A more thorough explanation:

Definition: Commune vinculum is a Latin term that means "common bond." In history, it refers to a relationship or tie between people, such as the bond between a lord and tenant or the relationship between blood relatives.

• A lord and tenant have a commune vinculum because the lord provides land and protection to the tenant in exchange for rent and loyalty.
• Family members have a commune vinculum because they share a common ancestry and often have emotional ties and obligations to each other.

These examples illustrate how commune vinculum refers to a connection or bond between people. In both cases, there is a mutual exchange of goods or services that creates a relationship of dependence and obligation. This relationship is often based on a shared history or ancestry, which further strengthens the bond between the parties.
