A more thorough explanation:

Definition: Fructuarius (pronounced fr-uhk-choo-air-ee-uhs) is a Latin term that means "one entitled to fruits." In Roman and civil law, it refers to a person who has the right to use and enjoy the fruits of a property, such as land or animals. This person is known as a usufructuary. In history, it also refers to a lessee.

• A farmer who rents a piece of land and has the right to use and enjoy the crops grown on it is a fructuarius.
• A person who leases a house and has the right to use and enjoy the property during the lease period is also a fructuarius.

These examples illustrate how a fructuarius is someone who has the right to use and enjoy the fruits of a property, whether it is crops grown on a piece of land or a house that is being rented. They have the right to use and enjoy the property, but they do not own it.
