The document provides guidance on writing an effective thesis statement. An effective thesis has two parts: it presents the paper's limited subject and the author's point of view about that subject. Examples of effective theses are given that use comparison/contrast, illustration, and cause/effect structures. The thesis should establish a tone and avoid being too opinionated, an announcement, or a factual statement. An implied pattern of development like compare/contrast should be included. The thesis is typically located in the introduction but may be delayed if needed.
