Paragraph Coherence
When something coheres it fits together, it makes sense. Coherence in a paragraph is achieved when the sentences flow smoothly from one to another without awkward breaks in rhythm or meaning.
Coherence is achieved by arranging sentences in the most effective order, using transitional words and phrases, repeating key words and phrases, and using parallel structures. These techniques knit the sentences of a paragraph into a tight structure. Coherence is also a feature of the essay as a whole and is achieved by using transitions to link paragraphs. As originally written the following paragraph lacked coherence; it seemed to jump from idea to idea. In the revision, coherence is achieved by (1) repositioning a sentence, (2) repeating a key phrase, and (3) adding a transition.
Arrange Sentence in the most Effective Order
At the most basic level, coherence in a paragraph comes from organizing the ideas and facts in a sensible pattern. Sentences in a paragraph are usually arranged according to one of three patterns: (1) a chronological (time) order, (2) a spatial order, or (3) a logical order. The most suitable arrangement depends on purpose, subject, and audience. Whichever pattern you choose, follow it consistently and thoughtfully to knit the ideas and elements of your paragraph into a seamless whole that your reader can easily follow.
Chronological Order
Chronological order, or time order, presents events as they occurred.
A personal story, a report on an automobile accident or historical event, and the steps in a process, for example, would naturally be related in chronological order. In the following paragraph Ming-Yee Wai uses chronological order to tell about a disturbing memory.
I clearly remember my sixth birthday because Dad was in the hospital with pneumonia. He was working so hard he paid very little attention to his health. As a result, he spent almost the entire summer before I entered the first grade in the hospital. Mom visited him nightly. On my birthday I was allowed to see him. I have memories of sitting happily in the lobby of the hospital talking to the nurses, telling them with a big smile that I was going to see my dad because it was my birthday. I couldn’t wait to see him because children under 12 were not allowed to visit patients, so I had not seen him in a long time. When I entered the hospital room, I saw tubes inserted into his nose and needles stuck in his arm. He was very, very thin. I was frightened and wanted to cry, but I was determined to have a good visit. So I stayed for a while, and he wished me a happy birthday. When it was time to go, I kissed him good-bye and waited until I left his room to cry. - Grace Ming-Yee Wai, “Chinese Puzzle”
Spatial Order
Spatial order is used to describe a person, place, or thing. The writer begins at a particular point and moves methodically in one direction, say, from top to bottom, left to right, far to near, front to back, outside to inside, or, as in the following paragraph, from the perimeter of the yard towards its centre.
My back yard, compared to others in the neighborhood, wasn’t large.
It measured 70 metres in length and was about 45 metres wide. In the winter, all of my mother’s gardens which lined our lot were covered with snow. The old clothesline, where my mother hung our laundry to dry in the summer, stood at the back of the lot, unused and lonely. The only thing that was important to me in our back yard, right in the middle, was the tiny skating rink my father made for me and flooded every night. In my dreams, this rink was the first step towards the National Hockey League.
Logical Order
A logical pattern of organization can take many forms, depending on the subject matter and the writer’s purpose. In organizing a paragraph, it may be most logical to move from the easiest to understand aspects of the subject to the most difficult, from the least important examples to the most important, from the specific to the general or from the general to the specific, or from the least controversial elements to the most controversial, to name just a few possible patterns.
The following paragraph begins with a strong but general topic sentence; each sentence thereafter narrows the subject until the last zeroes in on the writer’s point.
There is scarcely a corner of human affairs that Shakespeare doesn’t touch upon, nor a topic for which he fails to supply a memorable quote. All of this has led, predictably, to every trade and profession claiming him for their own. There have been any number of attempts to prove that before he turned his hand to writing plays he was a lawyer, a soldier, a physician, an astronomer, a printer, a sportsman, a gardener, and heaven alone knows what else. And of all of these guesses as to what he did at Stratford before coming to his London career, one that seems nearest the mark is gardening. This does not mean, of course, that he would tramp off of a morning, spade and hoe slung over his shoulder like a pikeman’s weapons, to delve in the soil of Lord So-and-so’s gardens and orchards. What it does imply is that Shakespeare was a countryman long familiar with the growth of plants in woodlands, fields, and cottage and kitchen gardens. He may well have tended a garden of his own. -Frank J. Anderson, “Shakespeare in the Garden”




Whether it is first or last or someplace in the middle, whether it has a transitional element, or whether it is explicitly stated or merely implied, the topic sentence is the point of departure for writing an effective paragraph. How you develop-clarify and support-your topic sentence depends on how you answer the question, “Why or how is this so?” Consider, for example, the following topic sentence:
