Forms
ἀέναος (aénaos), adjective of two endings (-ος, -ον); adverb ἀενάως.[1][2][3] Ionic ἀένναος (aénnaos) (Herodotus), also αἰέναος (aiénaos) (Aeschylus, a Laconian inscription) and contracted Attic ἀείνως (aeínōs) (Aristophanes, Cratinus).[3][1][2]
Etymology
It is a compound from Ancient Greek αἰέν (aién, “always”) + νάω (náō, “to flow”), so properly “ever-flowing”.[2][1][4] Babiniotis takes the first part as an old locative of αἰών (aiṓn, “age, lifetime”) and a by-form of ἀεί (aeí, “always”), and starts from a form with a double ⟨νν⟩, the one Herodotus still writes.[4][3] The Etymologicum Magnum gives the same analysis: it derives the word from the verb “to flow” and glosses it “always flowing”.[5] Beekes finds no certain cognate of the verb νάω (náō) outside Greek.[6]
Earliest recorded meaning
Its first use is in Hesiod's Works and Days (595), of “an ever-flowing spring that runs off and is clear”.[3][1][4]
Semantic evolution
In archaic and classical poetry and prose it describes running water: rivers in Hesiod and Aeschylus, a lake in Herodotus, clouds in Aristophanes' Clouds, and even fire in Pindar.[1][3][2] In the Frogs Aristophanes uses the contracted form comically, of an “ever-flowing” stream of mud and dung in the underworld.[1][3]
From the start it was also figurative: Simonides and Heraclitus use it of everlasting glory, Pindar of the unfailing tables of public hospitality, Euripides of unending power and Xenophon of an inexhaustible supply of food.[1][3][2] Philosophers used it for what lasts for ever: Plato of being, and later writers of nature and of motion.[3]
In the Septuagint it renders the “everlasting hills” of Genesis and calls God eternal in Job; the Wisdom of Solomon keeps the literal “ever-flowing spring”.[7] The First Letter of Clement speaks of the everlasting order of the universe, and Hellenistic and Byzantine papyri and inscriptions call God “eternal”; in legal papyri the phrase “for the everlasting time” means in perpetuity.[8][3]
Modern Greek keeps it as the learned Modern Greek αέναος (aénaos), “perpetual, unceasing”, as in the perpetual cycle of life.[9][4]
