Pronunciation

  • Classical: [ˈoːs.kɪ.toː][1]
  • Ecclesiastical: [ˈɔʃ.ʃi.to][1]

Forms

ōscitō (present infinitive ōscitāre, perfect active ōscitāvī, supine ōscitātum); first conjugation, no passive[1]

Etymology

It is from Latin ōs1 (“mouth”) + citō2 (“to set in motion”),[1][2] though the OLD gives this only as likely;[3] the TLL thinks that ⟨ōs⟩ and ⟨citāre⟩, used side by side, grew together.[4] De Vaan lists it among the derivatives of the word for “mouth”,[5] and Georges connects its second part with cieō (“to move”).[2] The noun goes back to Proto-Italic *ōs- and Proto-Indo-European *h₃eh₁-os (“mouth”).[5]

The grammarian Nonius explained it instead from ⟨citum⟩, “divided, separated”.[4]

Earliest recorded meaning

De Vaan dates it from Plautus,[5] who uses the deponent form in the Menaechmi of a man thought to be mad, stretching himself and gaping.[3][6]

Semantic evolution

Its first sense is “to open the mouth wide, gape”, and it was also said of things that open out: Ennius has a head torn from the neck gaping on the plain, Columella the flower called the lion opening, and Pliny the Elder leaves that open towards the sun every day.[3][6][2]

More often it means “to yawn” from weariness or boredom: Cicero has a juror yawning while the speaker talks, and Epicurus' teachings as the dreams of a yawning man;[3][6] Lucretius describes a man who yawns as soon as he reaches his villa;[3][6] Gellius has a man who yawned loudly while standing in court.[3][6] Figuratively it meant to sit idle: the Rhetorica ad Herennium reproaches people who sit and yawn while worse disasters threaten.[3][6][2] Persius and later Augustine use it with an object, of yawning off the night's drinking.[3][6]

The present participle ōscitāns came to mean “listless, careless”: Terence has people caught off guard, and Cicero speaks of the drowsy wisdom of the Scaevolas; he also has the adverb ōscitanter, “carelessly”.[6][2] The deponent ōscitor appears in Plautus, Turpilius, the Rhetorica ad Herennium and Seneca.[3][4]

English took oscitate from its past participle in the 1620s.[7]
