Etymology: The word was coined in the 19th century, not in antiquity, and it is built from two Greek elements: "archē", meaning "beginning" or "origin", and "gonos", meaning "offspring" or "generation". Plant anatomists assembled these pieces to name the flask-shaped organ in mosses, liverworts, ferns and conifers that holds the egg cell. Its literal sense is something like "beginning of generation", a fitting name for the place where new life starts. The term is a plural form, as the "-a" ending shows: the singular is "archegonium", and the plural follows the Greek neuter pattern. The singular itself is a modern scientific Latinization of the Greek compound, so the word belongs to the same family of botanical coinages that describes other plant reproductive parts, such as "antheridium" for the pollen-producing organ.
