Thread: Verb of motion problem

The correct answer (in a test I took) is: Ты идёшь в университет сегодня?

I wrote: Ты ходишь в университет сегодня? on the grounds that you are going and coming back.

Why is this wrong? Is it to do with the present tense? I.e. we cannot use the multi-directional verb in the present for a single trip?

'ходишь' implies repetative process here. 'идёшь' implies continuous process. Difference is subtle, but it matters here. "Will you go to the univercity today?" vs "Are you visiting univercity (several times) today?". Such phrase is legal as is but it means different thing.

These verbs are called multidirectional (like "ходить", simple aspect) and unidirectional (like "идти", continuous aspect):
(1) "Ходишь в университет" - multidirectional (or, like you say, used to show a repeated action - simple aspect, in terms of English grammar);
(2) "Идёшь в университет" - unidirectional (or used to show a one-time/single action - continuous aspect). In this case, very similar to English "Are you going to university today?" (continuous aspect, as we know, shows an intended future action, not only the current one)
