Hun overlevede ulykken.

• Hun = she
• overlevede = survived
• ulykken = the accident

So the full sentence means She survived the accident.

Overlevede is the past tense of overleve (to survive).

• at overleve = to survive
• overlever = survives / is surviving
• overlevede = survived
• har overlevet = has/have survived

So this sentence is in the simple past, just like She survived the accident.

The ending -en shows that the noun is definite, meaning the accident, not just an accident.

The basic noun is:

• en ulykke = an accident

Its definite form is:

• ulykken = the accident

This is very common in Danish: instead of putting a separate word like English the before the noun, Danish often adds the definite ending directly to the noun.

This is a spelling change that happens in some Danish nouns when endings are added.

• en ulykke
• ulykken

The double k helps preserve the short vowel sound before it. You do not need to invent this yourself every time from pure logic; it is something you gradually get used to by seeing common noun patterns.

Yes. This sentence follows normal Danish subject–verb–object order:

• Hun = subject
• overlevede = verb
• ulykken = object

So:

• Hun overlevede ulykken = She survived the accident

This is the standard order for a simple statement.

Yes. That means She has survived the accident.

The difference is:

• Hun overlevede ulykken = She survived the accident
  This is simple past, often used for a completed event in the past.

• Hun har overlevet ulykken = She has survived the accident
  This connects the past event more directly to the present.

In many everyday situations, Danish often uses the simple past where English might prefer the present perfect, depending on context.

Here it takes a direct object.

• at overleve noget = to survive something

So:

• Hun overlevede ulykken = She survived the accident

You do not need a preposition here. English works the same way in this sentence.

A rough learner-friendly guide is:

• Hun ≈ hoon
• overlevede ≈ OH-vər-lay-və-thə
• ulykken ≈ oo-LUCK-en

But Danish pronunciation is tricky, and this is only approximate.

A few points:

• Hun is often pronounced more like hun with a soft, short vowel, not exactly like English hoon.
• The d in overlevede is a soft Danish d, not a strong English d.
• The y in ulykken is not like English y. It is a rounded front vowel that English does not really have.

If you want to sound natural, it is best to listen to native audio for this sentence.

Normally, hun is only capitalized at the beginning of a sentence, as in this example:

• Hun overlevede ulykken.

In the middle of a sentence, it would usually be lowercase:

• Jeg ved, at hun overlevede ulykken.
  = I know that she survived the accident.

The dictionary form is ulykke, and it is a common gender noun:

• en ulykke = an accident
• ulykken = the accident

When you learn Danish nouns, it is best to memorize them with their article:

• en ulykke, not just ulykke

That helps you build the definite form correctly later.

Yes, Hun overlevede ulykken is completely natural and idiomatic Danish.

It is short, clear, and exactly the kind of sentence a native speaker would say if they wanted to state that a woman or girl survived an accident.
