A more thorough explanation:

Definition: Liberum servitium (lib-uh-rum sur-vish-ee-um) is a Latin term used in law. It refers to the service provided by a free tenant to their lord, which could include attending the lord's court or joining them in military service. This service was provided by a free tenant, not a vassal.

Example: In medieval times, a free tenant might provide liberum servitium to their lord by attending court sessions and helping with military campaigns. This service was a way for the tenant to show loyalty to their lord and maintain their status as a free person.

Explanation: The example illustrates how a free tenant might provide liberum servitium to their lord. By attending court sessions and joining in military campaigns, the tenant was fulfilling their obligation to their lord and showing their loyalty. This service was important for maintaining the relationship between the lord and tenant, and for ensuring the tenant's status as a free person.
