Hello,

There are four different modes of discourse that one should keep in mind before starting a project. They are as follows:

NARRATION:-

Narration is a form of story telling. It comprises of mixing a series of events, normally in a consecutive order. The incidents described can be fictional or nonfictional. If the incidents have actually occured, we give the writing a different name like biography, autobiography, history, after action report, or a newspaper report.

DESCRPITION:-

Description tells what things are like corresponding to the five senses. A descriptive essay, or a descriptive passage inside a story, narrates how things look, sound, feel, taste, and smell. Nouns and adjectives can express what a person, place, or thing are like in their material characteristics. But description sometimes tries to do more than to allow readers to visualize characters, settings, and actions. It can also grow a mood or atmosphere, and this is done by the use of simile and various metaphors.

EXPOSITION:-

Exposition is the type of writing that is used to impart information. The prefix " Ex- " is derived from Greek through Latin and means "out, or away from." So exposition means "to place out," and, also the thing that is placed out for us to see and understand is the information. This variety of writing has various subtypes, the most common one is the process analysis, definition, classification and division, comparison and contrast, cause and effect, and problem and solution.

ARGUMENT:-

The motive of argument is to convince with the help of logic. An argument is done on a basis of belief or opinion that the writer thinks is correct. The statements of this type of opinion is called a "thesis." It is normally done explicitly infront of the beginning of the argument. To convince readers that his opinion is correct, the writer should develop a case to support the thesis. Developing a case needs giving reasons for believing the thesis, and then giving logics to support the reasons. If the reader has accepted the reasons and the evidence, then he has surely agreed with the thesis.

Hope this helps.....
