WRITING AN ESSAY
WRITING PARAGRAPHS A thesis is a single, focused argument, and most paragraphs prove or demonstrate a thesis through explanations, examples and concrete details. This chapter will help you learn to write and analyse the types of paragraphs common in academic essays.

Start with an Outline: Start with an Outline .A brief outline will make it easier to develop topic sentences and to arrange your paragraphs in the most effective order.You should begin your outline by stating the thesis of your paper:

The English Civil War was caused by a combination of factors, including the empowerment and organization of Puritan forces, the absolutist tendencies of James I and the personal ineptitude of his son Charles I.

Next, list the topic sentences for each of the paragraphs (or sections) of the paper.Writing Topic Sentence:
The English Civil War was caused by a combination of factors, including the empowerment and organization of Puritan forces, the absolutist tendencies of James I and the personal ineptitude of his son Charles I.:
Choose the best among the several topic sentences
Dividing your Argument
Starting a new paragraph is a signal to your reader that you are beginning a new thought or taking up a new point. Since your outline will help you divide the essay into sections, the resulting paragraphs must correspond to the logical divisions in the essay. If your paragraphs are too long, divide your material into smaller, more manageable units; if they're too short, find broader topic sentences that will allow you to combine some of your ideas.
Review:
shift in emphasis or topic suggests that a new paragraph should have been started.
Developing Unified and Coherent Paragraphs
A paragraph is unified when every sentence develops the point made in the topic sentence. It must have a single focus and it must contain no irrelevant facts. Every sentence must contribute to the paragraph by explaining, exemplifying, or expanding the topic sentence. In order to determine whether a paragraph is well developed or not, ask yourself: "
What main point am I trying to convey here?" (topic sentence) and then "Does every sentence clearly relate to this idea?"There are several ways in which you can build good, clear paragraphs.
This section will discuss three of the most common types of paragraph structure:
development by detail, comparison and contrast, and process. F
inally, it will suggest that most paragraphs are built of a combination of development strategies.
Paragraph Development by Detail
This is the most common and easiest form of paragraph development: you simply expand on a general topic sentence using specific examples or illustrations.

Paragraph Development by Comparison and Contrast
You should consider developing your paragraph by comparison and contrast when you are describing two or more things which have something, but not everything, in common.

Paragraph Development by by process involves a straightforward step-by-step description. Those of you in the sciences will recognise it as the formula followed in the "method" section of a lab experiment. Process description often follows a chronological sequence.

Paragraph Development by CombinationVery often, a single paragraph will contain development by a combination of methods. It may begin with a brief comparison, for example, and move on to provide detailed descriptions of the subjects being compared. A process analysis might include a brief history of the process in question. Many paragraphs include lists of examples.http://www.uottawa.ca/academic/arts/writcent/hypergrammar/parout.html#outline
