Keep in mind that the main importance of an essay is to provide basic background on a subject and, hopefully, to spark enough interest to induce further reading.
A true friend will be there for you whenever you need them.
The writer may next ask what characteristics dogs have that make them true friends.
Each characteristic may be the topic of a body paragraph.
They will enter and depart from our existences as matters of mutual convenience. This shaped the topic and narrowed the focus to dogs as friends.
This would make writing the remainder of the essay much easier because it allows the writer to focus on aspects of dogs that make them good friends. If the thesis contains multiple points or assertions, each body paragraph should support or justify them, preferably in the order the assertions originally stated in the thesis.
The introductory paragraph accomplishes three purposes: it captures the reader’s interest, it suggests the importance of the essay’s topic, and it ends with a thesis sentence.
Often, the thesis sentence states a claim that consists of two or more related points.
Not all thesis sentences will, or should, lay out each of the points you will cover in your essay.
In the example introductory paragraph on dogs, the thesis sentence reads, “There is no friend truer than a dog.” Here, it is the task of the body paragraphs to justify or prove the truth of this assertion, as the writer did not specify what points they would cover.
