Soliloquy is a common psychological,physiological,and linguistic phenomenon,which refers to the act of speaking to oneself.As a form of intrapersonal communication,soliloquy helps the speaker regulate emotions,leading to a certain degree of relaxation,self-satisfaction,and self-reflection,thus playing a positive role.Under certain conditions,soliloquy can transform from intrapersonal communication to interpersonal communication,with the transformation being contingent on the context,purpose,and response from others.Conveying implicit meanings and maintaining an active position are two fundamental pragmatic rhetorical functions of soliloquy as a strategy.Based on these functions,numerous specific pragmatic rhetorical functions can be derived.
