Hvis bolden rammer døren, bliver min far gal.

Hvis means if and introduces a condition. In this sentence, Hvis bolden rammer døren means If the ball hits the door.

A useful contrast is:

• hvis = if
• når = when

So Danish uses hvis because the speaker is talking about a possible situation, not something certain.

Bolden means the ball. In Danish, the definite article is usually added to the end of the noun instead of being a separate word in front.

So:

• en bold = a ball
• bolden = the ball

This is very common in Danish. The noun bold is a common gender noun, so its definite ending is -en.

For the same reason as bolden: døren means the door.

Compare:

• en dør = a door
• døren = the door

So both bolden and døren are definite forms.

Rammer is the present tense of ramme = to hit.

In Danish, verbs do not change according to the subject the way they do in English. So the same present-tense form is used with all persons:

• jeg rammer = I hit
• du rammer = you hit
• han/hun rammer = he/she hits
• bolden rammer = the ball hits

So rammer is simply the normal present-tense form.

Danish often uses the present tense for future meaning when the context already makes the future clear.

So:

• Hvis bolden rammer døren literally looks like If the ball hits the door
• bliver min far gal literally looks like my father becomes angry

But together they naturally mean something like If the ball hits the door, my dad will get angry.

This is very normal in Danish, especially in if-sentences.

This is a very important Danish word-order rule.

The sentence begins with a subordinate clause:

• Hvis bolden rammer døren

After that, the main clause follows:

• bliver min far gal

In Danish main clauses, the finite verb usually comes in second position. Because the if-clause is placed first, it counts as the first element, so the verb in the main clause must come immediately after it.

That is why you get:

• Hvis bolden rammer døren, bliver min far gal.

If you start with the main clause instead, the order is normal:

• Min far bliver gal, hvis bolden rammer døren.

Both are correct.

Bliver is the present tense of blive, which often means become.

So min far bliver gal literally means:

• my father becomes angry/mad

In natural English, this is usually translated as:

• my father gets angry
• my father will get mad

So bliver is not is here; it is more like gets or becomes.

Gal can mean different things depending on context. Here it means angry or mad.

So:

• min far bliver gal = my father gets angry / mad

In other contexts, gal can also mean crazy or wild, so learners should be careful not to assume it always means only one thing. In this sentence, angry is clearly the right meaning.

Often, yes.

Both can describe anger, but they are not always identical:

• sur = angry, cross, upset
• gal = mad, really angry, sometimes stronger or more emotional

In everyday speech, gal can sound a bit stronger or more dramatic than sur, though the exact tone depends on context and speaker.

The comma separates the subordinate clause from the main clause:

• Hvis bolden rammer døren, = subordinate clause
• bliver min far gal. = main clause

In standard written Danish, commas are often used to mark this boundary. So the comma helps show the structure of the sentence clearly.

Yes, absolutely. That version is also correct.

Compare:

• Hvis bolden rammer døren, bliver min far gal.
• Min far bliver gal, hvis bolden rammer døren.

The meaning is basically the same. The difference is mainly emphasis and information flow:

• starting with Hvis ... puts the condition first
• starting with Min far ... puts the main result first

This kind of word-order flexibility is very common in Danish, as long as the verb placement rules are followed.
