Okay, so imagine you're walking down the street and you come to a corner where the road turns. That's called a street corner!
People usually hang out on street corners to talk to their friends, to wait for a bus or to watch cars drive by. Sometimes, people also sell things like fruits, flowers or newspapers on street corners.
It's important to be careful when you're on a street corner because cars might be turning and you don't want to get hit! So, always make sure to look both ways before crossing the street corner.
