Pronunciation

  • Classical: [fruːsˈtraː.tʊs][1]
  • Ecclesiastical: [frusˈtraː.tus][1]

Forms

frūstrātus m (genitive frūstrātūs); fourth declension[1]

Etymology

It is from Latin frūstror (“to deceive, frustrate”) + -tus3.[2][3][4] The verb is formed from frūstrā (“in vain”), which de Vaan takes as the plural of an unattested *frūstrum from *fraud-tro-, built on fraus (“deceit”).[5]

Earliest recorded meaning

It is found only in Plautus,[5] in the Menaechmi: a woman tells a man who keeps fooling her to find another woman to make sport of (“aliam posthac invenito quam habeas frustratui”).[3][4]

Semantic evolution

The noun stayed rare: after Plautus, Symmachus uses it in a letter,[4] and Nonius Marcellus has it of mime actors who are a laughing-stock to everyone.[4]

Timeline

  • c. 250–184 BC – Plautus uses the dative frustratui in the Menaechmi.[3][4][6]
  • c. 340–402 – Symmachus uses it in a letter.[4][6]

Meanings

Noun

  1. Deception, delusion;[2][3][4] habere aliquem frustratui, to make a fool of someone.[2][3][4]

Usage notes

The form is also the perfect participle of frūstror, which was used as an adjective meaning “vain, useless” from Manilius on.[4]
