A good paragraph expresses one main idea. This idea is stated in
the topic sentence. In the so-called supporting
sentences the main idea is further developed by giving reasons,
examples, facts, etc. Finally, the paragraphs end with a
concluding sentence, which summarizes the most important point
made in the paragraph. In addition to these three parts, a good
paragraph adheres to the rules of unity (one idea per
paragraph) and coherence (supporting sentences are presented
in a logical order and linked by means of appropriate link words).
