"Surat ini tidak jelas."

Translation: This letter is not clear.

"This letter is unclear." Would this not also make sense? It certainly feels more natural than "not clear". However, is it just a literal translation thing?

"The letter is not clear" is not accepted...…. I know it's beta but it's sometimes excruciating

[MasJem]

"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.. ;-)
