Pronunciation

  • Classical: [au̯.diːˈtoː.ri.ʊs][1]
  • Ecclesiastical: [au̯.diˈtɔː.ri.us][1]

Forms

audītōrius (feminine audītōria, neuter audītōrium); first/second-declension adjective[1]

Etymology

It is from Latin audītor (“hearer”) + -ius,[2][3] which Wiktionary analyses as audiō (“to hear”) with the suffix -tōrius.[1] The verb goes back to Proto-Italic *awizdje/o- (“to hear”), which de Vaan explains as Proto-Indo-European *h₂eu-is (“clearly”) combined with a verb meaning “to render”.[4]

Earliest recorded meaning

Its earliest record is in the medical writer Vindicianus,[5] of the 4th century AD,[6] who speaks of fluid passing through the auditoriae cavernae, the passages of the ear.[5]

Semantic evolution

As an adjective it is rare: Lewis & Short know it only from Caelius Aurelianus, again with cavernae for the auditory passages.[2][7] The neuter used as a noun, audītōrium, was far more frequent.[2]

In Medieval Latin it meant both “listening” (a listening crowd) and “belonging to the sense of hearing”, as in the anatomical term for the auditory nerve.[8] English borrowed it as auditory in the 1570s.[3]

Timeline

  • 4th century AD – Vindicianus writes of the auditory passages of the ear.[5][6]
  • 5th century AD – Caelius Aurelianus uses the same phrase in a chapter on earache.[5][6]
  • 1570s – Borrowed into English as auditory.[3]

Meanings

Adjective

  1. Relating to hearing or to a hearer; auditory.[2][7][9]
  2. (Medieval Latin) Listening, made up of hearers.[8]

Usage notes
