Questions & Answers about Hun er omgitt av familien.
Because hun is the subject form, meaning she.
In this sentence, hun is the person the sentence is about, so Norwegian uses hun:
- Hun er omgitt av familien. = She is surrounded by the family.
Henne is the object form, meaning her:
- Familien omgir henne. = The family surrounds her.
So the two sentences express a similar idea, but the grammar is different.
Omgitt is the past participle of the verb å omgi, which means to surround.
In this sentence, it works like an adjective after er:
- er omgitt = is surrounded
So it is not a separate basic dictionary word you would usually learn first; it comes from the verb å omgi.
Because omgir would make she the one doing the surrounding.
Compare:
Hun er omgitt av familien.
She is surrounded by the family.Hun omgir familien.
She surrounds the family.
So er omgitt is used when she is receiving the action/state, not performing it.
