άσπιλος

From LSJ

ὅτι μέντοι καὶ ἡ χρῆσις τῶν τρόπων, ὥσπερ τἆλλα πάντα καλὰ ἐν λόγοις, προαγωγὸν ἀεὶ πρὸς τὸ ἄμετρον, δῆλον ἤδη, κἂν ἐγὼ μὴ λέγωhowever, it is also obvious, even without my saying so, that the use of figures of speech, like other literary adornments, is something that has always tempted toward excess
