The body of the paragraph should then include specific, relevant details to support and develop the topic. Transitional phrases should be used to logically connect the details. The concluding sentence should draw conclusions based on the discussed details or indicate the significance of the topic. Examples are provided of effective topic sentences, details, transitions, and conclusions to illustrate how to construct a cohesive paragraph.
