The word "janitor" refers to a person who is responsible for the cleaning and maintenance of a building, such as a school, office, or other facility. Janitors often perform tasks like sweeping, mopping, dusting, and emptying trash cans. They may also take care of minor repairs and ensure that the environment remains safe and organized.
The word "janitor" originates from the Latin word "janitor," which means "doorkeeper." This is derived from "janua," meaning "door." Over time, the term evolved to refer more broadly to someone who maintains and cares for a building.
