Questions & Answers about Hun studerer tre fag, men arbejder også i weekenden.
Danish, like English, uses different pronouns for the subject and the object:
- Hun = she (subject form)
- Hende = her (object form)
In this sentence, Hun is the subject of studerer (the one doing the studying), so you must use the subject form Hun, not Hende.
You would use hende after a verb or preposition where it is the object, e.g.
- Jeg kan godt lide hende. = I like her.
In coordinated clauses with the same subject, Danish often omits the repeated subject, especially in writing:
- Hun studerer tre fag, men arbejder også i weekenden.
The subject hun is understood to be the same in both parts:
- [Hun] studerer tre fag, men [hun] arbejder også i weekenden.
Including hun again is also correct:
- Hun studerer tre fag, men hun arbejder også i weekenden.
Leaving it out puts a bit more focus on the new information (arbejder også i weekenden).
