Forms
ἕως (héōs) f (genitive ἕω); second declension[1] Ionic and epic ἠώς (ēṓs), Doric ἀϝώς, ἀϝώρ, Aeolic αὔως.[2][3]
Etymology
The dawn is inherited from Proto-Hellenic *auhṓs, inherited from Proto-Indo-European *h₂éwsōs (“dawn”), and is the Attic form of ἠώς (ēṓs).[1][2][3] Its rough breathing is probably due to a shift of aspiration, as in εὕω (heúō), though Sommer took it from ἑσπέρα (hespérā); its accent on the first syllable was probably taken from the common adverb ἕωθεν (héōthen), where it is regular.[2][4][5] The Attic genitive and accusative ἕω follow the masculine nouns in ⟨-ως⟩ such as λεώς (leṓs).[5]
It is cognate with Latin aurōra, which adds a final ⟨-a⟩, and with the zero-grade Sanskrit उषस् (uṣás, “dawn”).[2][4][1] An r-stem of the same root is seen in αὔριον (aúrion, “tomorrow”) and Lithuanian aušrà (“dawn”).[2][4]
Earliest recorded meaning
The Attic form is found in tragedy: Aeschylus quotes a proverb, “may dawn be born from its mother night as a bringer of good news” (Agamemnon 256), and Sophocles has πρὸς πρώτην ἕω (pròs prṓtēn héō, “towards the first dawn”, Oedipus at Colonus 477).[6][3][7]
Semantic evolution
Attic prose uses it of the time of day: ἅμα τῇ ἕῳ (háma têi héōi, “at dawn”) and πρὸ τῆς ἕω (prò tês héō, “before dawn”) in Thucydides, and “the next morning” in Xenophon.[3][6] Like the epic word, it can also mean the east, where the sun rises.[7][8] Its derivatives ἕωλος (héōlos) “a night old”, of food, and ἑωθινός (heōthinós) “of the morning” are Attic and Ionic.[2] The lexicographers gloss it as the hour before sunrise, as daybreak, and as the day itself.[9][10][11]
Timeline
- Homer – The Iliad has the compound ἑωσφόρος (heōsphóros) “bringer of dawn, morning star”, perhaps an Attic touch in the epic.[2]
- 6th–5th century BC – Aeschylus quotes a proverb about the dawn born of night.[6][7]
- 5th century BC – Sophocles and Thucydides use the Attic form, and Thucydides has “at dawn” and “before dawn”.[3][6]
- 5th–4th century BC – Plato speaks of the time from one dawn to the next.[6]
- 5th century AD (probably) – Hesychius glosses it as the hour before sunrise, as daybreak and as day.[9][12]

Pronunciation
Forms
ἕως (héōs); epic ἧος (hêos), also written εἵως, Aeolic ἆος, Doric ἇς (hâs).[2][3]
Etymology
The conjunction is inherited from Proto-Indo-European *yéh₂wot (“as long as, until”), the relative adverb that is also continued by Sanskrit यावत् (yā́vat, “as long as, as far as”).[2][1][4] The final ⟨-ς⟩ is unclear: Beekes takes it as the adverbial ⟨-ς⟩ that Greek added, though not always in Doric.[2][4] The word belongs with the relative pronoun ὅς (hós), and its demonstrative counterpart is τέως (téōs, “so long, meanwhile”).[2][4][14]
Earliest recorded meaning
Homer has it, mostly as epic ἧος, for “until” with the indicative of a past fact (Il. 11.342), with κε and the subjunctive of an uncertain future, as in “I will fight until I find the end of the war” (Il. 3.291), with the optative after a past tense (Od. 5.386), and for “while” (Od. 13.315).[3][15] Homer also uses it as a demonstrative, “for a time”.[2][4]
Semantic evolution
With the subjunctive or optative it could also express purpose, “so that”, in the Odyssey and in papyri.[3] Classical Greek used ἕως ἄν with the subjunctive for “until”; tragedy sometimes leaves out ἄν, which becomes frequent in later Greek.[3] Hellenistic Greek made it a preposition with the genitive, rarely the accusative, “until” and “as far as”, of time, place and number, common in the Septuagint, the papyri and the New Testament, and it was combined with adverbs and relatives: ἕως οὗ and ἕως ὅτου “until”, ἕως πότε; “how long?”, ἕως ὧδε “as far as here”.[3][2][16] Babiniotis notes that it began to be confused with ὡς (hōs) already in antiquity.[17]
Medieval vernacular Greek used it as a conjunction and a preposition, also in shortened forms.[18] Modern Greek έως (éos) is a learned word.[19]

- 4th century BC – Aristotle uses it as a preposition of place, “up to the point where”.[3]

The Etymologicum Magnum derived the dawn from εὕω, explained as “to give light”.[20] The Antiatticist notes that Demosthenes uses the conjunction with the indicative, the optative, and the subjunctive with ἄν.[10]
