  • 10th-century Byzantine: /ka.ta.klyzˈmos/[1]

Forms

κᾰτᾰκλῠσμός (kataklusmós) m (genitive κᾰτᾰκλῠσμοῦ); second declension[1]

Etymology

It is from Ancient Greek κατακλύζω (kataklúzō, “to wash away, deluge”) with the suffix -μός (-mós), the verb being κατα- (kata-, “down”) and κλύζω (klúzō, “to wash”).[1][2][3] Κλύζω comes from Proto-Indo-European *ḱlewH- (“to wash, clean”).[1][4] Cognate with Latin cluō (“to clean”), Gothic 𐌷𐌻𐌿𐍄𐍂𐍃 (hlūtrs, “pure”), Welsh clir (“clear, pure”) and probably Lithuanian šlúoti (“to sweep”).[1][4]

Earliest recorded meaning

Plato is the first to use it, in the Timaeus and Critias for the great floods that periodically destroy mankind, and in the Laws.[5][6][7]

Semantic evolution

In Plato and Aristotle it is a flood or deluge, and Plato uses it figuratively of diseases sweeping through a city, and Demosthenes of a political “deluge” that washes events away.[6][7][2] The Parian Marble uses it of Deucalion's flood, and a papyrus of the 3rd century BC of an ordinary inundation.[8][6] The Septuagint chose it for Noah's flood in Genesis, and the New Testament uses it only of that flood.[9][8] Coptic borrowed it.[10]

English cataclysm (1630s), first of Noah's flood, came through French cataclysme, from Latin or directly from Greek.[11] Vernacular medieval Greek kept the word for a flood of water, and the learned Modern Greek κατακλυσμός (kataklysmós) continues it.[12][13]
