"Ini" means "this", not "the".
I've noticed that Duolingo has taken certain liberties in translating, which makes it difficult to learn the language.
It certainly helps studying but I am missing introductions into the material, explanations and insights. Like with the paid app Babbel. Also not perfect but atleast they explain the context. What I do like about Duolingo is the community, helping each other.
But hey.. it's in Beta.. ;-)
