"There is a chair behind me."
From a contributor:
Unfortunately, we don't currently have the technical capability to include furigana. We (the contributors) would also be very happy if this capability was added by staff, but it's currently not available. I'm not one of Duo's staff/developers, so I don't know how much work and resources would have to be diverted in order to add this capability (or where this would exist on their priority list), so I can't speak to the likelihood of it being added in the future.
We also can't just use a workaround by putting the hiragana pronunciation in with the English hints, because then Japanese words in hiragana would appear in the word tiles when you are meant to compose a sentence in English. That would make the distractor tiles completely useless (since it's clear hiragana doesn't belong in an English sentence!).
We do hear your frustration, which has also been voiced by many other users in the past, but currently it's not within our power. Hopefully someday though!
Remembering the kanji is a good book to make it very difficult to forget kanji. That with anki and you now have your kanji forever with no subscription costs (anki is free everywhere but apple). I've learned 400 kanji this way so far and i can write them all. Eventually I'll learn the rest. There are 2200 in the first book. The downside is it doesn't teach readings.
2020.4.24 Learning to say the word first うしろ (for back) then learning it's written 後ろ, may help too.
With the okurigana ろ it has to be read うしろ and without it, it can be ご or あと. ご will most likely be a kanji compound like 午後「ご。ご、p.m.」or 放課後「ほう。か。ご、after school」or あと where probably it's not a kanji compound
it's both. Omitting the subjrct or topic is extremely common in japanese, whenever the context is clear enough. Duo tries to use the language as it would be used, so they omit topics frequently, and use "me" as an imaginary context so that there aren't 50+ right answers to every question.
the word order isn't very important here. Because of the use of particles (が and に in this sentence) to mark the grammatical function of words, it's understandable in almost any order, so long as the particles are paired up right. Order can change the emphasis of a sentence too.
Furthermore, in this case, there is an implicit subject (the speaker), so you could think of it as 「[僕の]後ろにいすがあります」. You are describing the object (a chair) in relation to the subject (the speaker). I think 「が」 is primarily used to describe the object, so you use 「が」 even when the subject is elided.
I think it's also because it is an exclusive description: i.e, the chair is not anywhere else but behind you: 後ろにあります. I think the English sentence in this example is a bit confusing because it is a more general statement that "there is a chair behind me" rather than "the chair is behind me", which seems like what the Japanese sentence is actually saying.
You would use は for inclusive descriptions, i.e. if you say that you're a member of the NRA, that doesn't mean you're not a member of some other charitable organization, therefore 「[SUBJECT]は[OBJECT]の会員です」. By that same token, even if a description is not generally exclusive, in some cases it can warrant a 「が」, and that can also come along with dropping some particles like 「の」in certain cases, it's tricky.
There are other subtle signals sent by the choice between 「は」 and 「が」, and you're honestly more likely to figure them out with listening experience than with hard and fast rules.
You've got the main idea, but there's one more element to it. あります (arimasu) can only be used with inanimate objects, so your second sentence means "(something) is behind the chair". If you want to say that you, a living person, are behind a chair, you need to replace あります with います (imasu).
Ok, thanks. I just read through some other comments, which I didn't earlier as there were so many and I was in the middle of practise on my phone. Someone else advised that it can be in either order so long as the particles are correct. To confirm them are you saying that although it can use GA or WA in either order, it is more commonly used for GA at the end and WA at the start?
Also isn't GA used for emphasis so that would be when we are talking about a chair, chairs in general already? E.g. The chair is behind me would be for GA rather than WA, right?
ます (masu) is just the helper verb ending the word, it's not actually a word used by itself, so you needed the stem of the verb to complete your answer.
The answer that it tells you is "right" is often the version of the answer that you came closest to (there is more than one right answer). The preferred answer at the top of this thread is 後にいすがあります (ushiro ni isu ga arimasu). ある (aru) is the short form of あります (arimasu). I'm guessing there was probably a floating あり (ari) somewhere in your options.
