Etymology

janitor = jani<door> + tor<agent suffix>

  • jani (from Latin ianua meaning "door")
  • tor (Latin agent suffix indicating "one who does," akin to -or in "actor")

Etymology Origin:
The word "janitor" traces back to Latin ianitor, derived from ianua (door). In Roman mythology, Janus was the two-faced god of doors, gates, and transitions—symbolizing beginnings and endings. The term originally referred to a doorkeeper, reflecting Janus’s role as a guardian of thresholds. Over time, its meaning shifted to denote a caretaker of buildings, emphasizing maintenance over guardianship.
