"В школе" = "at school" (with "школа" in prepositional case, indicating a fixed location), while "в школу" = "to school" (with "школа" in accusative case, here indicating a destination).
So “Yes, he goes to the school” is wrong? Why is the “the” making it wrong?
My guess would be because there's a difference between walking to the school at this very moment and going to school in general.
In this case, the verb "Go" is used in more general sense. That's way we should use the verb Ходить, not идти
NOTE: You can always check tips for more information
What is the difference between the two verbs? To go and to go by walking?
Is this actually wrong? What is we wanted to indeed say more specifically he is going to school right now, and not in sort of an ongoing habitual way. Could we then use "да, он идет в школу"?
If you mean the conjugation, then no. It's not conjugated that way. This is the proper conjugation.
In this fall, I am going to begin in eight grade (in high school). How would you say ‘I’m in eight grade’? Что лучше, «Я в восьмом классе», «Я хожу в восьмном классе» или «Я хожу в восьмной класс»?
If you’re wondering about the ‘going in’-construction used with ‘grade’, I’m just applying Swedish and German knowledge to Russian, we’ll see how that turns out. ☺
I wrote down the right sentence "da on xodit v shkolu" but it was not considered as correct. Do you know why?
Maybe it's because of the 'xodit' which might be pronounced as 'ksodit' and not 'khodit'
It's explained in the Tips and Notes of the section.
он идёт в школу. = He's going to school (right now).
он ходит в школу. = He goes to school (he attends a school).
So идти is "one-directional" (going right now), and ходить is "two-directional" (going generally, habitually).
See my comment on cerez00.
If you want to say that he is currently walking to the school, "идти" looks like a better fit for your sentence, so I guess you could translate that as "он идёт в школу (пешком)".
If you say he generally walks to school, I would add пешком to make it clear that it's about going on foot, and not just about going there in general, so maybe "он ходит в школу пешком".
Btw, there are some nice example sentences with these "go"-verbs here.
I answered "Yes, he walks to school" and I get it right. Maybe it's not correct to put a definite article before the word school.
I thought the correct pronunciation was шкОлу, not шкОлУ. She's pronouncing unstressed О as [О ] rather than [А] which IIRC is not really "correct". Can someone confirm this?
