How does exile serve as a useful metaphor for madea's emotional states in the play?

Euripides links the themes of exile and the position of women. When emphasizing the circumstances women must bear after marriage (leaving home, living among strangers), Medea is reminding us of the conditions of exile. Her position, then, is doubly grave, as she is an exile in the ordinary sense and also an exile in the sense that all women are exiles. She is also a foreigner, and so to the Greeks she will always be "barbarian."
