Pronunciation

  • IPA (Classical): [ˈfruːs.traː][1]
  • IPA (Ecclesiastical): [ˈfrus.tra][1]

Forms

frūstrā (not comparable)[1] Plautus scans frustră in the phrase nē frustrā sīs.[2]

Etymology

It is related to fraus “deceit, harm”.[2][3] De Vaan takes it as the plural of ⟨*frūstrum⟩, from ⟨*fraud-tro-⟩; he reconstructs ⟨fraus⟩ as Proto-Italic ⟨*frawV-⟩, perhaps from Proto-Indo-European *dʰrewgʰ- (“to deceive”), with Sanskrit ध्रुति (dhrúti-, “deception”) as a cognate.[4] Lewis & Short took it for an old case form of an adjective ⟨*frūsterus⟩, and Pedersen connected it with frustum “piece”.[5][3]

Earliest recorded meaning

The OLD's earliest citation is Plautus, “in vain”.[2] Köbler dates Plautus c. 250–184 BC.[6]

Semantic evolution

It meant to no purpose, in vain, without effect, as in Plautus, and in Terence without reason, needlessly, mistakenly, often in litotes.[2]

In Ecclesiastical Latin it means in vain, uselessly.[7] Medieval Latin used it for without reason, inconsiderately, and for with impunity.[8]

Timeline

  • c. 250–184 BC – Plautus uses it.[2][6]
  • 190–159 BC – Terence uses it of acting without reason.[2][6]
