Questions & Answers about Det, hun siger, lyder vigtigt.
In Danish, det can be used to mean that / the thing / what in this kind of structure.
So:
- det = that / the thing
- hun siger = she says
Together, det, hun siger literally feels like that which she says, and in natural English we usually translate that as what she says.
So the sentence structure is:
- Det, hun siger = the subject
- lyder vigtigt = sounds important
Because Danish often leaves the relative pronoun out when it is not the subject of the relative clause.
In this sentence, the missing word would be the object of siger:
- hun siger [det] = she says [it]
So Danish can simply say:
- det, hun siger
You may also see:
- det, som hun siger
But without som is very common and natural here.
