Soliloquy
* Delivered by a single character, usually alone on stage
* Reveals the character's thoughts and feelings
* Often used to provide insight into the character's motivations or inner conflict
Monologue
* Delivered by a single character, but not necessarily alone on stage
* Can be addressed to other characters, the audience, or no one in particular
* Often used to provide information about the plot, to persuade or convince other characters, or to express the character's opinions or beliefs
Examples
* Soliloquy: Hamlet's famous "To be or not to be" speech is a soliloquy in which he contemplates the pros and cons of suicide.
* Monologue: Mark Antony's speech over Caesar's body in Shakespeare's Julius Caesar is a monologue in which he tries to persuade the crowd to rebel against the conspirators who killed Caesar.
In summary, the main difference between a soliloquy and a monologue is that a soliloquy is delivered by a single character alone on stage, while a monologue can be delivered by a single character to other characters on stage. Soliloquies are often used to reveal a character's thoughts and feelings, while monologues can be used for a variety of purposes, including providing information about the plot, persuading or convincing other characters, or expressing the character's opinions or beliefs.
