A document that shows someone has completed a course of study or earned a degree from a school or university.

Diploma → It is derived from the Greek word "diplōma" (meaning folded paper or document), which comes from "diploun" (meaning to double or fold). The term originally referred to a document that was folded, indicating its importance and authenticity. In modern usage, it signifies a certificate or document awarded upon completion of a course of study.
Think of a 'folded document' ('diplōma') that signifies achievement — that's why a diploma is a certificate of accomplishment.
