Questions & Answers about Утром я иногда хожу в бассейн.
Why do we use хожу instead of иду in this sentence?
The key here is the word иногда (sometimes). Because going to the pool is a repeated or habitual action, we use the multidirectional verb ходить (its 'I' form is хожу). We only use идти (иду) when we are talking about a single trip happening right now in one direction.
Would it be wrong to say езжу instead of хожу?
It wouldn't be grammatically wrong, but it would change the meaning! Ходить (хожу) means going on foot, while ездить (езжу) means going by transport. By using хожу, the speaker is telling us they usually walk to the pool.
Why does the word for morning (утро) end in -м here (утром)?
To say 'in the morning' in Russian, you take the noun утро and put it in the Instrumental case, which gives it that -м ending: утром. You do this with other times of day too, like вечером (in the evening) or днём (in the afternoon).
I see в for 'to'. Why doesn't the word бассейн change its ending?
