tilgangsrettigheten er fjernet.

An active version would name the doer, for example:

• Administratoren har fjernet tilgangsrettigheten.
  = The administrator has removed the access right.

So the original sentence keeps the focus on the permission itself, not on the person or system that removed it.

Both are possible, but they emphasize slightly different things.

• er fjernet = the access right is now in a removed state / has been removed
• ble fjernet = the access right was removed

So:

• er fjernet focuses more on the current result
• ble fjernet focuses more on the past event

In a system message, er fjernet is very natural because the important thing is the current status.

The last part of the compound, rettighet, determines the gender of the whole word.

Rettighet is a common-gender noun in Bokmål, so you get:

• en tilgangsrettighet
• tilgangsrettigheten

That is why the definite ending is -en.

Yes, but it does not mean exactly the same thing.

• Tilgangen er fjernet = The access is removed
• Tilgangsrettigheten er fjernet = The access right / permission is removed

Tilgangen is broader and can mean access in general.
Tilgangsrettigheten sounds more specific and technical, as if a particular permission or authorization in a system has been removed.

So the original sentence sounds like something you might see in IT, administration, or account settings.

The plural version would be:

• Tilgangsrettighetene er fjernet.

That means The access rights / permissions have been removed.

Compare:

• Tilgangsrettigheten er fjernet. = one permission
• Tilgangsrettighetene er fjernet. = several permissions
