An Introduction to the Paragraph
In many languages, the
fundamental unit of composition is the paragraph. A paragraph consists of
several sentences that are grouped together. This group of sentences
together discuss one main subject. In U.S. formal academic
English, paragraphs have three principal parts. These three parts are the
topic sentence, body sentences or supporting sentences, and the concluding sentence.
The Topic Sentence
A topic sentence usually
comes at the beginning of a paragraph; meaning, it is usually the first
sentence in a formal academic paragraph. (Sometimes this is not true, but
as you practice writing in our class, please keep to this rule
unless you are instructed otherwise.) Not only is a topic sentence the first
sentence of a paragraph, but, more importantly, it is the most general
sentence in a paragraph. What does "most general" mean?
It means that there are not many details in the sentence, but that the sentence
introduces an overall idea that you want to discuss later in the
paragraph.
For example, suppose
that you want to write a paragraph about the natural landmarks of your
hometown. The first part of your paragraph might look like this:
My hometown is famous for several amazing natural features. First, it
is noted for the Wheaton River, which is very wide and beautiful. Also, on
the other side of the town is Wheaton Hill, which is unusual because it is
very steep.
|
(IMPORTANT: Notice how the first
sentence begins with "My hometown..." a few spaces to the right
of the paragraph edge. This is an indentation. All
paragraphs in English MUST begin with an indentation.)
Note how the first
sentence, My hometown, is famous for several amazing geographical
features, is the most general statement. This sentence is different
from the two sentences that follow it, since the second and third sentences
mention specific details about the town's geography, and are not general statements.
Activity:
Here are some examples
of sentences that cannot be used as topic sentences. Can you figure out why
they are inappropriate?
- My hometown is famous because it is located by
Wheaton River, which is very wide, and because it is built near an
unusually steep hill called Wheaton Hill.
- There are two reasons why some people like to buy
cars with automatic transmission and two reasons why others like cars
with manual transmission.
- Clouds are white.

Explanation:
The problem with
sentence #1 is that it contains too many details. Topic sentences are general,
and details should appear later in the paragraph. A better topic sentence would
be like the one mentioned above, My hometown is famous for several amazing
geographical features.
Sentence #2 is not
appropriate as a topic sentence because it mentions two topics, not just one.
Paragraphs are usually about one main thing and so their topic sentences should
also be about only one main thing.
The problem with
sentence #3 is that it is too general. It is also very boring! Would you
like to read a paragraph with this topic sentence? Most people would not.
We can rewrite sentences
#2 and #3 in the following ways to make it better:
- There are two reasons why some people like to buy
cars with automatic transmission.
OR (in a different paragraph):
- There are two reasons why some people like cars with
manual transmission.
- The shapes of clouds are determined by various
factors.

Supporting Sentences
Consider again the
above-mentioned, short paragraph:
My hometown, is famous for several amazing natural features. First, it
is noted for the Wheaton River, which is very wide and beautiful. Also, on
the other side of the town is Wheaton Hill, which is unusual because it is
very steep.
|
(IMPORTANT: Again, note how this
paragraph is indented on the first line, about five or seven spaces in from the
left-hand edge of the paragraph. Always remember to indent your
paragraphs!)
When a reader reads a
topic sentence, such as My hometown, is famous for several amazing natural
features, a question should usually appear in the reader's
mind. In this case, the question should be like, "What are
the natural features that make Wheaton famous?" The reader
should then expect that the rest of the paragraph will give an answer to
this question.
Now look at the
sentences after the topic sentence. We can see that the second sentence
in the paragraph, First, it is noted for the Wheaton River, which is
very wide and beautiful, indeed gives an answer to this question. That is,
the second sentence gives some explanation for the fact that Wheaton is
a famous town. Similarly, we can see that the third sentence also gives some
explanation for the fact that Wheaton is famous by giving another example of an
"amazing natural feature," in this case, Wheaton Hill.
The second and third
sentences are called supporting sentences. They are called
"supporting" because they "support," or explain, the idea
expressed in the topic sentence. Of course, paragraphs in English often
have more than two supporting ideas. The paragraph above is
actually a very short paragraph. At minimum, you should have at least five
to seven sentences in your paragraph. Here we can see our
paragraph about Wheaton with a few more supporting sentences in bold
font:
My hometown is famous for several amazing natural features. First, it
is noted for the Wheaton River, which is very wide and beautiful. Also, on
the other side of the town is Wheaton Hill, which is unusual because it is
very steep. The third amazing feature is the Big Old Tree. This tree
stands two hundred feet tall and is probably about six hundred years old.

The Concluding Sentence
In formal paragraphs you
will sometimes see a sentence at the end of the paragraph which summarizes the
information that has been presented. This is the concluding
sentence. You can think of a concluding sentence as a sort of topic
sentence in reverse.
You can understand
concluding sentences with this example. Consider a hamburger that you can
buy at a fast-food restaurant. A hamburger has a top bun (a kind of
bread), meat, cheese, lettuce, and other elements in the middle of the
hamburger, and a bottom bun. Note how the top bun and the bottom bun are very
similar. The top bun, in a way, is like a topic sentence, and the bottom
bun is like the concluding sentence. Both buns "hold" the meat,
onions, and so on.
Similarly, the topic sentence and concluding sentence
"hold" the supporting sentences in the paragraph. Let's see how
a concluding sentence (in bold font) might look in our sample paragraph
about Wheaton:
{My hometown is famous for several amazing natural features. First, it
is noted for the Wheaton River, which is very wide and beautiful. Also, on
the other side of the town is Wheaton Hill, which is unusual because it is
very steep. The third amazing feature is the Big Old Tree. This tree stands
two hundred feet tall and is probably about six hundred years old. These
three landmarks are truly amazing and make my hometown a famous place.}
|
Notice how the
concluding sentence, These three landmarks are truly amazing and make my
hometown a famous place,summarizes the information in the paragraph.
Notice also how the concluding sentence is similar to, but not exactly the same
as, the topic sentence.
Not all academic paragraphs
contain concluding sentences, especially if the paragraph is very short.
However, if your paragraph is very long, it is a good idea to use a concluding
sentence.
