The word "dean" traces back to the Latin decanus, meaning "leader of ten," originally referring to a military officer overseeing ten soldiers. In medieval times, it evolved to denote ecclesiastical and academic leaders, reflecting hierarchical organization (e.g., a dean supervising ten monks or scholars). The term retained its core sense of authority while shifting to educational and religious contexts.
