§1.10.1Παρὰ Ἀλεξάνδρου τοῦ γραμματικοῦ τὸ ἀνεπίπληκτον καὶ τὸ μὴ ὀνειδιστικῶς ἐπιλαμβάνεσθαι τῶν βάρβαρον ἢ σόλοικόν τι ἢ ἀπηχὲς προενεγκαμένων, ἀλλ’ ἐπιδεξίως αὐτὸ μόνον ἐκεῖνο ὃ ἔδει εἰρῆσθαι προφέρεσθαι ἐν τρόπῳ ἀποκρίσεως ἢ συνεπιμαρτυρήσεως ἢ συνδιαλήψεως περὶ αὐτοῦ τοῦ πράγματος, οὐχὶ περὶ τοῦ ῥήματος, ἢ δι’ ἑτέρας τινὸς τοιαύτης ἐμμελοῦς παρυπομνήσεως.
From Alexander the grammarian, to refrain from fault-finding, and not in a reproachful way to chide those who uttered any barbarous or solecistic or strange-sounding expression; but dextrously to introduce the very expression which ought to have been used, under the guise of an answer or as confirming the statement or as joining in the discussion about the matter itself, not about the word, or by some other such gentle hint.
