Vi avgjør saken i morgen.

Because Norwegian very often uses the present tense for future meaning when the time is already clear from the context.

So Vi avgjør saken i morgen is completely natural and means that the decision will happen tomorrow.

This is similar to English sentences like:

• We leave tomorrow
• I meet her next week

Norwegian does not need a separate future form here.

If you want, you can also use skal:

• Vi skal avgjøre saken i morgen

That sounds a bit more like we are going to / we intend to decide the matter tomorrow, but the original sentence is perfectly normal.

The infinitive is å avgjøre.

In this sentence:

• avgjør = present tense
• å avgjøre = to decide / to settle / to determine

This verb follows the pattern of gjøre → gjør, so it does not use the regular present ending -er that many learners expect.

Compare:

• å kaste → kaster
• å kjøpe → kjøper
• å gjøre → gjør
• å avgjøre → avgjør

So avgjør is the correct present form.

It usually means to decide, to settle, or to determine.

In a sentence like Vi avgjør saken i morgen, it often sounds a little more formal or final than just bestemme.

Possible nuances:

• avgjøre = make a final decision, settle something, determine the outcome
• bestemme = decide, choose, make up one’s mind

So here avgjøre suggests that the matter will be resolved tomorrow, not just casually discussed.

Because saken is the definite singular form of sak.

• sak = a case / a matter / an issue
• saken = the case / the matter / the issue

Norwegian usually adds the definite article to the end of the noun instead of putting a separate word in front like English the.

So:

• en sak = a case / a matter
• saken = the case / the matter

That is why there is no separate word for the in the sentence.

All three can be possible, depending on context.

Sak is a broad word in Norwegian. It can refer to:

• a legal case
• a practical matter
• an issue under discussion
• a subject or cause in some contexts

So in Vi avgjør saken i morgen, the exact English word depends on the situation:

• the case if it is legal or formal
• the matter if it is general
• the issue if people are discussing a problem or question

I morgen is simply the normal Norwegian expression for tomorrow.

It is a fixed time expression, so learners should usually just memorize it as a whole.

Some common time expressions are:

• i dag = today
• i morgen = tomorrow
• i kveld = tonight / this evening

Even though i often means in, in expressions like i morgen it is best to think of the whole phrase as one unit.

Because that is the most neutral word order in a main clause:

• subject + verb + object + time expression

So:

• Vi = subject
• avgjør = verb
• saken = object
• i morgen = time expression

This order is very common in Norwegian.

So Vi avgjør saken i morgen sounds natural and neutral.

If you move the time expression to the front, that is also correct, but the structure changes:

• I morgen avgjør vi saken

That brings more focus to tomorrow.

Yes, absolutely.

That sentence is correct and means the same thing, but now i morgen is emphasized a bit more because it comes first.

This is a very useful example of Norwegian V2 word order in main clauses:

• If something other than the subject comes first, the verb still stays in second position.

So:

• Vi avgjør saken i morgen
• I morgen avgjør vi saken

Both are correct.

But notice that you do not say:

• I morgen vi avgjør saken ❌

That is wrong in a normal main clause.

Both are natural, but there is a small difference in feel.

• Vi avgjør saken i morgen = a straightforward statement about what happens tomorrow
• Vi skal avgjøre saken i morgen = stronger sense of plan, intention, or arrangement

Very roughly:

• simple present = we decide / we’re deciding tomorrow
• skal
  • infinitive = we will / are going to decide tomorrow

In many everyday situations, either one could work.

A rough pronunciation guide is:

• avgjør ≈ AHV-yur

A few important points:

• gj here sounds like a y sound, not a hard English g
• ø does not exist in English; it is a rounded vowel, somewhere in the area of the vowel in French peur or German schön
• the final r may sound different depending on dialect

So do not pronounce it like:

• av-gor ❌
• av-jor with an English j like in job ❌

A better approximation is av-YUR, though that is still only approximate.

In normal use, avgjøre is treated as one verb, written as one word.

So in this sentence, you keep it together:

• Vi avgjør saken i morgen

You do not split it up in the way learners may know from German separable verbs.

It is helpful to recognize that av is part of the word historically, but in ordinary modern Norwegian grammar, you should learn avgjøre as a single lexical item meaning to decide / settle.
