Løken er hakket og klar til suppen.

In Norwegian, the definite article is usually attached to the end of the noun.

• løk = onion
• løken = the onion

So -en is the definite ending for this noun. Norwegian often says the equivalent of onion-the where English says the onion.

The dictionary form is løk.

You would normally learn it as:

• en løk = an onion
• løken = the onion

So in this sentence, the noun is singular and definite.

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

Here it links the subject løken with two descriptions:

• hakket = chopped
• klar til suppen = ready for the soup

So er works just like is in English.

It is a past participle of å hakke (to chop), but in this sentence it functions like an adjective.

So it describes the state of the onion:

• Løken er hakket = the onion is chopped

This is very common in Norwegian, just as in English when we say is chopped, is cooked, is finished, and so on.

That is a very common point of confusion.

After er, Norwegian uses the predicate form:

• Løken er hakket = the onion is chopped

Before a noun, you often get an attributive form:

• den hakkede løken = the chopped onion

So the difference is about position and function:

• after er: hakket
• before a definite noun: often hakkede

Because løk is a common-gender noun, and the adjective agrees with it.

• en løk → klar
• a neuter noun like et egg would take klart

Compare:

• Løken er klar = the onion is ready
• Egget er klart = the egg is ready

So klar matches the gender of løken.

Because this adjective is in predicate position, not directly in front of the noun.

In Norwegian, definiteness affects adjectives more clearly when they come before the noun:

• den klare suppen = the ready/clear soup

But after er, you usually use the normal predicate form:

• Suppen er klar
• Løken er klar

So even though løken is definite, klar stays klar here.

Here til means something like for.

So klar til suppen means the onion is ready to be used for the soup.

This is a very common pattern in Norwegian:

• klar til middag = ready for dinner
• klar til bruk = ready for use
• klar til å gå = ready to go

Suppen is the definite form, meaning the soup.

That suggests a specific soup is being talked about, not soup in general. For example, maybe you are already making a particular pot of soup, so the onion is ready for the soup.

If you said til suppe, it would sound more general, more like for soup as a category or purpose.

Yes, but it changes the meaning.

• klar til suppen = ready for the soup / ready to go into the soup
• i suppen = in the soup

So til suggests preparation for use, while i suggests location.

Ø is a vowel sound English does not really have.

A rough guide:

• it is somewhat similar to the vowel in French peu
• or German ö

It is not the same as o or u. If you are an English speaker, it may take practice to hear and say it clearly.

The structure is:

• Løken = subject
• er = verb
• hakket og klar til suppen = description of the subject

So this is a very normal Norwegian sentence pattern:

subject + verb + complement

The two descriptions hakket and klar til suppen are joined by og (and).

Yes. It sounds natural and idiomatic.

It is the kind of sentence you might hear in a kitchen or recipe context, where someone is describing the state of an ingredient. Norwegian often uses short, practical sentences like this.
