A thesis (plural: 'theses') is a document written in support of an idea that is presented for discussion or disputation. In modern usage it usually refers to a document presented as a requirement for an academic degree or professional qualification. It presents the author's research and findings. In the academic context it means the same as dissertation. The term dissertation can be used to describe an argument without relation to academic degrees. The term thesis may also be used for the central claim of an essay or other work.
