'''Nausea''' derives from [[Latin]] and is the plural of ''nauseum''. It has the same root as natation, the sense or act of [[swim]]ming. The singular form of the word appears in English in phrases such as: "He talked about life insurance ''ad nauseam''", implying the speaker has said more than the listener wants to hear. Since nausea is already plural, it is not correct to write ''nauseas'', for the same reason it is not correct to write ''datas'', ''medias'', or ''magmas''.
