Har du ikke pakket solbrillene?

Because this is a yes/no question in Norwegian.

In Norwegian main-clause yes/no questions, the finite verb comes first:

• Har du ikke pakket solbrillene?
• literally: Have you not packed the sunglasses?

This is similar to English, where we also move the auxiliary verb to the front:

• You have not packed the sunglasses.
• Have you not packed the sunglasses?

So har is first because it is the auxiliary verb used to form the question.

Har pakket is the present perfect.

It is made from:

• har = present tense of å ha (to have)
• pakket = past participle of å pakke (to pack)

So:

• har pakket = have packed / has packed

In this sentence, it means something like:

• Haven’t you packed the sunglasses?

The present perfect is often used for something that should be completed by now or is relevant now.

Because after har, Norwegian uses the past participle, not the present tense.

Compare:

• du pakker = you pack / you are packing
• du har pakket = you have packed

So:

• pakker is a present-tense verb form
• pakket is the past participle

That is why har pakket is correct here.

In Norwegian, ikke usually comes after the finite verb and the subject in main-clause questions.

So the order here is:

• Har = finite verb
• du = subject
• ikke = negation
• pakket = past participle
• solbrillene = object

Pattern:

• Har + subject + ikke + past participle + object?

That gives:

• Har du ikke pakket solbrillene?

This word order is very natural in Norwegian.

Yes, very often it does.

A negative question like Har du ikke pakket solbrillene? often suggests that the speaker thought the action would already be done, or is surprised that it may not be done.

Depending on context, it can sound like:

• Haven’t you packed the sunglasses?
• You haven’t packed the sunglasses?
• Didn’t you pack the sunglasses?
  (depending on how English chooses to express the same idea)

So the sentence may carry a feeling of:

• surprise
• reminder
• mild criticism
• checking an assumption

Context and intonation matter a lot.

Solbrillene means the sunglasses.

It comes from:

• solbrille = a sunglass
• solbriller = sunglasses
• solbrillene = the sunglasses

So this is the definite plural form.

Norwegian often adds the definite article as an ending:

• en solbrille = a sunglass
• solbrillen = the sunglass
• solbriller = sunglasses
• solbrillene = the sunglasses

Because Norwegian usually puts definiteness on the noun itself as an ending.

In English, you say:

• the sunglasses

In Norwegian, you usually say:

• solbrillene

The ending -ne marks definite plural, so a separate word like the is not needed here.

This is a very common feature of Norwegian nouns.

Yes, but it means something slightly different.

• Har du ikke pakket solbrillene? = Haven’t you packed the sunglasses?
  This usually refers to specific sunglasses that both speaker and listener know about.

• Har du ikke pakket solbriller? = Haven’t you packed sunglasses?
  This is more general and indefinite.

So the version with solbrillene sounds more like a specific pair or a known item.

Because Norwegian does not use do-support the way English does.

In English, many questions and negatives need do/does/did:

• Did you pack the sunglasses?
• Don’t you have sunglasses?

Norwegian usually does this directly with the main verb or with an auxiliary, without adding an extra verb like do.

So Norwegian says:

• Pakket du solbrillene? = Did you pack the sunglasses?
• Har du ikke pakket solbrillene? = Haven’t you packed the sunglasses?

This is normal Norwegian structure.

The statement version is:

• Du har ikke pakket solbrillene.

That means:

• You have not packed the sunglasses.

Notice the difference in word order:

• statement: Du har ikke pakket solbrillene.
• question: Har du ikke pakket solbrillene?

In the question, the finite verb har moves to the front.

Sometimes, yes, depending on context.

The literal structure is Have you not packed the sunglasses?, so the closest English match is usually:

• Haven’t you packed the sunglasses?

But in natural English, people may also say:

• Didn’t you pack the sunglasses?
• You didn’t pack the sunglasses?

The exact English version depends on tone and situation.

Still, grammatically, the Norwegian sentence uses the present perfect: har pakket.

Yes, in a normal full sentence, the subject du is needed.

• Har du ikke pakket solbrillene? = Haven’t you packed the sunglasses?

Norwegian normally requires an explicit subject, just like English does.

You would not normally leave out du in a standard sentence like this.

Without ikke, the sentence becomes:

• Har du pakket solbrillene?

That means:

• Have you packed the sunglasses?

So the difference is:

• Har du pakket solbrillene? = neutral question
• Har du ikke pakket solbrillene? = negative question, often with surprise or expectation

Adding ikke changes both the grammar and the tone.
