Pronunciation
Forms
ἠώς (ēṓs) f (genitive ἠόος or ἠοῦς); third declension[1] Attic ἕως (genitive and accusative ἕω), Doric ἀώς and ἀϝώς, also ἀϝώρ, Aeolic αὔως.[2][3] Hesychius records a Boeotian ἄας, glossed “till tomorrow”.[3] The Homeric locative is ἠῶθι, in the phrase ἠῶθι πρό “early in the morning”.[3][2]
Etymology
It is inherited from Proto-Hellenic *auhṓs,[1] inherited from Proto-Indo-European *h₂éwsōs (“dawn”), the Indo-European word for the dawn, which was also worshipped as a goddess.[1][2] Beekes reconstructs Proto-Greek *ausṓs, which matches Latin aurōra (“dawn”) exactly except for the Latin ending; Sanskrit उषस् (uṣás, “dawn”) has the zero grade of the root.[2][4] An *r-stem of the same root is seen in αὔριον (aúrion, “tomorrow”), Lithuanian aušrà (“dawn”) and Old High German ōstara (“Easter”).[2]
Chantraine derives all the dialect forms from a stem with intervocalic /s/, which was lost.[5] Attic ἕως (héōs) owes its initial aspiration to the lost /s/, according to Chantraine, or to a metathesis of aspiration, according to Beekes and Frisk; its accent on the first syllable was probably taken from the adverb ἕωθεν (héōthen), where it is regular.[5][2][4]
Earliest recorded meaning
The word is common in Homer, both for the dawn and the daylight it spreads and for the goddess Dawn, “rosy-fingered” and “early-born”.[6][3] In the Iliad it also counts days, as in “the twelfth dawn”, and names the east, “towards dawn and the sun”.[6][3]
Semantic evolution
Homer already used the word in several senses: the daybreak, the morning as a stretch of time (the accusative meaning “all morning long”), a day counted as one of a series, and the quarter of the sky where the sun rises.[6][3] The Ionic form is the Homeric and Herodotean one, while Attic prose used ἕως, in phrases such as “at daybreak” and “towards the east” in Thucydides and Xenophon.[3][5] Late poets also used it for “life”, the light of day that the dead leave behind.[3]
Derivatives kept the sense of morning: ἠοῖος (ēoîos) “of the dawn, eastern”, ἕωλος (héōlos) “a night old, stale” (of food), and the compound ἑωσφόρος (heōsphóros) “bringer of dawn”, the morning star.[2][5]
The word for “dawn” disappeared from spoken Greek, but έωλος (éolos) and εωσφόρος (eosfóros) survive.[5] Babiniotis still lists Modern Greek ηώς (iós), from the ancient Epic and Ionic form.[7]
