Etymology: Superfecundation is a plural noun form of a word built in English from two parts: the prefix "super-", meaning "over" or "beyond", and "fecundation", the act of making fertile. "Fecundation" itself comes down through Old French and Middle English from the Latin "fecundare", to make fruitful, and the "-ation" ending marks the process or act. Put together, the word describes a fertilisation that goes beyond the ordinary. The "superfecundations" in question are plural because the word names a biological event that can happen many times across a population, not a single one-off process. The term is a technical coinage, assembled from familiar English building blocks rather than handed down from classical sources, so its meaning is transparent: an event in which more than one fertilisation occurs in a single reproductive cycle.
