Kommentaren er upassende.

Kommentaren is the definite form of kommentar, so it means the comment rather than a comment.

• en kommentar = a comment
• kommentaren = the comment

Norwegian usually adds the definiteness to the end of the noun, instead of using a separate word like the in English.

The ending -en is the common definite singular ending for many masculine nouns in Bokmål.

Here the base noun is:

• en kommentar = a comment

and the definite form becomes:

• kommentaren = the comment

This is a very common pattern:

• en bil → bilen
• en stol → stolen
• en kommentar → kommentaren

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

So:

• å være = to be
• er = is / am / are, depending on context

In this sentence, er means is:

• Kommentaren er upassende = The comment is inappropriate

This is the normal Norwegian word order for a simple statement:

subject + verb + complement

So:

• Kommentaren = subject
• er = verb
• upassende = adjective/complement

That is very similar to English:

• The comment
  • is
    • inappropriate

Many Norwegian adjectives do change depending on gender, number, or definiteness, but adjectives ending in -ende are often unchanged.

So upassende stays the same in many contexts:

• en upassende kommentar
• et upassende spørsmål
• upassende kommentarer
• Kommentaren er upassende

That makes this adjective relatively easy to use.

In this sentence, upassende is an adjective used after the verb er. That is called a predicative adjective.

Compare:

• en upassende kommentar = adjective before the noun
• Kommentaren er upassende = adjective after er

In both cases, upassende describes the comment.

A rough English-friendly guide might be:

kom-men-TA-ren er oo-PASS-en-de

A few helpful notes:

• r in Norwegian is usually clearer than in most English accents.
• The u in upassende is not exactly like English oo, but oo is a decent approximation.
• The stress is typically on -ta- in kommentaren and pass in upassende.

Exact pronunciation varies by dialect, but this approximation is good for a learner.

Yes. That would change the tense from present to past.

• Kommentaren er upassende = The comment is inappropriate
• Kommentaren var upassende = The comment was inappropriate

So the structure stays the same; only the verb changes.

In Bokmål, many nouns can be treated as either masculine or feminine, depending on usage and style, but kommentar is most commonly treated as masculine:

• en kommentar
• kommentaren

You will normally see this masculine pattern. Even in varieties of Bokmål that use more feminine forms, kommentar is usually not the kind of noun learners first meet as feminine.

Yes. Den kommentaren er upassende means That comment is inappropriate.

Compare:

• Kommentaren er upassende = The comment is inappropriate
• Den kommentaren er upassende = That comment is inappropriate

Adding den makes it more specific or contrastive, like pointing out a particular comment.

Norwegian often expresses the by adding an ending to the noun:

• en kommentar = a comment
• kommentaren = the comment

So instead of using a separate word like English the, Norwegian usually puts the definiteness on the noun itself.

However, when there is a demonstrative or certain other structures, you can also see an additional word:

• den kommentaren = that comment
• den upassende kommentaren = the inappropriate comment

In Norwegian, yes/no questions usually have verb first.

So:

• Kommentaren er upassende. = The comment is inappropriate.
• Er kommentaren upassende? = Is the comment inappropriate?

This is a very important pattern in Norwegian word order.

Yes. Depending on context, upassende can be translated in several similar ways, such as:

• inappropriate
• improper
• unsuitable
• out of place

In a sentence about a remark or behavior, inappropriate is often the most natural English choice.
