Thesis (plural: theses, pronounced THEES-eez): The point that an essay is trying to prove. Also known as the claim or argument. Everything in a persuasive essay relates to the thesis, either as evidence, explanation, elaboration or rebuttal of alternative claims. Think of the thesis as the spine of your paper. Just as all the parts of your body are connected to the spine, and without the spine your body could not stand, so too in your essay all parts must be connected to the thesis, and without the thesis the essay cannot stand.
