The word 'castle' refers to a big and tall building that was built long ago to protect people from enemies. Castles usually had walls, towers, and moats surrounding them to keep people safe. They were often used as homes for the king or queen and their family, as well as a place for soldiers to stay. Nowadays, some castles have been turned into museums and tourist attractions, where people can visit and learn about history. You can use the word 'castle' when talking about a building that looks like a castle or when you are talking about a real castle that you have visited or seen in pictures.
