This document discusses the concept of kairos, which refers to speaking at the right time and in the right way according to the situation. There are three types of kairos: causal, meaning-dependence, and normative. Exigence refers to an imperfection or problem in the environment that prompts a rhetorical response. A rhetorical situation involves nine elements, including the exigence or problem, persons involved, their relationships, location, speaker, audience, method, and institutions that provide context.
