Definition: Thesis statement
A thesis statement is a statement of position.
In university writing, it is typically a sentence or two which establishes your argument and forecasts the main points your paper will argue. It is the backbone of your paper, because everything that goes after should support this central argument. A thesis has to be arguable/contestable and cannot be a statement of fact.

Why the thesis statement is significant
Your thesis statement is where your reader can look to find out what a paper is about, and why and how the topic will be addressed. It is where the topic, or more specifically the argument, is narrowed and focused. In addition, theses are often tied to the “roadmap” of the paper. That is, an explanation of the subarguments and structure that you will use to prove your overall thesis.
Using your thesis statement to structure your paper
The very first aim of a thesis statement is to establish a position, the 2nd is to explain how that position will be argued. That means explaining subarguments that will support the overall position of your paper. These subarguments will then become sections of your paper.

Forming your thesis statement
There are many different ways to structure a thesis statement, however, the following are some basic instruments and diagrams to help in developing your framework for your thesis.
In general, a thesis statement has three basic components, and can be visualized like this:
The following questions can be used to develop each component:
Context (or topic)
What are you talking about? What is the issue you are discussing?
Position (or argument)
What is your position on your topic? What do you think?
For a comparison or synthesis paper, a Venn diagram can help determine the relationship inbetween the two things being compared. Once a relationship is determined, it can become the position of your thesis, because you are arguing that this relationship exists on the basis of x, y and z.
Reasoning (your x, y, and z)
Why should your reader believe you? What supports your position and proves your argument?
