Pronunciation

  • Classical: [ˈsoː.pi.oː][1]
  • Ecclesiastical: [ˈsɔː.pi.o][1]

Forms

sōpiō (present infinitive sōpīre, perfect active sōpīvī or sōpiī, supine sōpītum); fourth conjugation[1]

Etymology

It is inherited from Proto-Indo-European *swep- (“to sleep”), the root of somnus (“sleep”), but how the verb was formed is disputed.[1][2] The LIV reconstructs Proto-Indo-European *swṓp-ye-ti, which de Vaan doubts as a type;[1] Nussbaum proposed a verb made from a root noun, and Vine a present Proto-Indo-European *swṓp-eye-ti.[1] The OLD compares Sanskrit स्वापयति (svāpáyati).[2]

Earliest recorded meaning

Lewis & Short quote Ennius' “I put to sleep the fierce dragon's attack”.[3][2]

Semantic evolution

It means to put or lull to sleep, most often in the perfect participle;[2][3] Cicero uses only the participle, of the mind awake while the body sleeps.[2][3] Lucretius uses it of a woman sent to sleep by castoreum and of death, as Homer “laid to rest in the same sleep as the others”.[3] It also means to knock someone senseless, as Livy's king stunned by a sudden blow, or to stupefy with wine.[2][3] In the poets it can mean to kill, as in Silius.[3] Of things it is to calm or settle, as Pliny the Elder's winds put to rest, and Virgil's embers revived from sleep.[3] Church Latin glosses it “lull to sleep”.[4]
