What is a thesis sentence?
- It conveys the central or main idea of the composition and
indicates how the main idea will be supported.
What is the difference between a thesis sentence and a topic
sentence?
- A thesis sentence governs the content and structure of a whole
composition, whereas a topic sentence guides only one of its parts
or paragraphs.
- The thesis sentence plans the trip, as it were; the topic
sentence shows one of the places that must be passed through to get
to the destination.
Where should the thesis sentence be placed within the composition?
- Generally at the beginning of the composition
- May be the first and only sentence of the first paragraph
- May follow an introductory sentence or two and then come as the
climax of the first paragraph
Are all thesis sentences alike in content and form?
- A thesis sentence is a statement of position, of belief, or of a
point of view, either your own or that of someone else, such as the
author of your assigned reading.
- Much like a good outline, a thesis sentence gives the plan for
the composition.
Divide the thesis sentence into two or three parts.
People who live in the suburbs are alike. (undivided)
People who live in the suburbs are alike in age, race, and politics.
(divided into three parts)
Capital punishment should be abolished. (undivided)
Capital punishment should be abolished because it is useless and
inhumane. (divided into two parts)
The essay is a satire. (undivided)
The essay satirizes younger as well as older people. (divided into
two parts)
Life on this earth may soon be wiped out. (undivided)
Plants, animals, and people (the so-called higher animals) may soon
be wiped out. (divided into three parts)
- The second sentence of each pair above is a brief summary that
tells not only where the composition is going but also how it is
going to get there.
- The composition must discuss each part of the thesis in the
order in which it appears in the thesis.
The division is for the purpose of supporting the thought or
providing proof.
It may rain today. (unsupported)
It may rain today because there are dark clouds in the sky and my

poor. (unsupported)

Do compositions always contain a thesis sentence?
- Expository and argumentative compositions require a thesis
sentence.
- Narrative and descriptive compositions may not require one.
Is the thesis always a single sentence?
- In some cases it may be simpler or clearer to break the thesis
down into more than a single sentence, especially if the main idea
of the composition is unusually complex or if the composition is
long.
- Is the division of the thesis sentence always limited to two or
three parts or supports?
In a short composition of about four to eight paragraphs, plan to
limit the parts or supports of the main idea to two or three.
Practicing the Thesis Sentence
-
The most common form of the supported
thesis sentence first states the subject and then states the
supports.
-
The supports are often introduced by
words or expressions such as the following:
-because -since -as -due to -by -in -in that
-
A punctuation mark, the colon (:), may
substitute for these words and serve the same purpose.
Examples

conceited, unstable, and selfish.

tension it inspires.
