Which term would best describe a link or connection between ideas?

The term "nexus" is most accurately used to describe a link or connection between ideas. In various contexts, "nexus" refers to a central point or connection that joins different elements or concepts together. It conveys the idea of an intersection or a relationship that binds, making it a fitting choice when discussing how different ideas relate to one another.

For example, in a discussion regarding the interrelationship between various theories or philosophies, referring to the "nexus" of these ideas emphasizes their interconnectedness or how they influence one another. This term captures the essence of connection effectively compared to the other options, which are not directly related to the concept of linking ideas.
