ἀλλʼ εἰ ἐπακολουθῶν τις αὐτοῖς πύθοιτο αὐτὸ δέ τοῦτο τὸ κτᾶσθαι ὅτι ὀρθῶς εἴρηται, ἀφʼ οὖ καὶ τὸ χρᾶσθαι ἀπο- δείκνυμεν, πόθεν ἴσμεν;ʼ φήσουσιν ὅτι ἐν τῇ συνηθεία λέ- γεται. τοῦτο δὲ λέγοντες δώσουσι τὸ τῇ συνηθείᾳ δεῖν ὡς κριτηρίῳ προσέχειν, ἀλλὰ μὴ τῇ ἀναλογίρ.

But if someone follows their reasoning and asks, “How do we know that this very form ktasthai, from which we also prove chrasthai, is correctly spoken?” they will say that it is used in customary speech. By saying this they will concede that we must attend to custom as criterion, not to analogy.

Mais si quelqu’un, poursuivant leur raisonnement, demandait: «Comment savons-nous que κτᾶσθαι lui-même, par lequel nous démontrons χρᾶσθαι, est correctement dit?», ils répondraient qu’on le dit dans l’usage. En disant cela, ils accorderont qu’il faut s’attacher à l’usage comme critère, et non à l’analogie.
