Questions & Answers about Z samej góry widać jezioro i las.
Widać is an impersonal Polish form meaning you can see, one can see, or ... is visible.
So:
- Widać jezioro i las = You can see a lake and a forest
- more literally = A lake and a forest are visible
It is very common in Polish when the speaker wants to describe what is visible from a place, without saying exactly who is looking.
Because widać does not need one. It is impersonal.
English often uses a general you in sentences like this:
- From the top, you can see the lake
But Polish often avoids that kind of general you and simply uses widać. It sounds natural and objective, more like describing the view itself rather than the person viewing it.
