Final answer:
The Nurse in Medea serves as Medea's confidant and plays a significant role in the play.
Step-by-step explanation:
The Nurse in the play Medea by Euripides plays a significant role as Medea's confidant. Her presence is mainly felt in the play's opening lament and in a few speeches addressing diverse subjects not entirely related to the action of the play. The Nurse serves as a foil to young Juliet, delights us with her warmth and earthy wit, and helps realize the tragic catastrophe. Euripides' work focuses on the more human aspects of heroes and includes strong female protagonists, exemplified by Medea.
