Demesne

Sure thing! Demesne is a fancy word that means the land or property a lord or ruler owned back in olden times. Think of it like a big backyard that the king or queen owned. They could use it to grow food or build things, and they could also let other people use it too, as long as they followed the king or queen's rules. The demesne was really important because it showed how rich and powerful the king or queen was, and it helped them control their kingdom.
