A playground is a place to frolic and play. Most kids know where the nearest playground is because that’s where the swings and slides are. Neighborhoods and schools usually have a playground. Weeeeee!
A playground built especially for kids has equipment for them to play on, like climbing structures, swings, seesaws, and play houses. Many public parks have this kind of playground. When adults talk about their favorite playgrounds, they usually mean a place they go to do the sports or activities they love. A nearby mountain, for example, could be described as a playground for snow boarders.
