A more thorough explanation:

Term: Beneficium
Definition: Beneficium is a Latin word that means "benefit." It has several historical meanings:
1. In Roman law, it refers to a privilege, remedy, or benefit granted by law. For example, the beneficium abstinendi allowed an heir to refuse an inheritance and avoid the accompanying debt.
2. In medieval times, it referred to a lease given by a ruler or lord to a freeman. This lease was generally for life.
3. In English law, it referred to an estate in land granted by the king or a lord in exchange for services. Originally, it could not be passed to the holder's heirs, but over time it became a heritable estate.
4. In ecclesiastical law, it referred to a feudal tenure for life in church-owned land, especially land held by a layperson.
5. It can also refer to any particular privilege or favor, such as the benefit of clergy.
Examples:
- The beneficium abstinendi allowed heirs to avoid inheriting debt.
- A lord might grant a beneficium to a freeman, allowing him to lease land for life.
- In exchange for services, a king might grant a beneficium, which eventually became a heritable estate.
- A layperson might hold a beneficium in church-owned land.
- Benefit of clergy was a specific beneficium granted to members of the clergy, allowing them to be tried in ecclesiastical courts instead of secular ones.
