Soliloquy vs. Monologue

Soliloquy and monologue cover very similar ground, but there are some important differences between the two words.Soliloquy (from the Latin solus “alone” and loqui “to speak”) at its most basic level refers to the act of talking to oneself, and more specifically denotes the solo utterance of an actor in a drama. It tends to be used of formal or literary expressions, such as Hamlet’s soliloquies. Monologue (from Greek monos "alone" and legein "to speak") may also refer to a dramatic scene in which an actor soliloquizes, but it has other meanings as well. To a stand-up comedian, monologue denotes a comic routine. To a bored listener, it signifies a long speech uttered by someone who has too much to say.
