The suffix -hedron originates from the Ancient Greek word hédra (ἕδρα), which means "seat," "base," or "face of a geometrical solid". It traces back to the Proto-Indo-European root *sed-, meaning "to sit".
In geometry, it is used as a combining form to denote a 3D solid figure with a specified number of flat faces. For example, a shape with four faces is a tetrahedron (from the Greek tetra, "four"), and a shape with twenty faces is an icosahedron.
-ist is a common noun-forming suffix used to denote a person who practices, specializes in, or adheres to a particular subject, profession, or doctrine. It typically signifies a doer, a follower, or an expert (e.g., artist, scientist, optimist).
The suffix originates from the Greek suffix -istēs (-ιστής). It was adopted into Latin as -ista. It entered Middle English through Old French as -iste, eventually evolving into the modern English -ist.
The Hedronist community formed in the early 2000's in Ashland, Oregon when a group of people with common interests in geometry, math and philosophy began meeting weekly to share their studies and projects, and discuss how these principles can be applied to construct a healthier, more beautiful, harmonious world.
