I sin ansøgning forklarer hun, hvorfor den stilling passer bedre til hendes hverdag.

Because Danish often puts a time phrase, place phrase, or other element first for emphasis or style.

Here, I sin ansøgning means in her application, and it is being placed first to set the scene.

When something other than the subject comes first in a Danish main clause, Danish uses V2 word order: the finite verb must come in the second position.

So:

• Hun forklarer ... = neutral order
• I sin ansøgning forklarer hun ... = fronted phrase, so the verb forklarer comes before hun

This is very common in Danish.

This is because of the Danish V2 rule in main clauses.

In a main clause, the finite verb usually comes in the second position, not necessarily right after the subject.

In this sentence, the first element is:

• I sin ansøgning

So the verb must come next:

• I sin ansøgning forklarer hun ...

If you started with the subject, then you would get:

• Hun forklarer i sin ansøgning ...

Both are correct, but the word order changes because the first element changes.

Because sin/sit/sine is the reflexive possessive in Danish. It is used when the possessor is the same as the subject of the clause.

Here, the subject is hun, and the application belongs to her, so Danish uses sin:

• hun ... sin ansøgning

This is different from English, which just uses her in both cases.

A useful comparison:

• Hun elsker sin hund. = She loves her own dog.
• Hun elsker hendes hund. = She loves another woman’s dog.

So in your sentence, sin shows that the application is her own.

Because sin/sit/sine agrees with the noun it belongs to, not with the person.

The noun here is ansøgning, and ansøgning is a common gender singular noun, so you use sin.

The pattern is:

• sin
  • common gender singular noun
• sit
  • neuter singular noun
• sine
  • plural noun

Examples:

• sin bil = her/his own car
• sit hus = her/his own house
• sine bøger = her/his own books

So:

• sin ansøgning is correct because ansøgning is common gender singular.

This is a very important point.

In the clause:

• hvorfor den stilling passer bedre til hendes hverdag

the subject is den stilling, not hun.

In Danish, sin/sit/sine normally refers back to the subject of its own clause. If you used sin hverdag here, it would grammatically point back to den stilling, which does not make sense.

So Danish uses hendes to refer back to hun, because hun is not the subject of this subordinate clause.

That is why:

• ... hun forklarer ... → subject of main clause = hun
• ... hvorfor den stilling passer ... → subject of subordinate clause = den stilling

Therefore:

• sin ansøgning = correct in the main clause
• hendes hverdag = correct in the subordinate clause

Both forms can refer to the position/job, but they are used a little differently.

• stillingen = the definite form built into the noun
• den stilling = demonstrative-style definite phrase, often pointing more clearly to a particular one

In many contexts, den stilling feels like that/the position in question, especially when it is already known from the context.

So here, den stilling can suggest a specific position that has already been mentioned or is understood.

Danish often uses both patterns, but they are not always identical in tone or emphasis.

Because the verb here is passe til, which means to suit, to fit, or to be suitable for.

So:

• passe til noget = suit something / fit something

That is why Danish says:

• den stilling passer bedre til hendes hverdag

The preposition til is part of the normal pattern with this meaning of passe.

Without til, the sentence would not sound right here.

Because hvorfor means why, while fordi means because.

In this sentence, she explains why the position suits her daily life better. So Danish uses hvorfor to introduce an indirect question/explanation:

• forklarer hun, hvorfor ... = she explains why ...

If you used fordi, the structure would be different:

• Hun forklarer, fordi ... = She explains, because ...

That would mean something else. So hvorfor is the correct choice here.

Because in this part of the sentence, the clause introduced by hvorfor is a subordinate clause, and Danish subordinate clauses usually keep the subject before the verb in a more straightforward order.

So you get:

• hvorfor den stilling passer bedre til hendes hverdag

Structure:

• hvorfor = why
• den stilling = subject
• passer = verb
• bedre = comparative adverb
• til hendes hverdag = prepositional phrase

This is more like the normal subject + verb order you might expect.

Hverdag usually means everyday life, daily routine, or day-to-day life.

In this sentence, it refers to the practical rhythm of her normal life: work-life balance, schedule, family responsibilities, commuting, and so on.

So hendes hverdag is not just her day in the literal sense. It means something more like:

• her daily life
• her usual routine
• the way her normal life is organized

Bedre is the comparative form of god in this kind of meaning, and here it works like better in English.

So:

• passer godt til = suits/fits well
• passer bedre til = suits/fits better

It shows comparison, even if the thing being compared is not stated explicitly. The implied meaning is that this position suits her daily life better than another option.

Usually, yes, especially in a sentence like this.

Ansøgning often means:

• an application
• very commonly a job application

Because the sentence also mentions den stilling (the position/job), the meaning here is clearly a job application.

So I sin ansøgning is best understood as in her application letter / in her job application.
