The thesis is one of the most important concepts in college expository writing. A thesis sentence focuses your ideas for the paper; it's your argument or insight or viewpoint crystallized into a sentence or two that gives the reader your main idea. It's not only useful for the reading audience to understand the purpose of the essay, it's also useful for you as a writer, as it indicates the type of support that will follow in the paper and it may indicate a logical structure or order for that support. So...you need to have a good grasp of the concept of thesis in order to proceed.
The thesis identifies two basics:
There are two parts to a thesis sentence that reflect these basics.
Do you understand the basic topic and angle concept? If so, then there are a few more things to consider about the thesis. (And if not, now's the time to start asking the tutor!) It's important to investigate additional thesis characteristics at this point to make sure that you'll be creating working thesis sentences that actually are workable and appropriate for college essays. So in addition to knowing what a thesis is, you need to know what a thesis is not. A thesis sentence's angle should NOT be:
Once you create a working thesis, you should assess it to make sure that it fulfills thesis characteristics. Make sure it has a clear topic (indication of what the thesis is about) and angle (what your own ideas are about the topic). Make sure that the angle is not too broad, too narrow, a statement of fact, or an announcement. Work with the angle to make it indicate the order of your support, if you choose to do that for yourself or for your reading audience. And realize that the thesis is a working thesis until you finalize the essay (it's o.k. to revise the thesis as you go along just as long as you retain important thesis characteristics.)
