What term refers to a connection or bond between entities?

The term "nexus" is particularly suitable in describing a connection or bond between entities because it specifically denotes a central point or a significant connection that links various elements together. In many contexts, “nexus” implies a relationship that is not just superficial but rather integral to the nature of the entities involved. This term conveys a sense of interdependence and interaction that goes beyond mere association, suggesting a deeper or more complex relationship.

Consider that while "linkage" might also suggest a connection, it often refers to a more technical or mechanical association rather than a conceptual or relational one. "Union" indicates a joining together but may not encompass the nuances of connections between multiple entities. "Division," as the term implies, refers to separation or disconnection, which makes it contrary to the idea of establishing a bond or connection. Thus, "nexus" effectively captures the essence of interconnectedness among entities, making it the most fitting choice.
