Thesis Statements
A strong thesis statement is a map that you provide for your reader to follow. It works
as a guide to what is most important to understand about your writing, and it can serve
as an outline to follow as you write. A strong thesis statement is composed of three
parts: the What, the What About It, and the Why.
WHAT:
o This is the subject of the sentence and the basis of your topic.
o The What should open the sentence as the clear subject.
o State the full name of the What, avoiding pronouns.
For example: Because of its benefits, it should be legal.
Instead: Medical marijuana must be legalized for its medicinal properties, its
implications to our legal system, and to our economy.
WHAT ABOUT IT:
o This is your position on your topic, your argument, or what you will prove.
o The What About It should clearly state the purpose of your paper.
o As the action of the statement, it should follow the subject.
For example: Because of its benefits, it should be legal.
Instead: Medical marijuana must be legalized for its medicinal properties, its
implications to our legal system, and to our economy.
WHY:
o This is the significance of your argument, why you have chosen your
position, how you will prove it, or what supporting evidence will be shown.
o The Why can work as an outline for your body paragraphs.
o Specify all of your main points, and try to present them in order.
For example: Because of its benefits, it should be legal.
Instead: Medical marijuana must be legalized for its medicinal properties, its
implications to our legal system, and to our economy.
Ø Consider the type of paper assigned (Analytical, Argumentative, Expository,
Reflective, Research, etc.) and any specific advice about how your professor
may prefer thesis statements.1
Ø Finally, revise your thesis as you develop the ideas in your paper. It’s written on a
word processor, not in stone. You are allowed to change your mind.
