Definition of mutual

The word "mutual" originates from the Old French word "mun" meaning "son" or "offspring." During the Middle Ages, when feudalism was prevalent, the lord's property was considered to be held in trust for his vassals, or tenants. The vassals, in turn, pledged their loyalty and military support to their lord. The relationship between the lord and vassal was originally called "munus," which emphasized the loyalties and obligations between the two parties. However, over time, this term evolved into "mutueulite" or "mutualite" in French, emphasizing the idea of reciprocal obligations between two equal parties. The concept of mutualism expanded beyond feudalism to encompass various relationships, such as marriages, business partnerships, and insurance associations. In insurance, mutual societies emerged in the early 18th century in which policyholders were also owners or members of the company. The term "mutual" then came to signify the idea that the members of a society or company would hold and manage it jointly as a mutual association. Today, the word "mutual" is commonly used in various aspects of society, such as mutual funds, mutual communication networks, mutual clubs, and so on, signifying an association in which all parties share in some mutual benefit, obligation, or responsibility.
