What do we call the path an actor takes from one side of the stage to the other?

The correct term for the path an actor takes from one side of the stage to the other is "crossover." In theatrical terminology, a crossover specifically refers to the area at the back of the stage or behind the set where performers can move from one side to another without being visible to the audience. This movement is essential for maintaining the continuity of the performance and ensuring that actors can change positions or entrances without disrupting the flow of the scene. The use of a crossover is a practical element of staging that helps actors transition smoothly between various parts of the performance while keeping the audience focused on the action taking place on stage.
