Hun er rasende.

Hun is the subject form of she.

In Hun er rasende, hun is doing the role of the subject, so hun is correct.

Use henne when the pronoun is an object, like her in English:

• Hun er rasende. = She is furious.
• Jeg ser henne. = I see her.

So a simple rule is:

• hun = she
• henne = her

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

So:

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

Norwegian does not change the present-tense form of the verb depending on the person the way English does. The same form er is used with all subjects.

Here, rasende is an adjective. It describes hun.

So the sentence has this structure:

• Hun = subject
• er = verb
• rasende = adjective describing the subject

This is very similar to English She is furious.

Many Norwegian adjectives ending in -ende have that form in all or almost all common uses. In other words, rasende is basically a fixed adjective form.

That means you can often see the same form regardless of gender or number:

• en rasende kvinne
• et rasende uvær
• rasende mennesker
• Hun er rasende
• Det er rasende

So unlike many other adjectives, rasende does not usually change its ending.

Yes. Historically, adjectives like rasende are related to verb forms, similar to English adjectives such as exciting or frightening.

But for a learner, the most useful thing is to treat rasende here simply as an adjective meaning something like furious or enraged.

You do not need to analyze it as a verb in this sentence.

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

subject + verb + complement

So:

• Hun = subject
• er = verb
• rasende = complement/adjective

This is very close to English word order.

If you turn it into a yes/no question, the verb comes first:

• Er hun rasende? = Is she furious?

That verb-second pattern is very important in Norwegian.

Yes. Sint is a very common word for angry.

The difference is mainly one of intensity and style:

• sint = angry
• rasende = furious / enraged

So rasende is stronger than sint.

Examples:

• Hun er sint. = She is angry.
• Hun er rasende. = She is furious.

A rough guide for an English speaker is:

• Hun ≈ hoon (but with a Norwegian u sound, which is more rounded than English oo)
• er ≈ like air, but shorter and often less clearly pronounced
• rasende ≈ RAH-sen-deh, with the stress usually on the first syllable: RA-sen-de

A few pronunciation notes:

• Norwegian r is often different from English r.
• The final -e in rasende is pronounced, unlike in many English words.
• In natural speech, er can be reduced and sound fairly weak.

Only if it starts the sentence, as it does here:

• Hun er rasende.

In the middle of a sentence, it is lowercase:

• Jeg tror hun er rasende.

Norwegian does not capitalize pronouns like she for special politeness or emphasis in ordinary modern usage.

No, not in a normal full sentence like this.

Norwegian usually requires the verb to be in sentences of this type:

• Hun er rasende. = correct
• Hun rasende. = not standard Norwegian

This is the same as English, where you also need is:

• She is furious.
• She furious. = incorrect

Use a full stop if it is a statement:

• Hun er rasende.

Use a question mark if you turn it into a question:

• Er hun rasende?

Use an exclamation mark if you want stronger emotion:

• Hun er rasende!

The basic sentence itself is a normal declarative statement, so a full stop is the most neutral choice.
