Jeg bliver hjemme, hvis jeg er syg og har ondt i maven.

In Danish, blive hjemme means to stay home or to remain at home. It focuses on the decision or result of not going out.

• Jeg bliver hjemme = I’m staying home / I will stay home
• Jeg er hjemme = I am at home

So in this sentence, bliver hjemme is the natural choice because the idea is I stay home if I am sick.

Hjemme means at home.

It is different from hjem, which usually means home as a destination:

• Jeg er hjemme = I am at home
• Jeg går hjem = I am going home

So bliver hjemme literally means stay at home.

After hvis meaning if, Danish normally uses regular subordinate-clause word order:

• hvis jeg er syg = if I am sick

That means the subject comes before the verb, just as in a normal statement inside the clause:

• jeg er syg = I am sick

So this part is very straightforward.

Because the subject jeg already applies to both verbs:

• jeg er syg
• [jeg] har ondt i maven

Danish often leaves out the repeated subject when the same subject continues in the same clause.

So:

• hvis jeg er syg og har ondt i maven

means:

• if I am sick and have a stomach ache

This works the same way in English.

Literally, it means something like have pain in the stomach/belly.

Breakdown:

• har = have
• ondt = painful / pain
• i = in
• maven = the stomach / the belly

Idiomatic English translation:

• have a stomach ache
• have pain in my stomach

In Danish, this expression is very common.

Ondt is the neuter form of ond, but in this expression it functions as part of a fixed phrase: at have ondt = to be in pain / to hurt.

Examples:

• Jeg har ondt i hovedet = My head hurts / I have a headache
• Hun har ondt i ryggen = Her back hurts
• Vi har ondt i benene = Our legs hurt

So here you should learn have pain as the set expression have ondt.

Danish often uses the definite form of body parts where English prefers a possessive.

So Danish says:

• jeg har ondt i maven
  literally: I have pain in the stomach

But English usually says:

• my stomach hurts
• I have a stomach ache
• I have pain in my stomach

This pattern is very common with body parts in Danish.

It can mean both sick and ill, depending on context.

• Jeg er syg = I am sick / ill

In everyday English, sick is usually the most natural translation, but ill is also correct in many contexts.

Danish comma rules often place a comma before a subordinate clause, and hvis jeg er syg og har ondt i maven is a subordinate clause.

So:

• Jeg bliver hjemme, hvis jeg er syg ...

This comma is standard in Danish writing.

Grammatically, it is present tense:

• Jeg bliver hjemme = literally present tense

But in Danish, just like in English, the present tense is often used for future meaning when the context is clear.

So the sentence can mean:

• I stay home if I am sick and have a stomach ache
• I will stay home if I am sick and have a stomach ache

Both are possible depending on context.

Yes. That would change the meaning.

• og = and
• eller = or

So:

• hvis jeg er syg og har ondt i maven = if I am sick and have a stomach ache
• hvis jeg er syg eller har ondt i maven = if I am sick or have a stomach ache

The original sentence requires both conditions together.

In careful pronunciation, bliver is roughly BLI-ver, but in normal spoken Danish it is often reduced.

A learner-friendly approximation is:

• bliver ≈ BLI-vuh

The r at the end is not pronounced like a strong English r. Danish pronunciation is often softer and more reduced than the spelling suggests.

Yes. If you start with the if-clause, the main clause verb must come before the subject because Danish is a V2 language in main clauses.

So you can say:

• Hvis jeg er syg og har ondt i maven, bliver jeg hjemme.

Notice the word order:

• not hvis ..., jeg bliver hjemme
• but hvis ..., bliver jeg hjemme

That is a very important Danish pattern.
