Public means something that is available or accessible to everyone in the community. Imagine a big playground where you and all your friends can play together. That playground is public because everyone can come and play there anytime. Public things are usually paid for by the government, like public schools and libraries. Public things are also important for people to use and enjoy together, like parks and museums. Sometimes private things can become public, like when someone shares a secret with a group of people, it becomes public knowledge. Overall, public things belong to everyone and can be used by everyone.
