I see the sentence in my book : There will be an accident on his corner one day.
May you tell me what is the meaning of :’on his corner’?
It's not possible to say without further context, but the most likely interpretation (because it doesn't have a different explicit context in the one sentence) uses the following definition of corner:
[Merriam-Webster]
1 b : the place of intersection of two streets or roads
In other words:
There will be an accident on the street near where he lives (or works) one day.
Perhaps, for instance, it's a heavily trafficked intersection that doesn't have a traffic light.
