ἐκ δὴ τῶν γραμμάτων τοσούτων τε ὄντων καὶ δυνάμεις      15
τοιαύτας ἐχόντων αἱ καλούμεναι γίνονται συλλαβαί. τούτων
δὲ εἰσὶ μακραὶ μὲν ὅσαι συνεστήκασιν ἐκ τῶν φωνηέντων
τῶν μακρῶν ἢ τῶν διχρόνων ὅταν μακρῶς ἐκφέρηται, καὶ
ὅσαι λήγουσιν εἰς μακρὸν ἢ μακρῶς λεγόμενον γράμμα ἢ εἴς
τι τῶν ἡμιφώνων τε καὶ ἀφώνων· βραχεῖαι δὲ ὅσαι συνεστήκασιν      20
ἐκ βραχέος φωνήεντος ἢ βραχέως λαμβανομένου,
καὶ ὅσαι λήγουσιν εἰς ταῦτα. μήκους δὲ καὶ βραχύτητος

back by the breath, and affording it an outlet downwards round the teeth. These differ in roughness and smoothness, τ being the smoothest of them, θ the roughest, and δ medial or common. This is the second set of three mutes. The three remaining mutes are spoken with the tongue rising to the palate near the throat, and the windpipe echoing to the breath. These, again, differ in no way from one another as regards formation; but κ is pronounced smoothly, χ roughly, γ moderately and between the two. Of these the best are those which are uttered with a full breath; next those with moderate breath; worst those with smooth breath, since they have their own force alone, while the rough letters have the breath also added, so that they are somewhere nearer perfection than the others.
