Vi skal montere sengen.

Vi means we.

Yes, in a normal Norwegian sentence, you usually need to include the subject, just like in English. So Vi skal montere sengen needs vi to show who is doing the action.

Norwegian does not usually drop the subject the way some other languages do.

Here, skal means something like will, are going to, or are supposed to, depending on context.

In Vi skal montere sengen, it most naturally suggests:

• We are going to assemble the bed
• We will assemble the bed

Skal is a modal verb, and it is very common in Norwegian.

A few common uses of skal:

• future: Jeg skal dra i morgen — I’m leaving tomorrow
• intention/plan: Vi skal spise snart — We’re going to eat soon
• obligation/instruction: Du skal gjøre leksene dine — You must/are supposed to do your homework

So the exact English translation depends on context.

Because after a modal verb like skal, Norwegian normally uses the infinitive without å.

So:

• Vi skal montere sengen
• not Vi skal å montere sengen

This is similar to English:

• We will assemble the bed
• not We will to assemble the bed

Other common modal verbs that work the same way include:

• kan — can
• vil — want to / will
• må — must
• bør — should

Examples:

• Jeg kan hjelpe — I can help
• Hun vil spise — She wants to eat
• Du må gå — You must go

Montere usually means assemble, install, or put together.

In the sentence Vi skal montere sengen, it most likely means assemble or put together, especially if it is a bed that comes in parts.

It is not always exactly the same as build.
For example:

• montere en seng — assemble a bed
• montere en hylle — install/assemble a shelf

A related everyday verb is sette sammen, which also means put together.

So in many situations, both could work:

• Vi skal montere sengen
• Vi skal sette sammen sengen

But montere can sound a bit more like assembling/installing something in a practical or technical sense.

Sengen means the bed, while seng means bed.

Norwegian often adds the definite article to the end of the noun instead of putting a separate word in front, so:

• en seng — a bed
• sengen — the bed

So:

• Vi skal montere en seng = We are going to assemble a bed
• Vi skal montere sengen = We are going to assemble the bed

This ending is one of the most important features of Norwegian nouns.

Because in Norwegian, the definite article is often attached as a suffix to the noun.

For common-gender nouns like seng, the pattern is:

• en seng — a bed
• sengen — the bed

This is different from English, where the comes before the noun.

Very common examples:

• en bil — a car

• bilen — the car

• en stol — a chair

• stolen — the chair

• en hund — a dog
• hunden — the dog

So sengen is completely normal Norwegian grammar.

Seng is usually a common gender noun in Bokmål, so the indefinite form is en seng.

That matters because it affects the definite form:

• en seng — a bed
• sengen — the bed

If it were a neuter noun, the pattern would be different, for example:

• et hus — a house
• huset — the house

So knowing the gender helps you form the noun correctly.

This is the normal Norwegian main-clause word order:

subject + finite verb + infinitive + object

So:

• Vi = subject
• skal = finite verb
• montere = infinitive
• sengen = object

This is very similar to English:

• We will assemble the bed

So the sentence structure is quite straightforward.

Yes. In a yes/no question, Norwegian usually puts the finite verb before the subject.

Statement:

• Vi skal montere sengen. — We are going to assemble the bed.

Question:

• Skal vi montere sengen? — Are we going to assemble the bed?

This verb-before-subject pattern is very common in Norwegian questions.

A rough pronunciation guide for an English speaker could be:

vee skahl mon-TEH-reh SENG-en

A few notes:

• vi sounds like vee
• skal has a broad a, somewhat like skahl
• montere has four syllables: mon-te-re
• sengen has two syllables: seng-en

The g in sengen is pronounced here.

Pronunciation varies somewhat by region, but this approximation is good enough for a learner.

Yes, absolutely.

Vi skal sette sammen sengen also means We are going to put the bed together.

The difference is mainly nuance:

• montere can sound a bit more formal, practical, or technical
• sette sammen is very common and transparent in everyday speech

Both are natural, and which one sounds best can depend on context.

This sentence is standard Bokmål:

• Vi — Bokmål and also possible in Nynorsk
• skal — used in both
• montere — used in both
• sengen — this definite form is Bokmål

In Nynorsk, you would more likely see:

Vi skal montere senga

That is because Nynorsk often prefers -a as the definite ending for many feminine nouns, while Bokmål commonly allows -en forms for many nouns that are treated as common gender.
