The body of an essay comprises (of) several paragraphs all centred on providing support for the thesis statement in the introduction. Each paragraph usually follows an organizational pattern, beginning with a claim (that relates back to the thesis), which is supported with details provided in subsequent sentences.
Make use of appropriate transitions in the interest of unity, clarity and cohesion. Transitions are words and or phrases that are used as ‘bridges’ from one idea, sentence or paragraph, to the next. Like any other writing aid, they should not be over used or randomly placed throughout the piece, but should be used wherever they work best. Transitions are used to:
Introduce or emphasize a point – another key point, in fact, indeed etc
Show location – above, between, throughout etc
Compare and contrast items – also, however, in spite of this etc
Conclude – as a result, lastly etc
Add information – in addition, for instance etc
Clarify – for example, in other words etc
Show time – immediately, in the mean time etc
The length of each paragraph is generally determined by the amount of supporting information presented in developing the main point being discussed and the limitations (time and word limit) with which one is working. One should, however, avoid extremes, as too short a paragraph may imply that the main point should have been a supporting point and/or that the main point was not properly developed. Too long a paragraph, on the other hand, often entails repetition and poor organization of points. This will cause the reader/examiner to lose interest.
