Pronunciation

  • IPA (Classical): [ˈjak.toː][1]
  • IPA (Ecclesiastical): [ˈjak.to][1]

Forms

iactō (present infinitive iactāre, perfect active iactāvī, supine iactātum); first conjugation[1]

Etymology

It is a frequentative of iaciō “to throw” with the suffix -tō.[2][1][3][4]

Earliest recorded meaning

The OLD's first citation is Ennius, of hurling.[2] Köbler dates Ennius 204–169 BC.[5]

Semantic evolution

It meant to throw, hurl, as Cicero's men scattering palm roots, to cast a net or dice, to toss about, and to throw away, jettison cargo, as in Livy.[2][6] It meant to wave, brandish, as in Cato, to fling the body about, and of the sea to toss ships to and fro, as in Plautus, figuratively to harass.[2] It meant to hurl words, to discuss freely, and to boast of, as in Caesar, reflexively to brag, show off, and with an ablative to pride oneself on, as in Cicero.[2]

Spanish and Portuguese jactar “to boast” are borrowings.[1] Late Latin iectāre, which replaced it, gave French jeter “to throw”, whence English jet in the 1690s.[4]
