Risikoen er tydelig.

Because Norwegian usually adds the definite article to the end of the noun.

• en risiko = a risk
• risikoen = the risk

So -en here is doing the job that the does in English.

The dictionary form is risiko.

If you look it up, you would normally find:

• en risiko = a risk
• risikoen = the risk

So risikoen is the definite singular form of risiko.

Er is the present tense of å være, which means to be.

So:

• jeg er = I am
• du er = you are
• han/hun er = he/she is
• vi er = we are

Unlike English, Norwegian does not change the verb here depending on the subject. It is always er in the present tense.

Here, tydelig is the correct singular form.

A useful point is that in Norwegian, adjectives used after a verb like er are predicate adjectives, and they do not change just because the noun is definite.

So:

• En risiko er tydelig.
• Risikoen er tydelig.

Both use tydelig.

Also, adjectives ending in -ig often have the same form in singular, so you also get:

• et tydelig tegn = a clear sign

But in the plural, you would use tydelige:

• Risikoene er tydelige. = The risks are clear.

No, this is very standard word order for a simple statement.

The pattern is:

• Risikoen = subject
• er = verb
• tydelig = adjective/complement

So it works much like English:

• The risk is clear.

Norwegian main clauses often look very similar to English in short sentences like this.

Yes. Depending on context, tydelig can mean:

• clear
• obvious
• evident
• distinct

In this sentence, likely translations are:

• The risk is clear.
• The risk is obvious.
• The risk is evident.

So the exact English word depends on context.

You would say:

• den tydelige risikoen

This is different because now the adjective comes before the noun.

Notice two things:

• you add den
• tydelig becomes tydelige

So:

• Risikoen er tydelig. = The risk is clear.
• Den tydelige risikoen = The clear risk

That difference is very important in Norwegian.

You switch the verb and the subject:

• Er risikoen tydelig?

That means:

• Is the risk clear?

This is a very common Norwegian pattern for yes/no questions: verb + subject + rest

A rough learner-friendly pronunciation would be:

• Risikoen ≈ ri-si-KOO-en
• er ≈ air / ehr (depending on accent)
• tydelig ≈ TY-de-lig

Two notes:

• The y sound in tydelig is not a normal English y. It is a Norwegian vowel. Try saying ee while rounding your lips.
• In risikoen, the ending -oen is pronounced as separate vowels, so you can hear the extra syllable.

A more natural rhythm is something like:

• ri-si-KOO-en er TY-de-lig
