Having trouble getting my head around the rule. Does this mean that "Hvem spiser kjillinger?" could mean both "Who eats chickens?" and "Who do chickens eat?"
With what has already been explained above, it sort of makes sense (thanks, Linn!)
Is it because if you're referring to a thing (animal) that eats the horse, you'd use "det" or some kind of personal pronoun, rather than a simple "What" or "who"?
How would you differentiate between "what eats horses" and "what do horses eat" with little to no context? Which one is more common?
Then how would you say "What do the horses eat?" I'm new in this lesson but I have not yet come across the plural of a noun with a 'the' before it, and i'm curious as to how it would look.
It technically can, if you are referring to some sort of unknown alien entity devouring the horses. (Hopefully you'll never have to.)
However, we don't refer to animals as 'hva' in this setting, so we'd rather say:
Hvilke dyr spiser hester?
Which animals eat horses?
