What is a prompt in drama?

In drama, a prompt refers to a cue or direction given to an actor or performer to initiate dialogue or action. It can be a line of text, a gesture, or an action that encourages the actor to respond or continue the scene. Prompts are often used in rehearsals to help actors remember their lines or to stimulate spontaneous performances. They can also serve as a tool for directors to guide the flow of a scene.
