A thesis, also known as statement thesis, is a one- to two-sentence statement that expresses the main idea of a giving paper. It is commonly used whenever the writer is trying to explain something to the reader or he/she is trying to persuade him to agree with his/her opinion. It usually comes within the introductory paragraph, in order to prepare the reader to listen to the author’s ideas, which will be developed later with reasons, explanations, evidence, and examples.
Some of the main key features of an argumentative thesis statement are:
• Debatable, an argumentative thesis must make a claim about which reasonable people could disagree.
• Assertive, an argumentative thesis takes a position, asserting the writer’s posture.
• Reasonable, an argumentative thesis must make a claim about something which is logical and possible.
• Evidence Based, an argumentative thesis must be able to be supported by evidence.
• Focused, an argumentative thesis must be focused and narrow.
