A more thorough explanation:

Definition: An estate held in fee simple absolute.

Explanation: Alodium is a type of land ownership where the owner has full ownership of the land without any feudal services or obligations. This means that the owner has complete control over the land and can use it as they wish.

Example: In the United States, owning a home or property without any mortgage or liens is an example of alodium. The owner has complete control over the property and is not obligated to pay any feudal services or obligations to anyone.

Another example: A farmer who owns a piece of land outright and does not have to pay any rent or taxes to a landlord is also an example of alodium. The farmer has complete control over the land and can use it for farming or any other purpose without any obligations to anyone else.
