EDIT: Also it felt like the whole game was written from an "Indo-European" perspective. For example, in Turkish there is a word "bir" (read [biɾ]) which literally means "one" which is sometimes used akin to indefinite articles (a/an). But they're not exactly indefinite articles, and sentence usually makes sense without them and when you speak fast you omit them. But in Duolingo they taught as if you should translate "the X" without "bir" and "a/an X" with "bir". That's not even remotely close to the truth (and made me get all "article" questions wrong). In Turkish definiteness is mostly denoted with accusative case. There is no single language construct similar to "article", you infer it from other kinds of information. For example "dolaba bira koy" : "put A beer in the fridge" vs "dolaba biraYI koy" : "put THE beer in the fridge". You add +I accusative suffix to "bira" (beer). This was not even mentioned in Duolingo. It also makes sense that they don't mention this sicne this is probably super advanced nuanced speaking, but then be consistent and don't teach that "bir" distinction to beginners as well.
