Questions & Answers about Я иду мимо дома.

What is the difference between я иду and я хожу?

Both come from verbs of motion meaning to go / to walk, but they are used differently:

• я иду – one‑way, right now, on foot.

  • Focus on a single movement in one direction, typically happening at this moment.
  • Roughly: I am going / I am walking (now) in one direction.

• я хожу – habitual, repeated, or multi‑directional motion on foot.

  • Used for habits, regular routes, or movement there and back.
  • Roughly: I go / I walk (regularly / in general).

In Я иду мимо дома, the speaker is describing what is happening at this moment, in one direction, on foot, so иду is the natural choice.

Why is it мимо дома and not мимо дом?

Because мимо is a preposition that always requires the genitive case.

• The noun дом (house) in the genitive singular is дома.
• So the pattern is: мимо + genitive → мимо дома (past the house).

Other examples:

• мимо школы – past the school (школа → школы, genitive)
• мимо магазина – past the shop (магазин → магазина, genitive)

Using мимо дом would be grammatically wrong, just like saying past he house in English.
