Essay can come in many shapes, types, textures, and flavours. Traditionally
essays are categorized in the areas outlined below; however, essay purposes and patterns can overlap. Few writers write with just one purpose in mind. Similarly,
essay patterns today rarely exist in their pure form. You may view these essay
patterns as a continuum of interlocking options.

Narrative essays tells a story. It is often difficult to determine whether a 
narrative is an essay or a short story. Only the author knows for sure 
whether the characters in the essay are real or imaginary and whether 
the events are literally true or slightly embroidered. 
 

An expository essay is centered around a main idea expressed in the 
first paragraph. The essay's body elaborates upon the main idea with 
a blend of fact and opinion; the writer's purpose, audience, and tone 
determine this balance. 
 

Argumentation is a form of exposition that adopts a position to be 
proved. There are two routes to convincing your audience -- through 
logic (the head) and emotion (the heart). Argumentation in its pure 
form appeals primarily to the intellect; the writer builds a logical case 
through verifiable evidence. 
 

Persuasion is a form of exposition which attempts to convince the 
audience of a claim, or thesis, through appeals to both the heart and 
the head. Persuasion differs from argumentation in the degree to which 
emotion enters into the discussion. More emphasis is placed on emotional 
appeals which are meant to entice the audience to take some from of action.
