From PurdueOwl.com: “Circular Argument: This restates the argument rather than actually proving it. Example: George Bush is a good communicator because he speaks effectively. In this example, the conclusion that Bush is a "good communicator" and the evidence used to prove it "he speaks effectively" are basically the same idea. Specific evidence such as using everyday language, breaking down complex problems, or illustrating his points with humorous stories would be needed to prove either half of the sentence.”
