Questions & Answers about Han ligger bevisstløs på gulvet.
Because ligger tells you about the person’s position: he is in a lying position.
- Han er bevisstløs = He is unconscious.
- Han ligger bevisstløs på gulvet = He is lying unconscious on the floor.
So er would only describe his state, while ligger adds physical position as well.
This is a very common confusion.
- ligger = lies / is lying (state or position)
- legger = lays / puts down or lies down in some reflexive uses (action)
Compare:
- Han ligger på gulvet. = He is lying on the floor.
- Han legger boka på gulvet. = He puts the book on the floor.
- Han legger seg på gulvet. = He lies down on the floor.
So in your sentence, ligger is correct because it describes the result/state, not the action of moving down.
Yes. In Norwegian, the present tense often covers both:
- English he lies
- English he is lying
So Han ligger bevisstløs på gulvet can naturally correspond to He is lying unconscious on the floor.
Norwegian does not usually need a separate progressive form like English is lying.
