That's interesting, I haven't thought of it that way. How I remember it is, besto=best friend, an animal can be a person's best friend. Similar to, "a dog is a man's best friend." It may sound complicated, but it works for me haha.
is it me or is the esperanto course less forgiving for typos? i'm very bad at typing so i wrote "the animal drinks watwe" which is a very simple typo, but i was marked incorrect
It could be just you, but maybe not. My sense, though, is that typo forgiveness is not something that the individual courses have control over. It's part of the behind-the-scenes workings of the Duolingo system, so I would expect it to be equally forgiving in all courses. I also know that the course authors occasionally add common typos as correct answers to reduce frustration.
