Readers also expect paragraphs to relate to each other as well as to the overall purpose of a text. Establishing transitional sentences for paragraphs can be one of the most difficult challenges you face as a writer because you need to guide the reader with a light hand. When you are too blatant about your transitions, your readers may feel patronized.

To highlight the connections between your ideas, you can provide transitional sentences at the end of each paragraph that look forward to the substance of the next paragraph. Or, you can place the transition at the beginning of a paragraph looking backward, as Valerie Steele does in the following example:

Can a style of dress hurt one's professional career? True to form most academics deny that it makes any difference whatsoever. But a few stories may indicate otherwise: When a gay male professor was denied tenure at an Ivy League university, some people felt that he was punished, in part, for his dress. It was "not that he wore multiple earrings" or anything like that, but he did wear "beautiful, expensive, colorful clothes that stood out" on campus. At the design department on one of the campuses of the University of California system, a job applicant appeared for her interview wearing a navy blue suit. The style was perfect for most departments, of course, but in this case she was told--to her face--that she "didn't fit in, she didn't look arty enough."

Another bit of evidence that suggests dress is of career significance for academics is the fact that some universities (such as Harvard) now offer graduate students counseling on how to outfit themselves for job interviews. The tone apparently is patronizing ("You will need to think about an interview suit and a white blouse"), but the advice is perceived as necessary.

The phrase "another bit of evidence" beginning the second paragraph refers back to the topic sentence that began the first paragraph, "Can a style of dress hurt one's professional career?"

When evaluating your transitions from paragraph to paragraph, question whether the transitions appear too obtrusive, thereby undercutting your credibility. At best, when transitions are unnecessary, readers perceive explicit transitional sentences to be wordy; at worst, they perceive such sentences as insulting. (After all, they imply that the readers are too inept to follow the discussion.)

Vary the length of paragraphs to reflect the complexity and importance of the ideas expressed in them. Different ideas, arguments, and chronologies warrant their own paragraph lengths, so the form of your text should emerge in response to your thoughts. To emphasize a transition in your argument or to highlight an important point, you may want to place critical information in a one- or two-sentence paragraph.
