Final answer:
The term "offstage violence" describes actions in Greek drama that take place out of the audience's view, often narrated instead of shown to elicit a strong emotional response.
Step-by-step explanation:
The term used to describe the part of Greek drama that takes place off-stage, particularly violent actions that occur outside the audience's direct view, is offstage violence. While not a specific term coined in the ancient texts, the concept is well understood in the realm of theatre studies. In classical Greek theatre, violence and other actions were often narrated by characters who had witnessed them or heard about them, rather than being shown onstage. This was partly due to the physical limitations of the theatre spaces and the conventions of Greek dramatic storytelling. Actions described rather than performed allowed the audience to imagine these events, enhancing the emotional and psychological impact of the narrative.
