Etymology: Oogonium is a scientific coinage built from two Greek-derived parts. The first, "oo-", comes from Greek "ōon", meaning "egg", and the second, "-gonium", comes from Greek "gonos", meaning "offspring" or "seed", with the "-ium" ending as used in biological terms for a structure or organ. Put together, the name describes an organ or cell that produces eggs, which is exactly what it is: the female reproductive cell in organisms such as algae, fungi and some protists. The word was made by biologists for a technical purpose, not inherited from the ancient Greeks, who had no concept of a single microscopic egg-producing cell. Its meaning stays close to its parts: the "egg-producing" element is kept in the first half of the word, and the second half supplies the sense of generation.
