lētum n (genitive lētī); second declension[1]
Etymology
It is inherited from Proto-Italic *lēto-, perhaps inherited from Proto-Indo-European *leh₁-to-, a participle “let go” used as a noun, “letting go”, then “death”.[2][1] It would then be the same formation as Slavic *lěto “summer, year”, as in Russian лето (leto, “summer”), from “going”.[2] Other proposals connect *ley- “to flow” or *lewH- “to loosen”.[1] Varro and Festus derived it from Ancient Greek λήθη (lḗthē, “forgetting”), whence the spelling lēthum.[3]
Earliest recorded meaning
De Vaan and Köbler date it from Plautus, whose soldier threatens to kill himself, cōnsciscam lētum.[2][4][5] Ennius has many meeting death.[5] Köbler dates Plautus c. 250–184 BC and Ennius 204–169 BC.[4]
Semantic evolution
It was death, usually violent, and a manner of dying, as Cicero's “see what a shameful death we are dying”.[5] In poetry it was death and destruction, as Lucretius' door of death not closed to the sky.[5] Döderlein says mors is death as a physical fact and lētum death as fate, the more solemn and poetic word.[6]
In Medieval Latin it was criminal jurisdiction over homicide, mortmain, and the death of the soul.[7] The adjective lētālis, spelled lēthālis in Late Latin, gave English lethal in the 1580s.[8]
