Etymology

The term entered English by way of the French cataclysme, which descends from the Latin cataclysmus. The root is the Ancient Greek κατακλυσμός (kataklusmós), meaning a deluge or flood, derived from the verb κατακλύζω (kataklúzō), to dash over or inundate. This is a compound of κατά (katá), signifying downwards or towards, and κλύζω (klúzō), to wash off or wash away. The imagery is one of water descending with sufficient force to ensure nothing remains where it was previously situated.
