The Role of Soliloquy and Aside in Dramatic Literature

In dramatic literature, particularly within the works of Shakespeare, soliloquies and asides hold significant weight in character development and thematic exploration. For example, in Macbeth, the title character often uses soliloquies to reveal his ambitious thoughts, internal conflicts, and descent into madness. In a similar vein, consider the character of Iago in Othello. Iago frequently employs asides to communicate his true intentions to the audience while deceiving other characters.
