This article argues for the rejection of εὐθυντής—Jeremiah Markland’s conjecture, accepted by the OCT—at Euripides Suppliant Women 442, and makes a case for the retention of αὐθέντης. It shows that εὐθυντής is ill-suited to the immediate context and unlikely in tragedy, and suggests that it is a term coined by Plato in the middle of the fourth century.
