Vi reiser i desember.

In Norwegian, the present tense is very often used for planned future actions, especially when there is a time expression like i desember.

So Vi reiser i desember literally looks like We travel in December, but it naturally means We are traveling in December / We will travel in December.

This is very similar to English sentences like:

• We leave in December
• We’re traveling in December

You could also say Vi skal reise i desember, which is a bit more explicitly future-oriented, like We are going to travel in December.

Reiser is the present tense of å reise, which usually means to travel or to go on a trip.

Depending on context, it can sometimes feel like:

• travel
• leave
• go away

In this sentence, reiser most naturally means are traveling / will travel.

Norwegian uses i with months and many other time periods.

So you say:

• i desember = in December
• i januar = in January
• i sommer = in the summer
• i morgen is different and means tomorrow, but that is a fixed expression

For months, i is the normal choice.

Yes. Vi is the Norwegian subject pronoun meaning we.

Examples:

• Vi bor her = We live here
• Vi kommer snart = We are coming soon
• Vi reiser i desember = We are traveling in December

This sentence has the basic Norwegian word order:

Subject + verb + time expression

So:

• Vi = subject
• reiser = verb
• i desember = time phrase

That makes it a very standard main-clause sentence.

If you move the time expression to the front, Norwegian uses verb-second word order:

• I desember reiser vi

Not:

• I desember vi reiser

Yes, absolutely.

Both are correct:

• Vi reiser i desember
• I desember reiser vi

The difference is mainly focus:

• Vi reiser i desember is neutral.
• I desember reiser vi emphasizes December a bit more, as if answering When are you traveling?

In Norwegian, months are not capitalized unless they begin a sentence.

So:

• Vi reiser i desember
• Desember er kald i Norge

This is different from English, where December is always capitalized.

The same rule applies to:

• days of the week
• languages
• nationalities in many contexts

No. Norwegian normally does not use an article with months in this kind of expression.

So:

• i desember = in December

Not:

• i en desember
• i desemberen

Those would sound wrong here.

A rough pronunciation guide is:

• reiser ≈ RYE-ser
• desember ≈ deh-SEM-ber

A few useful notes:

• ei in reiser is usually like the English eye
• The r is pronounced, though exactly how it sounds depends on the dialect
• The stress in desember is on the second syllable

This sentence is standard Bokmål.

In Nynorsk, you would normally say:

• Vi reiser i desember
  or often
• Vi reiser i desember is still understandable, but many Nynorsk users would prefer Vi reiser i desember only depending on verb choice and style

A very common Nynorsk version would be:

• Vi reiser i desember or
• Vi dreg i desember for We’re leaving/traveling in December, depending on the verb chosen

For a learner, the important point is that Vi reiser i desember is perfectly normal Bokmål.

In this sentence, it most naturally refers to one planned trip in December.

But grammatically, the sentence itself does not force that meaning. Context decides.

For example:

• Vi reiser i desember usually means We’re traveling in December as a plan.
• In another context, it could theoretically mean We travel in December as a habit, but that is less likely without more context.

So the sentence is usually understood as a future plan.
