Every essay should have a reasoned argument that you use your paper to prove. This thesis statement should make a definite and limited assertion that requires further explanation and elaboration and indicates the emphasis of your paper and your position about the subject.
In 1-2 sentences, the thesis statement outlines the central purpose of your essay. A strong thesis expresses your conclusion about the subject (to be addressed and debated in the rest of the paper).
TIP: Place your thesis statement in the first paragraph so the reader can understand the purpose of your paper or essay.
Use of secondary statements, narrowing the focus of the thesis, will make it clear to any reader that you are aware of disagreements among scholars and experts concerning the subject. Evidence of others can support your ideas and help you refute the views of those who disagree with your thesis.
To give your paper a sense of direction, you will want to use broad statements at the outset and gradually narrow the focus, progressing from the general to the specific.
The focus of your paper should evolve as your research progresses. As you uncover new information and alter your opinion on the subject, feel free to revise your thesis.
