Thesis statements establish the focus and purpose of an essay. Further, they take a stand instead of announcing a subject.
Your thesis statement should appear at the end of the first paragraph of your essay.
Think of your thesis statement as something you need to prove or an argument you intend to win.
A thesis statement has one main point instead of several main points. More than one point might be too difficult for the reader to understand and the writer to support.
To make your topic into a thesis statement, you need to make a claim about it. You want to persuade readers to see your way of thinking.
