The reason to why you are discussing a topic as well as to wha tis motivating Writer to discuss topic.

How purpose is represented:

• Persuasion
• Arguing a view point
• Specifying on a topic

The projects we did throughout the semester all had different purposes such as narrative and informative writing. The narrative is a “Story” a idea built of a experience , opinion or a topic the writer Chooses. A informative, is about evaluating and understanding the topic in a more analytical way .

Without Purpose the ideas of the writer are unclear and without reasoning how can the writer inform or persuade.
