2. This geometric figure consists of ten thousand straight edges and corners
3. In mathematics, it refers to a shape characterized by having ten thousand sides

Etymology: A myriagon is a polygon with ten thousand sides, a shape so complex that it defies easy visualization. The word entered English in the 19th century, arising from a period when mathematical terminology was expanding to describe increasingly intricate geometric forms. Its precise formation reflects the classical tradition of using Greek numerical prefixes combined with the suffix "-gon," meaning "angle" or "corner," to name polygons by their number of sides. The prefix "myria-" derives from the Ancient Greek "myrios," meaning "countless" or "ten thousand." This term originally conveyed an almost boundless quantity rather than a strict numeral, akin to the English "myriad." By attaching the Greek "-gon" (from "gonia," meaning "angle"), the term literally translates as "ten-thousand-angled," a fitting description for a shape with so many vertices. While polygons with a handful of sides—triangles, pentagons, decagons—are easily drawn and studied, the myriagon exists mostly as a theoretical construct. The word captures the human desire to name and conceptualize even the most abstract mathematical shapes, reflecting the influence of classical languages on scientific nomenclature. Its introduction marked a time when mathematics increasingly borrowed from Greek to provide precise, systematic names for complex figures. The term also highlights an interesting facet of language: how numbers and shapes combine in technical vocabulary to create words that are both descriptive and efficient. Unlike everyday polygons, the myriagon's name is rarely encountered outside specialized mathematical texts, yet it carries the weight of millennia of linguistic tradition, linking modern geometry to ancient Greek roots.
