What is a Thesis Sentence?
A thesis sentence is the summary of the main points in a research paper or a thesis. It is a single sentence that is usually in the conclusion of the introductory paragraph. It helps to develop and organize the body of the thesis. It also contains the controlling idea of an essay and maintains its unity. Through this sentence, the opinions and the judgements of the writer too can be identified.
There are two types of thesis sentences: explanatory and argumentative. An explanatory sentence mentions the subject, whereas an argumentative sentence is a claim that the readers may agree or disagree with.
