In the image, "Diversity of Thought" and "Diversity of Identity" are two complex vectors passing through a general "Diversity Space". We know from bio-social studies that each of these vectors are influenced by many factors and can be defined many ways. Ultimately all forms of diversity are manifested in a unique, embodied individual - an insight shared between Intersectionality and Liberalism (Individualism).
"Uni-versity" is the organizational structure that aims to prepare the naive, educate the ignorant, and research the barely-known. There is only one University - otherwise they would have called it something different.
"Di-versity" is the idea that differences exist among groups of objects that are similar enough to call a group, but dissimilar enough where differences can be seen. The "Di-" prefix reminds us that defining differences is always an act of bifurcation. The sooner we can realize that ideas and definitions exist as a consequence of opposition to one another, a more productive political discussion might emerge.
"Tri-versity" is a made-up word (aren't they all....), and seemed like the next logical step in the sequence. Perhaps a "tri-versity" is the group of people who are "tri-ing" to make things "better" (implying coordinated action that also includes a collective consensus on what "better" should be).
