What is exigence, audience, and constraint?

Exigence is the reason or motive that prompts a speaker or writer to create a particular text. It is the problem or issue that calls for a response and motivates the communication.

Audience refers to the specific group of people or individuals for whom a text is intended or directed. Understanding the audience helps shape the content, style, and tone of the communication.

Constraints are the limitations or restrictions that shape the creation and delivery of a particular text. These constraints may be external factors such as time, resources, or societal norms, or they could be internal factors such as the writer's own knowledge or skills. Constraints shape what is possible or realistic within a given context.
