Vi møtes igjen i morgen.

Because å møtes means to meet each other / to get together.

• Vi møtes = we meet / we are meeting each other
• Vi møter usually means we meet someone/something in the sense of we meet them, we face them, or we encounter them

So:

• Vi møtes i morgen = We’re meeting tomorrow
• Vi møter læreren i morgen = We’re meeting the teacher tomorrow

In this sentence, the idea is reciprocal: the people are meeting one another.

Formally, it looks like the -s passive/reflexive type of form, and historically that is part of what is going on. But in everyday learning terms, it is best to treat å møtes as a common verb meaning to meet each other.

So in this sentence, møtes is not really being used like an English passive such as is met. It functions more like a reciprocal idea:

• Vi møtes = We meet each other

This is a very common pattern in Norwegian.

Norwegian often uses the present tense for the future when the time is clear from context.

Here, i morgen already tells you the action happens in the future, so Vi møtes igjen i morgen is completely natural.

This works much like English:

• We meet again tomorrow
• We’re meeting again tomorrow

Norwegian can also use other future-like forms, such as:

• Vi skal møtes igjen i morgen

But the simple present is very common for planned or expected future events.

Here, igjen means again.

So the sentence suggests that the people have met before, and they will meet another time tomorrow.

A few examples:

• Vi sees igjen = We’ll see each other again
• Prøv igjen = Try again

In some contexts, igjen can also mean back, but here again is the right meaning.

That word order is very natural in Norwegian.

• Vi møtes igjen i morgen

Here the structure is roughly:

• Vi = subject
• møtes = verb
• igjen = again
• i morgen = tomorrow

The sentence flows naturally this way: first the action, then the idea of repetition, then the time.

Other word orders are possible, but they can sound different in emphasis:

• I morgen møtes vi igjen = Tomorrow, we meet again
  This puts extra focus on tomorrow.

The original sentence is a very standard, neutral way to say it.

Usually, Vi møtes igjen i morgen is the more natural choice.

If you say Vi møtes i morgen igjen, it may sound marked or unusual, and it can suggest a different emphasis, almost as if again is being added afterward.

So for a normal sentence, use:

• Vi møtes igjen i morgen

That is the safest and most idiomatic version.

I morgen means tomorrow, and in standard Norwegian it is written as two words.

This is just the normal fixed expression:

• i dag = today
• i morgen = tomorrow

Even though English uses one word, Norwegian does not here.

Because i morgen is a fixed time expression, not a phrase meaning in the morning.

Compare:

• i morgen = tomorrow
• om morgenen = in the morning
• i morges = this morning

So morgen in i morgen is part of an established expression and does not need an article.

Yes, in natural English that is often a very good translation.

Even though møtes comes from å møtes (to meet each other), English may use either:

• We’ll meet again tomorrow
• We’ll see each other again tomorrow

The best English version depends on context. If it is just about getting together, meet again is a direct match. If the focus is simply that the people will be together again, see each other again can sound very natural too.

You would usually put ikke after the verb:

• Vi møtes ikke igjen i morgen.

This means:

• We are not meeting again tomorrow.

That follows normal Norwegian word order in a main clause:

• subject + verb + ikke

Yes, often you can.

• Vi sees igjen i morgen = We’ll see each other again tomorrow

This is very common and natural in Norwegian.

The difference is small:

• møtes focuses on meeting
• sees focuses on seeing each other

In many everyday situations, both work well.

A learner-friendly approximation is something like MUR-tehs or MØ-tehs, but the vowel ø does not exist in standard English, so it takes practice.

A few pronunciation notes:

• mø has the Norwegian ø sound
• the t is clearly pronounced
• the final -es is light and unstressed

If pronunciation is your goal, the hardest part is usually ø. It is not the same as o or u in English.

It is neutral and completely normal in both speech and writing.

It is not especially formal, but it is not slangy either. You could use it in everyday conversation, messages, or normal written Norwegian.

So Vi møtes igjen i morgen is a very standard sentence.
