A thesis statement is defined as a sentence that describes the topic and purpose of a paper. Students are usually expected to write good thesis statements. However, this only comes with learning and practice. According to the UAGC website, a good thesis statement will direct the structure of your essay and will allow your reader to understand the ideas you will discuss within your paper. The thesis should be located within the opening paragraphs of a paper. Often, the thesis is written as the last sentence of the introduction. Although a thesis is usually one sentence, it can be broken into two sentences for complex subjects. The nature of a thesis statement depends on the paper one is writing: argumentative thesis statement, analytical thesis statement, and Expository Thesis Statement.
