Etymology: Archegonium is a botanical term for the flask-shaped female reproductive organ found in mosses, liverworts, ferns and conifers. It is built from two Greek elements: "archē," meaning beginning or origin, and "gonos," meaning offspring or birth, with the Latinised suffix "-ium" added to make a technical noun. The word is a scientific coinage, so the ancient Greeks had no such term; the combination describes the organ's role as the place where the first cell of a new generation begins to develop. The "arche-" element is the same one found in words like "archetype" and "archive," where it carries the sense of a first or original form. Its partner "-gon" is also seen in "-gony" words such as "cosmogony," the study of how the universe originated. Put together, the components describe something like "origin of offspring," which fits the organ's function closely.
