Pronunciation

  • Classical: [ˈtɛr.rɪ.toː][1]
  • Ecclesiastical: [ˈtɛr.ri.to][1]

Forms

territō (present infinitive territāre, perfect active territāvī, supine territātum); first conjugation[1]

Etymology

It is from Latin terreō (“to frighten”) + -itō, a frequentative.[2][1] De Vaan traces terreō to Proto-Italic *tros-eje- (“to scare”) and Proto-Indo-European *tros-eie- (“to make scared”), comparing Ancient Greek τρέω (tréō, “to tremble, flee”).[3]

Earliest recorded meaning

Plautus has it first, in a question: why threaten him with death?[2][4]

Semantic evolution

It is to keep someone in fear, to try to scare: in Plautus a character says that he will not be scared by such words.[2][4] Of facts and conditions it means to strike lasting fear into someone.[2] Lewis & Short call it classical, though perhaps not used by Cicero.[4]
