ianitor

Etymology and origin of the Latin word ianitor

History

Pronunciation

  • IPA (Classical): [ˈjaː.nɪ.tɔr][1]
  • IPA (Ecclesiastical): [ˈjaː.ni.tor][1]

Forms

iānitor m (genitive iānitōris); third declension[1]

Etymology

It is formed from iānus “arched passage, doorway” or from iānua “door” with the agent suffix -tor.[2][3][4] Iānus goes back to Proto-Italic *jānu- (“door”), from Proto-Indo-European *yeh₂-n-u- (“passage”), from the root of Sanskrit याति (yā́ti, “goes”).[3] Varro quotes an old form ianitos from the Salian hymn.[2][5]

Earliest recorded meaning

De Vaan and Köbler date it from Plautus,[3][6] who has a visitor knock and call “hey, is there a doorkeeper here? Open up!”.[7]

Semantic evolution

It meant a doorkeeper or porter, often a slave chained near the entrance, and also the keeper of a prison.[7][8] The TLL notes that the word is old but rare in form, that after Cicero it is mostly poetic, and that ostiarius and portarius took over in prose; it did not pass into the Romance languages.[5] Poets called Cerberus the ianitor of the underworld, and Ovid calls Janus the doorkeeper of heaven.[2][7]

In Christian usage the porter was the lowest of the holy orders, and Saint Peter was the doorkeeper of heaven.[9][6] English borrowed it as English janitor in the 1580s, first meaning an usher in a school, and later a caretaker of a building.[4]
