ἔσω,

ἔσω, used by Epic dialect, Lyric poetry, and Trag. Poets accusative as a spondee or iambus is required; ἔσω (as ἐς for εἰς) prevailed in Ionic dialect and old Attic dialect Prose; but in other Prose and in Comedy texts ἔσω was the only form admitted, whereas ἔσωθεν with the comparative and superlative ἐσώτερος, ἐσώτατος, ἐσωτέρω, ἐσωτάτω, seem to have been the only forms in use:— adverb of εἰς, ἐς, to within, into: absolutely, μή πού τις ἐπαγγείιῃσι καὶ ἔσω lest some one may carry the news into the house, [ἔσω 8th c.BC: Odyssea Homerus Epicus “Odyssey” 3.427 ">Refs 8th c.BC+]; also ἔσω δ᾽ ἀσπίδ᾽ ἔαξε he brake it through to the inside, [ἔσω ἔθλασεν 8th c.BC: Odyssea Homerus Epicus “Odyssey” 18.96; ἔσω ἐπιγράψαι τέρενα χρόα 8th c.BC: Ilias Homerus Epicus “Illiad” 13.553; ἐσσύμενοι ἔσω 5th c.BC: Pindarus Lyricus “P.” 4.135; ἔσω κομίζου 4th-5th c.BC: Aeschylus Tragicus “Agamemnon” 1035 ">Refs 8th c.BC+]; πέπληγμαι..ἔσω[ἔσω.. δεῦρ᾽ εἴσιθ᾽ 5th-6th c.BC: Aristophanes Comicus “Plutus” 231 ">Refs 5th c.BC+]; ἡγεῖσθαι ἔσω, φεύγειν ἔσω, [ἔσω [prev. author] “An.” 1.6.5.

__b when a case follows, [Refs 8th c.BC+] prefers the accusative, δῦναι δόμον ϊδος ἔσω [ἔσω αἰχμή 6.10, etc.; ἡγήσατο.. Ἴλιον ἔσω 1.71, etc. ">Refs 8th c.BC+]; more rarely with genitive, κατελθόντ᾽ ϊδος ἔσω [ἔσω 8th c.BC: Odyssea Homerus Epicus “Odyssey” 7.135, compare 8.290 ">Refs 8th c.BC+]; so in Prose and Trag., Κύκλωπος ἔσω βλεφάρων ὤσας [Refs 5th c.BC+]; it generally follows its case, but precedes in [Refs 8th c.BC+]
