What is non-passable?

"Non-passable" means something that cannot be passed through or over. It implies an obstacle or barrier that prevents movement or passage. Here are some examples:

* A road blocked by a landslide is non-passable.

* A thick forest with no paths is non-passable.

* A locked door is non-passable.

* A very narrow bridge that cannot accommodate vehicles is non-passable.

It's important to note that "non-passable" is often used in a physical sense, but it can also be applied metaphorically. For example, you might say that a bureaucratic process is "non-passable" if it's overly complicated and difficult to navigate.
