Questions & Answers about Nie idź przez środek ulicy.
Idź is the imperative form of iść.
- iść = to go / to walk in one direction
- idź! = go!
- nie idź! = don’t go!
In this sentence, idź is addressed to one person in an informal way.
Related forms:
- idźcie = imperative for more than one person
- formal singular commands are usually expressed differently, for example:
- Proszę nie iść przez środek ulicy.
- Niech pan/pani nie idzie przez środek ulicy.
Because iść and chodzić are not the same.
- iść = to go/walk in one specific direction, on one occasion
- chodzić = to go/walk habitually, repeatedly, or in no fixed direction
This sentence warns someone about a specific movement, so iść → idź is the natural choice.
Compare:

Also, chodź! very often means come on! / come!, so it would not fit well here.
