The word "bond" refers to a strong connection or relationship between two or more parties. This can be an emotional connection, such as the bond between family members or friends, or a legal or financial agreement, such as a bond between a borrower and a lender. In general, a bond signifies a tie or obligation that unites individuals or entities.
The word "bond" comes from the Old French "bond," meaning "a tie, a restriction," which in turn derives from the Latin "ligare," meaning "to bind." It has evolved to encompass various meanings related to connection and obligation over time.
