A sidewalk is a pathway that people walk on beside the road. It looks like a gray or beige strip made of concrete with little lines on it. It's like a walking path that is only for people, and not for cars or bikes. You walk on it to get from one place to another, like from your house to the park or from the bus stop to school. It's important to walk on the sidewalk so you don't get hit by a car or have to walk on the street, where it's not safe. Remember to walk on the right side of the sidewalk, just like how you would drive a car, so you don't bump into anyone coming the other way.
