The overall subject of a paragraph or essay is the theme. Topics are brief and are described with a single word or phrase. The primary concept is a whole phrase that incorporates the topic as well as the author's thoughts on it. A "subject sentence" is one in which the author expresses the primary point of his paragraph. The other sentences are called "supporting sentences". They make explicit what is implied by the subject sentence.
In the following passage, the topic is "religion and science". The main idea is expressed in the final sentence: "Science and religion are two aspects of human nature that are mutually beneficial." Supportive statements include "science has been the greatest force for good in human history" and "without religion there would be no hope for mankind".
The topic sentence is written in the form of a question, and it gives a brief overview of the topic being discussed. It cannot be omitted from a topic sentence without changing its meaning greatly; instead, it should be replaced by something that still provides information about the topic while keeping the focus on the same idea. For example, "Religion and science are two aspects of human nature that are mutually beneficial - Science has been the greatest force for good in human history, while religion has prevented many wars and atrocities throughout history."
As you can see, the topic sentence "Is the topic sentence the main idea?" has multiple answers depending on how you look at it.
The sentence that represents the primary concept of a paragraph is known as a subject sentence. A subject sentence is the sentence in which the main concept of a paragraph is stated. This main concept can be expressed in several ways, such as by using nouns, verbs, adjectives, and adverbs.
For example, the main concept in the first paragraph quoted above is "mammals". The subject sentence that expresses this concept is therefore "Mammals are a class of organisms divided into tetrapods and fish."
Sentence diagrams are useful tools for identifying the main ideas in a piece of writing. They show the relationship between sentences by connecting words or phrases between them. Each line represents a separate thought or idea. The beginning of a new line indicates a new sentence. The only exception is when two sentences contain identical content, in which case they can be joined with a semicolon instead.
In summary, the main idea of a paragraph is expressed by a subject sentence. Other sentences help explain or support this subject sentence. Sentence diagrams can help identify the main ideas in your writing.
The other part of the story idea is called the "detail." This is made up of smaller ideas called "details." The detail helps to explain how and why the subject matter is important.
In short, the main idea is the central thought or concept of the story that everyone will understand. It must be stated clearly in the first sentence or two of the story. The other sentences or paragraphs should help explain how and why this central thought is important. These explanations can be in the form of details or examples. For example, if the story is about trees, the main idea might be "Trees are important because they provide us with oxygen." This statement alone won't tell anyone much about what kind of trees or how they affect oxygen levels. To make things more interesting, we could add details such as "Trees that produce lots of oxygen are called "forest trees. "" or "Some trees such as elm trees have been known to grow as fast as five feet per day. " These details help us understand how and why providing oxygen for us is important. They make the story more interesting to read because we get to learn more about something we care about.
A topic sentence is a sentence that opens a paragraph by conveying the main topic of that paragraph. Similarly to how the thesis statement provides the primary concept of the document at the essay level, the subject phrase provides the key idea at the paragraph level. In general usage, it is correct to say that any sentence that introduces a paragraph is a topic sentence.
Often, but not always, the topic sentence will be the first sentence of the paragraph. However, it can also be the last sentence of the paragraph, or even within the paragraph itself. For example: "People think that dogs are man's best friend because they are loyal and loving, but the true reason is because they are hungry and we give them food." Here the topic sentence is the second sentence of the first paragraph, but it could just as easily have been the third or fourth sentence of that paragraph - in fact, it almost certainly would have been the fourth since the first three sentences describe very different reasons for why people think that dogs are man's best friend.
As you write your essays, keep in mind that each paragraph should have a clear and coherent theme or argument expressed in a single sentence. This means that every paragraph should include one topic sentence that expresses this main idea. The other sentences within the paragraph should support or develop this topic sentence.
