A sidewalk is a path made for pedestrians along the side of a road.
You've probably walked on one many times without even thinking about it - when you're going to school or work, or just out for a stroll. A sidewalk usually runs alongside streets and roads, providing a safe place for people to walk instead of having to step onto the street with traffic. It's often made of concrete, asphalt, or brick, and can be wide or narrow depending on where it is. Sometimes sidewalks are lined with trees or flowers, making them look nice as you pass by.
A footpath, usually paved, at the side of a road for the use of pedestrians; a pavement (UK) or footpath (Australia, New Zealand)
