Here's why:
* Thesis statement: The thesis statement is a concise summary of the main point or argument of the essay. It acts as a roadmap for the reader, outlining the key idea that will be developed and supported throughout the essay.
* Central argument: The thesis statement encapsulates the central argument, providing a clear and focused direction for the essay.
* Claim: The thesis statement often presents a claim, a statement that can be argued for or against.
* Premise: The thesis statement can also be considered a premise, a statement that is assumed to be true and used as the starting point for the argument.
In short, the thesis statement is the heart of the essay, serving as the foundation for all the supporting evidence and analysis that follows.
