What does janitorial mean?
Janitorial is an adjective meaning connected with the cleaning, maintenance, and upkeep of a building or facility. It commonly describes the work performed by janitors or custodial employees, as in janitorial duties, janitorial staff, or janitorial services. The term can also refer more broadly to supplies and areas associated with routine building care, such as a janitorial closet. It is generally formal and practical rather than literary, and it is especially common in workplace notices, job descriptions, contracts, and institutional communications. Although it sounds narrow, the word covers a broad range of tasks, including cleaning, waste removal, basic repairs, and maintaining a facility in a safe and presentable condition. Janitorial ultimately comes from Latin janitor, originally a doorkeeper or guardian of a door, and its modern sense reflects the expansion of that role into general building maintenance.
