Final answer:
In Euripides' play Medea, the Chorus accentuates Medea's foreign status, continually reminding the audience of her barbarian origins and the xenophobic challenges she confronts.
Step-by-step explanation:
The Chorus in Euripides' play Medea consistently reinforces Medea's status as a foreigner and a barbarian. This is evident in their references to her origins and their portrayal of her as distinct from the Greek characters in terms of cultural practices and language. The term barbarian itself stems from the Greek barbaros, meaning 'foreigner,' and was used pejoratively to describe cultures considered less civilized compared to Greek society. The Chorus's emphasis on Medea's foreign nature underlines her isolation and the societal prejudices she faces, comprising a central theme in the play of the xenophobia and difficulties faced by outsiders.
