A soliloquy is: an act of speaking one's thought aloud when by oneself or regardless of any hearers, especially by a character in a play. 

Soliloquy is a device often used in drama when a character speaks to himself or herself, relating thoughts and feelings, thereby also sharing them with the audience, giving off the illusion of being a series of unspoken reflections.  

Answer 2

Answer:

Talking to oneself.

Explanation:

 The word soliloquy comes from the Latin: Solus  means 'alone'; loqui  means 'to speak'. In plays, this literary device is used for speeches where the characters talk to themselves, or to the audience rather than to the other characters, which is a way for the audience to know their thoughts. It's almost as 'thinking out loud', but the words are not directed to anyone in particular.
