Pronunciation

  • Classical: [ɪnˈdɔr.mi.oː][1]
  • Ecclesiastical: [inˈdɔr.mi.o][1]

Forms

indormiō (present infinitive indormīre, perfect active indormīvī, supine indormītum); fourth conjugation[1]

Etymology

It is from Latin in- + dormiō (“to sleep”).[2][3][1] dormiō goes back to Proto-Italic *dormje/o- and Proto-Indo-European *drm-i̯e- (“to sleep”),[4] and is cognate with Ancient Greek δαρθάνω (darthánō, “to fall asleep”).[4]

Earliest recorded meaning

The TLL finds it from Cicero on,[3][5] who uses it figuratively of someone asleep over a matter: in the Philippics he asks whether torches are needed to wake “you” as you sleep over so great a cause (tē tantae causae indormientem).[3][6]

Semantic evolution

Cicero also confesses to his brother that he has long been asleep over the task of cultivating a man,[3][7] and Pliny the Younger speaks of being roused from long idleness.[3][7] In the literal sense Horace has someone sleeping on sacks heaped up all around (congestīs undique saccīs indormīs),[2][6] and Petronius someone who fell asleep in another's embrace.[3][6] Curtius uses it of sleeping unaware of one's troubles, and a verse inscription says that fear never slept in a certain Heliades.[3]

In Vegetius' veterinary writings it meant to go numb, of a horse's jaw or shoulder.[3][7]
