Which term can describe a connection or series of connections linking two or more things?

The term "nexus" effectively captures the idea of a connection or series of connections linking two or more things. It emphasizes the central point or focal connection between elements, suggesting a more complex relationship rather than just a physical link. "Nexus" is often used in various contexts, such as in discussions of ideas, themes, or systems, where it denotes an intricate network of relationships. This term encapsulates not only the connections themselves but also the significance of those connections in bringing different entities together.

While "network" could also denote connections, it typically refers to a system of interconnected elements and lacks the nuance of a central or pivotal connection that "nexus" provides. "Chain" implies a linear sequence of links, which may not adequately represent the complexity of multiple interconnected relationships. "Bridge" suggests a physical or metaphorical structure that connects two separate points, but it doesn’t convey the broader or more intricate connectivity implied by "nexus." This makes "nexus" the superior choice in describing a connection or series of connections linking two or more things.
