Think about your own paragraphs. Then after drafting your paragraphs, you will need to revisit them and ensure that there's a nice flow between and within them. In other words, that there's coherence and cohesion in your written work. You can think of coherence in terms of bricks that make up a building. If the bricks or any of the bricks is misplaced, the building might collapse. Coherence can happen at different levels: at the level of the sentence, at the level of the paragraph, or even at the level of the essay. Here's an example where coherence breaks down. "I opened my book, scribbled some notes on the page, turned to the next page, and did my laundry." Which part of the sentence jars here? Clearly, the fact that I did my laundry. It doesn't fit in the sequence of ideas presented here, so coherence breaks down. It could rather read as follows: "I opened my book, scribbled some notes on the page, turned to the next page, and wrote a poem." Cohesion on the other hand is like the cement that holds the bricks in place. Both are important for the building to hold. Here's an example where ideas are not cohesive. "I listened to the radio. I heard that there will be a sale on jeans. I headed to the shops." These ideas could be made more cohesive by stating, "I listened to the radio. I heard that there will be a sale on jeans. Therefore, I headed to the shops." Linking words like "therefore" allow you to draw links between ideas and paragraphs. In relation to your essay, coherence and cohesion are essential for your argument to hold. Your ideas need to be presented in a coherent manner. The point speeds in your paragraphs need to be consistent with one another and cannot contradict your overall argument. For example, if you are arguing that tobacco smoking causes cancer in one paragraph, you cannot argue that tobacco smoking has medicinal values in the next paragraph. The second paragraph will clearly contradict your first paragraph. Likewise, there needs to be clear links between paragraphs, so that the reader can easily follow your line of thought. Using words such as also, in addition, moreover, furthermore, to add similar ideas and words such as but, however, nevertheless, to add different ideas can enhance the flow in your writing.
