Pronunciation

  • Ecclesiastical: [inˈtɛr.ri.tus][1]

Forms

interritus (feminine interrita, neuter interritum); first/second-declension adjective[1]

Etymology

It is from Latin in- (“not”) + territus (“frightened”), the participle of terreō (“to frighten”).[2][3][1] De Vaan, following the LIV, traces terreō to Proto-Italic *tros-eje- (“to scare”) and Proto-Indo-European *tros-eie- (“to make scared”), comparing Umbrian tursitu (“to scare”), Sanskrit त्रसन्ति (trásanti, “they tremble”) and Ancient Greek τρέω (tréō, “to be scared, tremble”).[4]

Earliest recorded meaning

Lewis & Short's earliest examples are in Virgil, who has a man raising his arms undaunted and a fleet sailing on unafraid.[5][6]

Semantic evolution

It means undaunted or fearless, of people and animals, and in poetry of things such as a fleet.[2][5] Lewis & Short call it poetic and post-Augustan in prose, as in Quintilian's unflinching face.[5] Köbler gives Ovid as its first author.[6] Manuscripts often confuse it with interitus, destruction.[3]

Timeline

  • 70–19 BC – Virgil of a fearless boxer and fleet.[5][6]
  • 43 BC–18 AD – Ovid uses it.[6]
  • c. 35–95/96 AD – Quintilian of an unflinching face.[5][6]
