Poengtavlen er tydelig.

Because Norwegian normally writes compound nouns as a single word.

Here, poeng + tavle becomes poengtavle.

This is very common in Norwegian. Where English may use two words, Norwegian often uses one:

• score board → poengtavle
• football match → fotballkamp

So poengtavlen is not unusually long by Norwegian standards.

The -en marks the noun as definite singular.

• poengtavle = a scoreboard / a points table
• poengtavlen = the scoreboard / the points table

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

Yes, often you can.

Tavle is a feminine noun in Bokmål, and many feminine nouns can take either:

• -a in the definite singular
• or -en in the definite singular

So both of these can be acceptable in Bokmål:

• poengtavla
• poengtavlen

Which one sounds more natural can depend on dialect, personal style, and whether someone prefers more feminine forms or more common-gender/masculine-style forms.

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

It links the subject poengtavlen with the description tydelig, just like English is:

• Poengtavlen er tydelig.
• The scoreboard is clear.

This is a very basic and common sentence pattern in Norwegian:

• Noun + er + adjective

Because tydelig is being used after the verb er, so it is a predicative adjective.

In this position, Norwegian adjectives agree mainly with gender and number, not with definiteness the way they do before a noun.

Here the subject is singular, so tydelig is the correct form.

Also, adjectives ending in -ig usually have the same form in:

• singular common gender
• singular neuter

For example:

• en tydelig tekst
• et tydelig signal
• tekstene er tydelige

So tydelige would be used for plural, not here.

It usually means something like:

• clear
• easy to read
• easy to see
• obvious

With poengtavlen, the most natural idea is often that the scoreboard is clear or easy to read.

Depending on context, it could also mean that the scoreboard makes the result or situation obvious.

So the exact nuance depends on what is happening around the sentence.

Yes, it is grammatical and natural.

That said, in real life, a Norwegian speaker might choose a more specific adjective depending on what they mean:

• Poengtavlen er synlig. = The scoreboard is visible.
• Poengtavlen er lett å lese. = The scoreboard is easy to read.
• Stillingen er tydelig. = The score/standing is clear.

But Poengtavlen er tydelig is still a perfectly acceptable sentence.

A rough learner-friendly version would be:

po-eng-tav-len er TY-de-lig

A few notes:

• poeng is usually pronounced as two syllables.
• ty begins with the Norwegian y sound, which does not exist in standard English.
• The ending of tydelig may sound lighter in natural speech than an English speaker expects.

You do not need perfect pronunciation right away; the most important thing is recognizing the words and stress pattern.

This sentence is standard Bokmål.

In Nynorsk, you would more likely see:

Poengtavla er tydeleg.

So the main differences are:

• tavlen → tavla
• tydelig → tydeleg

You can do that very easily:

• Er poengtavlen tydelig? = Is the scoreboard clear?
• Poengtavlen er ikke tydelig. = The scoreboard is not clear.

This gives you a very useful pattern:

• statement: Poengtavlen er tydelig.
• question: Er poengtavlen tydelig?
• negative: Poengtavlen er ikke tydelig.
