c. 27 ἀντίθετον μὲν οὖν ἐστι τὸ ἐναντίαν τὴν ὀνομασίαν ἅμα

καὶ τὴν δύναμιν τοῖς ἀντικειμένοις ἔχον, ἢ τὸ ἕτερον τούτων: Aristot. _Poet._ vi. 18 λέγω δέ, ὥσπερ πρότερον εἴρηται, λέξιν εἶναι τὴν διὰ τῆς ὀνομασίας ἑρμηνείαν: Dionys. Hal. _de Demosth._ cc. 18, 34, 40: Demetr. _de Eloc._ §§ 91, 304.

=ὀνοματικά, τά.= =70= 18, =102= 16, 17, =132= 7. _Nouns substantive._ Lat. _nomina substantiva_.

=ὀξύς.= =126= 5, 8, 10, =128= 6, 8. _Acute_ (accent), _high_ (pitch). Lat. _acutus_. So =ὀξύτης= =126= 14. Cp. s.v. βαρύς, p. 292 _supra_. In Aristot. _Poet._ c. 20 ὀξύτητι καὶ βαρύτητι καὶ τῷ μέσῳ = ‘according as they [the letters] are acute, grave, or of an intermediate tone.’

=ὀξύτονος.= =128= 9. _With high pitch or acute accent._ Lat. _qui acutum tonum s. accentum habet_.

=ὅρασις.= =118= 24. _Seeing_, _the act of sight_. Lat. _visus_.

=ὀρθός.= =106= 19. _Nominative._ Lat. _rectus_ (_casus_): viz. ‘uninflected.’ In =102= 19 ‘primary,’ as opposed to ‘secondary’; in =108= 3 ‘active,’ as opposed to ‘passive.’ In =258= 25 and =262= 5 the meaning is ‘correct’; in =90= 6 perhaps ‘tense’ (see the exx. given in L. & S. under the heading ‘excited’), the opposite of ὕπτιος (_supinus_).

=ὁρίζειν.= =132= 22, =166= 1, =234= 21. _To define_, _to limit_. Lat. _definire_.

=ὅρος.= =182= 13, =200= 25, =210= 5. _Standard_, _condition_, _boundary_. Lat. _regula_, _condicio_, _finis_. With the sense _norma et regula_ in =182= 13 cp. Long. _de Subl._ xxxii. 1 ὁ γὰρ Δημοσθένης ὅρος καὶ τῶν τοιούτων, Dionys. H. _de Demosth._ c. 1 ἧς (λέξεως) ὅρος καὶ κανὼν ὁ Θουκυδίδης.

=οὐρανός.= =142= 12, =144= 19, =150= 6, =220= 23. _Palate._ Lat. _palatum_. In the margin of R (with reference to =142= 12) there is the note: τὴν ὑπερῴαν φησίν. This sense of οὐρανός is found several times in Aristotle (see Bonitz’ _Index_), and not (as has sometimes been supposed) for the first time in Dionysius. Cp. the converse _caeli palatum_ in Ennius _apud_ Cic. _de_ _Nat. Deor._ ii. 18. 48 “sed dum, palato quid sit optimum, iudicat [Epicurus], caeli palatum (ut ait Ennius) non suspexit.”

The metrical foot so called, consisting of three short syllables and one long in four possible orders—(1) –ᴗᴗᴗ, (2) ᴗ–ᴗᴗ, (3) ᴗᴗ–ᴗ, (4) ᴗᴗᴗ–. These four varieties are sometimes called the _first_, _second_, _third_, and _fourth_ paeon respectively. Cp. Aristot. _Rhet._ iii. 8. 4-6, Cic. _de Orat._ iii. 47. 183, Quintil. ix. 4. 47; and see Demetr. p. 296, s.v. παιών.
