Why “antediluvianism” is a great word
ANTEDILUVIANISM — [Noun] The condition or quality of being extremely antiquated or belonging to a time before the biblical Flood. From antediluvian (from Latin ante- "before" + diluvium "flood") + -ism (suffix forming nouns of action, state, or doctrine). Unlike archaism, which denotes a specific outdated word or style, or obsoleteness, which indicates a simple lapse from current use, antediluvianism describes a profound, sweeping outdatedness. It is the dust-laden policy manual unrevised for fifty years, the rusted gears of a forgotten machine, and the worldview preserved in amber while continents of thought have drifted—a stubborn, ghostly faith in a world officially washed away.
