The word Fallacy is a derivative of the Latin word fallacia, which meant to trick or be deceptive. The word Fallacy in modern English means to make an error in reasoning, or a false inference. Fallacy refers to a broad category that encompasses individual kinds of fallacies, of which there are many different types. Errors in reasoning can usually be placed within these individual categories, and identified by the nature of the error itself. How the reasoning was faulty determines the category of fallacy in which the error is placed, and identifies the fallacy type.
