Free as is "free beer," haha. Great example.
It's easy to associate kostenlos with no cost because, well, that's what it sounds like. Took me a while to understand all the meanings of frei though (not that I probably understand it completely yet anyway).
theres free beer in Germany?
course there is, i mean, they have so much of it, why not just give some away?
Der Vogel ist frei = The bird is free (means: it is not in the cage, free to fly)
kostenlos = costless frei = free (freedom) If you're friend is giving you a bird, it's kostenlos. If he's freeing him out of his cage, the bird's frei.
Kostenlos, if you look carefuly, is costless (wrong answer....tough), but means cost-free, wich is the same thing. frei would be more boundless...
Why 'costless' is a wrong answer yet 'cost-free' is? I've never heard of cost-free...
Duolingo evolves with time. When we find right answers that are not accepted, we report it, and soon they answer telling that option is now accepted.
I live in Zurich and i listen "gratis" very often..can it be used as well?
I thought "kostenlos" meant "complimentary," but Duolingo said that that's a wrong answer.
