A more thorough explanation:

Definition: A type of fee that is restricted to the owner's descendants or a specific class of descendants, rather than being passed down to all heirs.

Example: If a landowner creates an entail on their property, they may specify that it can only be inherited by their children or grandchildren, rather than any distant relatives.

This means that the property will stay within the family line and cannot be sold or transferred to anyone outside of the specified group of descendants.

Overall, an entail is a legal way to limit the inheritance of property to a specific group of people, rather than allowing it to be passed down to anyone who may be distantly related to the owner.
