A concluding sentence is the last sentence of a body paragraph, and it reminds the reader of how everything in the paragraph connects back to its main idea and the thesis. A writer must be careful, however, because the concluding sentence of a body paragraph does not simply repeat exactly what its topic sentence said. Rather, much like the conclusion paragraph of an essay, a concluding sentence needs to leave the reader with a final impression that sums up what its entire paragraph is about. To do so, it will usually touch on the same ideas as the topic sentence but phrase them differently by including concepts that the paragraph discussed as it developed.
