ὀξύνονται. σύνθετα ὄντα βαρύνονται οἷον εὔπλους, εὔχρους, ἀλκίνους εἰ ἄρα οὖν τὸ διπλοῦς καὶ τριπλοῦς οὐ βαρύνονται, ἀλλὰ περισπῶνται, δηλονότι οὐκ εἰσὶ σύνθετα, ἀλλ´ ἁπλᾶ. Τρίτον δ´ εἰ ἦσαν σύνθετα, κοινὰ ἤμελλον εἶναι τῷ γένει, ὥσπερ ὁ εὔνους καὶ ἡ εὔνους, ὁ εὔπλους καὶ ἡ εὔπλους, ὁ εὔχρους καὶ ἡ εὔχρους· νυνὶ δὲ τὸ θηλυκὸν λέγομεν ἡ διπλῆ καὶ τριπλῆ (Il. Α 128) «τριπλῇ τετραπλῇ τ´ ἀποτίσομεν» ὥσπερ ὁ χαλκοῦς καὶ ἡ χαλκῆ, ὁ χρυσοῦς καὶ ἡ χρυσῆ, δηλονότι οὐκ εἰσὶ σύνθετα, ἀλλ´ ἁπλᾶ παραγωγά, παρὰ γὰρ τοῦ δίς παρήχθη τὸ διπλόος καὶ ἀπὸ τοῦ τρίς τοῦ σημαίνοντος τὸ τρίτον τριπλόος καὶ ἀπὸ τοῦ τετράκις τετραπλόος καὶ ἀπὸ τοῦ πεντάκις πενταπλόος, συγκοπῆς γενομένης τῆς 'κις' συλλαβῆς καὶ ἐπὶ τῶν ἑξῆς ὁμοίως. καὶ τὸ ἁπλόος ἀπὸ τοῦ ἅπαξ παρήχθη. τὸ δὲ πρωτόπλοος καὶ ἁλίπλοος προπαροξύνεται, ὅτι μὴ ἁπλᾶ. Τὰ διὰ τοῦ 'οος' κύρια προπαροξύνεται, Σίστοος, Πείροος, Ἄθοος ὁ καὶ Ἀθόως. λέγεται δὲ καὶ Ἄθους κατὰ συναίρεσιν καὶ Ἄθως. Γένοος ἄρχων, ἀφ´ οὗ Γενοαῖοι ἔθνος Μολοσσίας. τὸ δὲ ὄγδοος, εἰ καὶ ἐπίθετον, προπαροξύνεται, ἐπειδὴ τὰ εἰς 'ος' τακτικὰ βαρύνεται ὑπεσταλμένων τῶν εἰς 'στος', ἕβδομος, ὄγδοος, ἔννατος, δέκατος. τὸ δὲ εἰκοστός, τριακοστός καὶ τἆλλα ὀξύνεται. καὶ τὸ ὀλοός ὀξύνεται ἀπὸ τοῦ ὀλῶ. Τὰ εἰς 'ος' ὑπερδισύλλαβα παραληγόμενα 'υ' συνεσταλμένῳ προπαροξύνεται, σίκυος, Πέρυος ὄνομα ποταμοῦ, Φόγγυος. Αἴγυος ἐθνικόν, οὗ τὸ θηλυκὸν Λυκόφρων λέγει οὕτως «καὶ πάντα πλήσεσθ´ οὕνεκ´ Αἰγύας κυνός, τῆς θηλύπαιδος καὶ τριάνορος κόρης» (v. 850). Θεόπομπος δὲ Αἰγυέας αὐτούς φησι, Παυσανίας δὲ Αἰγύτας. Πατράσυος, Κάνδυος, Ἀλάσυος, Ἐρύγυος, Νώγυος ὄνομα ποταμοῦ. Μίνυος, ἀφ´ οὗ Μινύα πόλις Θεσσαλική. Σίλλυος πόλις Ἰωνίας πρὸς τῇ Σμύρνῃ. τὸ δὲ Τιτυός καὶ εἰλυός ἡ κατάδυσις τοῦ θηρίου ὀξύνεται καὶ τὸ 'υ' οὐκ ἔχει συνεσταλμένον.
They are accented with an acute. But when they are compounds they are barytone, e.g. εὔπλους, εὔχρους, ἀλκίνους. If, then, διπλοῦς and τριπλοῦς are not barytone but are circumflexed, it is clear that they are not compounds but simple words. Thirdly, if they were compounds, they would be common in gender, as ὁ εὔνους and ἡ εὔνους, ὁ εὔπλους and ἡ εὔπλους, ὁ εὔχρους and ἡ εὔχρους; but as it is, for the feminine we say ἡ διπλῆ and τριπλῆ (Il. Α 128) “τριπλῇ τετραπλῇ τ´ ἀποτίσομεν”, just as ὁ χαλκοῦς and ἡ χαλκῆ, ὁ χρυσοῦς and ἡ χρυσῆ. It is clear, then, that they are not compounds but simple derivatives: for from δίς was derived διπλόος, and from τρίς, meaning ‘third’, τριπλόος, and from τετράκις τετραπλόος, and from πεντάκις πενταπλόος, the syllable -κις having been syncopated, and similarly in the following cases. And ἁπλόος was derived from ἅπαξ. But πρωτόπλοος and ἁλίπλοος are accented on the antepenult, because they are not simple. Proper names in -οος are accented on the antepenult: Σίστοος, Πείροος, Ἄθοος, who is also called Ἀθόως. He is also called Ἄθους by contraction, and Ἄθως. Γένοος, a ruler, from whom the Γενοαῖοι, a people of Molossia. But ὄγδοος, although an adjective, is accented on the antepenult, because the ordinal numerals in -ος are barytone, with the exception of those in -στος: ἕβδομος, ὄγδοος, ἔννατος, δέκατος. But εἰκοστός, τριακοστός, and the rest are accented with an acute. And ὀλοός is accented with an acute, from ὀλῶ. Words in -ος of more than two syllables, with a contracted upsilon in the penult, are accented on the antepenult: σίκυος, Πέρυος (the name of a river), Φόγγυος. Αἴγυος, an ethnic name, whose feminine Lycophron speaks thus: “καὶ πάντα πλήσεσθ´ οὕνεκ´ Αἰγύας κυνός, τῆς θηλύπαιδος καὶ τριάνορος κόρης” (v. 850). But Theopompus says Αἰγυέας for them, and Pausanias Αἰγύτας. Πατράσυος, Κάνδυος, Ἀλάσυος, Ἐρύγυος, Νώγυος (the name of a river). Μίνυος, from whom Μινύα, a Thessalian city. Σίλλυος, a city of Ionia near Smyrna. But Τιτυός and εἰλυός, ‘the lair of the beast’, are accented with an acute, and the upsilon is not contracted.
