Which term describes a part of a play where a character speaks directly to the audience, revealing internal thoughts?

The term that describes a part of a play where a character speaks directly to the audience, revealing their internal thoughts, is known as an "aside." This dramatic device allows the character to express feelings or thoughts that are not heard by other characters on stage, creating a unique connection between the character and the audience. Asides often serve to provide insight into the character's motivations or the plot while also adding an element of dramatic irony, as the audience is privy to information that the other characters do not know.

In contrast, dialogue refers to the spoken exchanges between characters, while a monologue typically involves a lengthy speech by one character that may or may not address the audience directly. The chorus, originating from Greek theatre, serves as a group that comments on the action of the play but does not perform the same function as an aside. Thus, the correct term for a situation where a character reveals their inner thoughts directly to the audience is indeed an aside.
