Pronunciation

  • Classical: [deːˈsɪ.pi.oː][1]
  • Ecclesiastical: [deˈs̬iː.pi.o][1]

Forms

dēsipiō (present infinitive dēsipere, perfect active dēsipuī); third (-iō variant) conjugation, no passive, no supine stem[1] The grammarian Charisius prescribes dēsipere, not dēsipīre.[2] The perfect dēsipuī is found in Lactantius.[3]

Etymology

It is from Latin dē- + sapiō (“to be wise”).[4][1][2] De Vaan traces sapiō to Proto-Italic *sap-i- and Proto-Indo-European *sh₁p-i- (“to notice”).[5] Cognate with Oscan sipus (“knowing”).[5]

Earliest recorded meaning

Plautus has it with a genitive, desipiebam mentis, “I was out of my mind”.[3]

Semantic evolution

It means to be out of one's mind, to lose one's reason,[4] and more generally to be silly or act foolishly:[3] Cicero speaks of saying that the greatest men are foolish, raving and mad.[3] Lucretius uses it of lacking rational intelligence: men would be without reason, and wild beasts would have it.[4] Horace's dulce est dēsipere in locō, “it is sweet to be foolish at the right time”, means to indulge in trifling.[3] Celsus uses it of a fever patient who is delirious.[3] Tertullian uses it once actively, to make insipid.[3]
