A dissertation is a lengthy and formal written work that presents original research on a specific subject, typically submitted as part of a doctoral degree. It involves extensive study and demonstrates a student's ability to conduct research and synthesize information in their field of study.
The word "dissertation" comes from the Latin "dissertatio," which means "discussion," derived from "dissertare," meaning "to discuss." The root "dis-" implies separation or distinction, while "sert" means to join or connect.
