What does purpose and audience mean in writing?

Purpose in writing refers to the reason an author creates a piece, such as to inform, persuade, entertain, or express emotions. Audience denotes the specific group of readers the writer intends to reach, which influences the tone, style, and content of the writing. Understanding both purpose and audience is essential for effective communication, as it shapes how information is presented and received. Tailoring writing to fit these elements enhances clarity and engagement.
