Informasjonen er tilgjengelig.

Because -en is the definite ending, like the in English.

• informasjon = information
• informasjonen = the information

In Norwegian, the definite article is usually attached to the noun as an ending instead of being a separate word. So where English says the information, Norwegian says informasjonen.

Norwegian usually puts definiteness on the noun itself.

So instead of:

• English: the information

you get:

• Norwegian: informasjonen

This is one of the biggest differences from English. The noun carries the idea of the through its ending.

Er is the present tense of å være (to be).

So:

• jeg er = I am
• du er = you are
• informasjonen er = the information is

Norwegian does not change the present tense form for different persons the way English does. It is always er in the present tense.

Here, tilgjengelig is an adjective meaning something like available or accessible.

In this sentence, it comes after er, so it is being used predicatively:

• Informasjonen er tilgjengelig.
• The information is available.

This is similar to English adjectives after to be:

• The book is interesting.
• The room is clean.

Because it is describing a singular subject in a predicate position after er.

In this sentence:

• Informasjonen = singular
• so the adjective stays as tilgjengelig

If you had a plural subject, the adjective would usually change:

• Opplysningene er tilgjengelige. = The details are available.

So yes, Norwegian adjectives can change, but in this sentence the basic form is the correct one.

Yes, but then the structure changes.

After the noun phrase is already complete:

• Informasjonen er tilgjengelig.
• The information is available.

Before the noun:

• tilgjengelig informasjon
• available information

So both are possible, but they are used differently:

• Informasjonen er tilgjengelig. → full sentence
• tilgjengelig informasjon → noun phrase, not a full sentence by itself

This is the normal word order for a simple main clause in Norwegian:

• subject + verb + complement

So:

• Informasjonen = subject
• er = verb
• tilgjengelig = complement/adjective

This matches basic English word order quite closely:

• The information is available.

Norwegian is often called a verb-second language, but in a simple statement like this, that just gives the same order you would expect anyway.

A natural plural version would be something like:

• Opplysningene er tilgjengelige.
• The details / the pieces of information are available.

This shows two changes:

• the noun is plural
• the adjective becomes tilgjengelige

With informasjon, Norwegian often treats it as an uncountable mass noun, like English information, so the singular sentence is very natural.

Yes, very often.

Just like in English, informasjon is commonly used as a mass noun:

• Jeg trenger informasjon. = I need information.

That is why Informasjonen er tilgjengelig feels very natural: it refers to a specific body of information, not to separate individual items.

If you want to talk about separate items, Norwegian often uses other nouns such as:

• opplysninger = details / pieces of information

A simple learner-friendly approximation is:

• til-YENG-uh-li

A few helpful notes:

• gj often sounds like English y
• the stress is on the middle part: -YENG-
• the final g is weak or not clearly pronounced in everyday speech

You do not need perfect pronunciation right away; the most important thing is recognizing the word and using it correctly.

It is neutral and very natural. You could see or hear it in many contexts:

• on a website
• in an app
• in customer service
• in official or practical communication

It is a standard, useful sentence for saying that something can now be accessed or used.
