Topic Sentence, Main Idea, or Thesis Statement

A Topic Sentence appears in every good piece of writing. It’s about the writer’s perspective on the subject or what the writer intends to convey to the readers about the subject. The writer expresses the primary argument through a Topic Sentence (for a paragraph) and a thesis statement (for an essay). Let’s look at the link between an essay’s thesis statement and the topic sentences that reinforce it in a paragraph.

The main idea often occurs in the first or last sentence of a paragraph. In essays, for example, the thesis statement is frequently one phrase long. It also comprises many more phrases relating to the Topic Sentence (typically the first or last) in an opening paragraph.

Topic Sentence vs Thesis Statement

A paragraph’s topic sentence is substantially shorter than an essay’s thesis statement. Because a paragraph is shorter, it allows for fewer ideas to be developed. An essay, on the other hand, is longer, with multiple paragraphs and a variety of in-depth material. There are numerous essential characteristics of a good Topic Sentence or Thesis Statement. Because it provides readers with particular information that allows them to understand the writer’s main argument.

Basics of Supporting Details

The collection of instances, facts, or information that supports a statement is referred to as supporting details. They demonstrate, explain, or prove the whole point in various ways, depending on what we’re reading. Primary support points are the core concepts that support your main argument, while Secondary support provides information to assist your primary support. So, to support the primary point, the author may offer statistics, facts, definitions, and scientific results. For example, the author draws on personal experiences, recollections, anecdotes, analogies, expert quotes, and personal observations.


First, consider these unsupported statements:

  • My bill has an erroneous amount on it.
  • I am deserving of a raise.
  • I am not guilty of the crime.

The claims may be genuine, yet they lack credibility since they are not backed up by evidence.


My bill has an erroneous amount on it. The Biryani Rice Plate, which costs $6.99 on the menu, was what I ordered. The order is right on the bill, however, the total is $16.99.
