Etymology

It is probably from ⟨*χάϝος⟩, beside χαῦνος (khaûnos, “loose, porous”), in the same relation as ἔρεβος (érebos) to ἐρεμνός (eremnós).[2][3][1] Its first meaning would then have been “hole, empty space, yawning opening”, and it has long been connected with χάσκω (kháskō, “to gape”), χάσμα (khásma, “chasm”) and χήμη (khḗmē).[2][1] Wiktionary takes the root to be Proto-Indo-European *gʰeh₂- (“to yawn, gape”), also seen in Germanic and Baltic words for the palate such as Old High German guomo and Lithuanian gomurỹs.[1][2] Frisk stressed that we do not know what Hesiod imagined by the word, which limits any etymology.[3]

Ancient writers derived it from χέω (khéō, “to pour”), as Zeno the Stoic did, who took the first element to be water, or from a verb “to give way, contain”.[4][5]

Earliest recorded meaning

Hesiod's Theogony begins its account of the world: “first of all Chaos came to be, and then broad-breasted Earth”.[5][6] The first thing to exist was later usually taken, from Aristotle on, to be empty space.[2][3]

Semantic evolution

Ibycus, Bacchylides and Aristophanes use it for the empty expanse of air where birds fly.[6][5] Philosophers saw in it infinite space, as Sextus and Plotinus, or unformed matter, as Lucian; for the Stoics it was water.[5] Later it was the nether abyss and infinite darkness, joined with Erebus, and Apollonius of Rhodes used it for the black of a starless night.[5][6] The Septuagint uses it for a gaping chasm.[7][5]

Latin borrowed it as chaos, and the Vulgate's use for the formless state of the world before creation led to the sense “utter confusion” in English about 1600.[1][8] Dutch gas was formed from it.[1] Modern Greek χάος (cháos) is a learned word for the primordial chaos, for space, and, after French, for disorder.[9][4]
