TOPIC SENTENCES
Topic sentences are the “thesis statements” of paragraphs; therefore, they are both a part of keeping the promise made by the thesis, as well as a sub-promise that should be kept by the paragraphs. They are usually the first sentence in the paragraph. The reader expects topic sentences to provide proof of one aspect of the thesis sentence as well as to provide an indication of what will follow in the paragraph.
A topic sentence is NOT simply a statement of fact. A fact does not contain any controlling ideas that can be easily explained, described, illustrated or analyzed.
There are two kinds of topic sentences:
A statement of opinion contains some form of judgment and the paragraph will support the opinion in the topic sentence.
Example:
The computer is the greatest invention of the twentieth century.
A statement of intent contains no opinion; instead, it informs the reader of what will be objectively explained in the paragraph.
Example:
The common seasoning monosodium glutamate (MSG) has negative side effects.
Topic Sentence Functions
An effective topic sentence:
Relates to the thesis.
Sets up a claim, assertion, argument, evaluation, analysis.
Contains controlling ideas about the topic that need to be developed in the
sentences that follow.
Is the most general sentence in the paragraph. Orients the reader.
Provides a context for understanding what follows. Explains the relationships among elements. Summarizes the rest of the paragraph.
Promises what will follow.
Guidelines for Topic Sentences
A topic sentence must be a complete sentence to perform all the necessary functions.
Weak: Some types of birth control should be provided by schools.
Better: Topreventunwantedpregnanciesandsexuallytransmitteddiseases,schools
should provide every form of non-prescription birth control available.
A topic sentence must predict or promise what follows, so it cannot be a question.
Weak: Should schools provide free computers for their students?
Better: Sinceschoolsshouldassiststudentsintheirstudiesandpreparethemfortheir future careers, they must offer students the technological advantage of free and easy access to computers.

Phrases such as “I think” or “in my opinion” may muddle or weaken topic
sentences. Your writing is always your opinion, so you don’t need these phrases
unless they are central to the idea that you are trying to convey.
Weak: I think that it is important for every woman to carry mace or pepper spray.
Better: Asviolentcriminalstakeoverthecitystreets,womenmustcarrymaceorpepper
spray to protect themselves.
The topic sentence should provide clear relationships among all of its elements so that it can provide a framework for understanding the rest of the paragraph.
Weak: Historians record only dry statistics; we should read novels.
Better: Accuratehistoricalnovelsgiveusadeeperunderstandingofthepastthandothe
dry collection of facts and statistics that pass for history texts.
A topic sentence needs to be clear and specific, so that it can predict and summarize the rest of the paragraph for the reader.
Weak: Public transit is terrible.
Better: Incapableofprovidingreliable,comfortableservice,theSanFranciscoMunicipal
Transit system is failing its ridership.
A topic sentence must be coherent so that the reader can use it as a key to the rest of the paragraph.
Weak: The differences of their socioeconomic classes, indeed, were not more potent than the already inherent differences among the population.
Better: Bosniaissplitapartnotbyanyeconomicclassdifferences,butbyracialand ethnic conflicts.
Because the topic sentence is a reference for the rest of the paragraph, it needs to be exceptionally clear. If there is figurative language in a topic sentence, the wording should be such that the reader does not need to understand the allusion to understand the sentence.
Weak: The Surgeon General must be the Hercules that slays the Hydra of chemical addictions.
Better: AsHerculesslewHydra,theSurgeonGeneralmustdefeatthemany-headed monster that is chemical addiction.
Supporting Sentence Functions
The supporting sentences (the rest of the paragraph) must:
Fulfill the promise set by the topic sentence.
Be on the same topic.
Relate to each other and the topic sentence in a manner established by the topic
sentence.
Weak: I think that it is important for every woman to carry mace or pepper spray.

EXERCISE: Below is a hypothetical essay assignment. With this assignment in mind,
determine if any of the topic and thesis sentences for the following three “essay skeletons”
would lead to an effective essay. If not, why?
Essay Assignment:
We all have in our lives certain types of people we tend to avoid: aggressive types, “nosy” types, people who monopolize every conversation with talk about themselves, people who always seem to be bad-tempered. Identify one type of person you tend to avoid, and then, in a well-organized and well-developed essay, explain why you avoid that type of person.
Essay Skeleton # 1

Topic Sentence: Besides being possessive, such males can also be incredibly stingy with money.
Essay Skeleton # 2
Thesis: Over the years, I have learned to avoid strict teachers because they give too much homework, show no understanding when a student turns in assignments late, get impatient instead of helping when students don’t understand the subject matter, and often yell at the class.
Topic Sentence: At age six, I entered school.
Topic Sentence: Later on, I got into the sixth grade. Topic Sentence: Eventually, I went on to high school. Topic Sentence: Finally, I went to college.
