In drama what is the definition of aside?

In drama, an aside is a line or speech delivered by an actor directly to the audience, typically out of the hearing of other characters on stage. Asides are often used to provide the audience with information or insight about the character's thoughts or feelings that the other characters are not privy to. By breaking the fourth wall, asides can create a sense of intimacy between the actor and the audience. While asides are often humorous in nature, they can also be used for dramatic effect, to convey important information, or to emphasize the character's inner struggles and emotions. Asides can be an effective tool for playwrights to provide additional context or depth to the play's narrative.
