Definition of the word dean

The term "dean" originated from the Latin word "decanus," which means "of ten." In the early Christian Church, a dean was a official responsible for a group of ten churches or a specific region. The term evolved from the Latin "decem," meaning "ten," and the suffix "-anus," indicating a relation or pertinence. In the 10th century, the term "dean" was used in the English-speaking world to refer to the head of a cathedral chapter or the chief administrative officer of a collegiate church. The dean was responsible for the day-to-day management of the church and its affairs. Over time, the term has been adapted and expanded to refer to various titles and offices in education, such as the head of a college or university, or a high-ranking official in a professional organization.
