One translated from Norwegian:
“Once upon a time… But now it’s a corridor”
I’ll supply the original and an explanation:
“Det var en gang… Men nå er det en korridor”
“Det var en gang” is literally “It was a time/an instance”, and it’s the main way every fairytale starts in Norwegian. But “gang” could also mean hallway.
Norwegian as well. It’s basically impossible to find the documentation. Translation has somehow changed the order of words, som direct translation of formulaes is not helpful for searches either.
