"du er ikke alene"
I misinterpreted this as "Dere er alle alene."
Aleine? Another spelling of alone?
Yes, but since we don't teach it, I've taken it out of "best translations."
Why is "helt" in the neuter here?
It's an adverb, so not the neuter version of the adjective (even if identical).
Could it also be "hel" alene?
No, as "helt" is functioning as an adverb in this sentence.
Takk, og god helg;)
Takk det samme! :)
Alle mennesker er alene
