What is The struggle that gets the plot under way called?

The struggle that gets the plot under way is called the inciting incident.

Here's why:

* Inciting Incident: This is the event that sets the story's main conflict in motion. It disrupts the protagonist's ordinary life and forces them to take action.

* Example: In "The Hunger Games," the inciting incident is the selection of Katniss Everdeen's younger sister, Prim, to participate in the Hunger Games. This forces Katniss to volunteer in her place, initiating the story's central conflict.

Without the inciting incident, the plot wouldn't have a reason to exist. It's the catalyst that launches the protagonist on their journey and drives the story forward.
