Discussion of accentuation patterns for feminine nouns ending in -ας and -ης, and rules for the singular dative accent; examples (e.g., Φοβερά, Ἀθηνᾶ, Μήδεια) and dative forms (μηνί, φωτί).
Αἱ εἰς 'ας' καὶ 'ης' γενικαὶ θηλυκαὶ ἀπὸ μὲν ὀξυνομένων εὐθειῶν καὶ περισπωμένων περισπῶνται, ἡ φοβερά τῆς φοβερᾶς, ἡ καλή τῆς καλῆς, ἀλλὰ καὶ Ἀθηνᾶ Ἀθηνᾶς καὶ χρυσῆ χρυσῆς. αἱ δὲ ἀπὸ βαρυτόνων πρὸ μιᾶς ἔχουσι τὸν τόνον, Μήδεια Μηδείας, ὁσία ὁσίας. τὸ μιᾶς περισπώμενον ἀπὸ τοῦ μία βαρυνομένου Ἴωσί τινες ἀνατιθέασι καὶ ἔτι ἀπὸ τοῦ ἴα τὸ ἰᾶς. ὁμοίως καὶ τὰς δοτικάς. {1Περὶ τόνου τῆς ἑνικῆς δοτικῆς.}1 Πᾶσα δοτικὴ δισύλλαβος εἰς 'ι' ἐκφωνούμενον λήγουσα, ἑνική τε καὶ πληθυντικὴ ὀξύνεται μηνί μησί, φωτί φωσί. Πάλιν τῶν συνῃρημένων γενικῶν αἱ δοτικαὶ διὰ τὴν αὐτὴν αἰτίαν βαρύνονται, ἦρι, κῆρι· ἔτι ἀπὸ συναιρέσεώς εἰσι τὸ Θέτιι Θέτι »πάντα Θέτι καλλιπλοκάμῳ (Σ 407), μάστιι, μάστι «μάστι αἰὲν ἔλαυνε» (Ψ 500),
Feminine genitives in -ας and -ης, when derived from acute-nominated and circumflex-nominated nominatives, take the circumflex: ἡ φοβερά, τῆς φοβερᾶς; ἡ καλή, τῆς καλῆς; and likewise Ἀθηνᾶ, Ἀθηνᾶς, and χρυσῆ, χρυσῆς. But those derived from barytone forms have the accent on the penult: Μήδεια, Μηδείας; ὁσία, ὁσίας. The circumflexed μιᾶς, derived from the barytone μία, some attribute to Ionic usage, and likewise ἰᾶς from ἴα. Similarly also the datives.
{1On the accent of the singular dative.}1 Every disyllabic dative ending in pronounced -ι, both singular and plural, is accented with an acute: μηνί, μησί; φωτί, φωσί. Again, in the case of contracted genitives, the datives for the same reason take the grave: ἦρι, κῆρι; and further, from contraction are Θέτιι, Θέτι—“πάντα Θέτι καλλιπλοκάμῳ (Σ 407)”; μαστίι, μαστί—“μάστι αἰὲν ἔλαυνε” (Ψ 500).
