Hvis vejret er dårligt, bliver vi hjemme.

Hvis means if. It introduces a condition:

• Hvis vejret er dårligt = If the weather is bad
• bliver vi hjemme = we stay at home

So the whole sentence is a standard if-clause + main clause structure.

Vejr means weather, while vejret means the weather.

In Danish, abstract things like weather are often spoken about with the definite form when you mean the weather in general or the weather in a particular situation:

• vejret = the weather

So Hvis vejret er dårligt is the natural way to say If the weather is bad.

Because vejr is a neuter noun in Danish, and adjectives used with er must agree with the noun.

• common gender: dårlig
• neuter: dårligt

Since vejr is neuter, you say:

• vejret er dårligt

This is similar to other neuter nouns:

• et hus er stort = a house is big
• vejret er dårligt = the weather is bad

This is because Danish uses verb-second word order in main clauses.

When the sentence begins with something other than the subject, such as an if-clause, the finite verb comes before the subject in the main clause:

• normal order: Vi bliver hjemme
• after an opening clause: Hvis vejret er dårligt, bliver vi hjemme

So the pattern is:

• opening clause
• verb
• subject
• rest of sentence

This inversion is very common in Danish.

Yes, blive often means become, but it can also mean remain or stay depending on context.

Here, bliver vi hjemme means:

• we stay home
• literally, something like we remain at home

So in this sentence, bliver does not mean become.

In Danish, hjem and hjemme are related but used differently.

• hjem usually expresses movement toward home
• hjemme expresses location at home

Compare:

• Vi går hjem = We go home
• Vi er hjemme = We are at home
• Vi bliver hjemme = We stay at home

Since there is no movement here, hjemme is correct.

Yes. Derhjemme also means at home, and in many contexts it works well.

• Vi bliver hjemme
• Vi bliver derhjemme

Both are possible, but hjemme is shorter and very natural here. Derhjemme can sound a little more specific or emphatic, depending on context.

The comma separates the if-clause from the main clause:

• Hvis vejret er dårligt, = subordinate clause
• bliver vi hjemme. = main clause

In standard Danish writing, this comma is normal and helps show the sentence structure clearly.

Yes. Danish often uses the present tense to talk about the future when the meaning is clear from context.

So:

• Hvis vejret er dårligt, bliver vi hjemme

can mean:

• If the weather is bad, we’ll stay home

This is very natural in Danish and similar to English, which also often uses present tense in if-clauses.

Yes, you can say:

• Hvis vejret er dårligt, så bliver vi hjemme.

Here, så means something like then. It is optional in many sentences like this.

Both versions are natural:

• Hvis vejret er dårligt, bliver vi hjemme.
• Hvis vejret er dårligt, så bliver vi hjemme.

The version without så is slightly more neutral and compact.
