What term describes something related to a social organization?

The term "fraternal" specifically refers to a sociological and organizational context, often used to describe organizations that are formed based on a bond of brotherhood or fellowship. These fraternal organizations commonly focus on mutual support, shared interests, and work within social networks, making them directly related to the concept of a social organization.

In contrast, community describes a group of people living in the same place or sharing characteristics, which is more about geographical or demographic connections. Societal encompasses a broader scope, dealing with aspects of society as a whole and its various structures. Collective typically refers to a group acting together, which may not necessarily imply a formal organization. Thus, fraternal most precisely captures the essence of a structured social organization.
