Answer Details
An aside is something a character says on stage that is meant for the audience alone. It is a theatrical device used to reveal a character's inner thoughts or feelings directly to the audience, without other characters on stage being aware of it. The purpose of an aside is to provide the audience with insight into the character's motivations or to provide additional context to the scene. It is usually spoken in a lower voice or in an aside tone and can be marked by the character turning towards the audience or breaking the fourth wall.
