"On chodzi."

Translation: He walks.

[YungBoi1]

Is there any way to tell when chodzi means walks vs goes? Or does it matter?

[Jellei]

"Goes" should imply some direction, so it rather cannot be a correct answer in such a short, vague sentence. But "on chodzi do szkoły" could be translated both as "he goes to school" and "he walks to school".

[imKyoshi]

Shouldn't "He is going" be accepted? Or I'm kinda lost here. CAPTAIN!

[Jellei]

To quickly answer:

chodzić = the Simple versions (to go, to walk)

iść = the Continous versions (to be going, to be walking)

To be walking without a purpose and direction can also be "chodzić".

To Marek: Is iść imperfective and chodzić perfective?

[Jellei]

They are both imperfective, they don't say anything about 'reaching the place'. They differ in aspect: habitual vs progressive (Simple vs Continous).

[Ann270528]

O co mu chodzi?

[Jellei]

For others: that's a common construction which means something like "What does he mean?", "What does he have in mind?", "What is he talking about?" and so on.
