mors

Etymology and origin of the Latin word mors

Pronunciation

  • IPA (Classical): [ˈmɔrs][1]
  • IPA (Ecclesiastical): [ˈmɔrs][1]

Forms

mors f (genitive mortis); third declension[1]

Etymology

It is inherited from Proto-Italic *morti- (“death”),[2][1] from inherited from Proto-Indo-European *mr̥-tí- (“death”),[2][3] a noun formed from the root *mer- (“to die”), which also gave morior (“to die”) and mortuus (“dead”).[1][4][2]

Cognate with Sanskrit मृति (mṛti-) and Lithuanian mirtis.[5][6] Ancient Christian writers derived it from the bite (morsus) of the serpent that killed Adam, and Isidore of Seville from Mars, the bringer of death.[6]

Earliest recorded meaning

Its first author is Naevius,[2][3] and from early Latin on it means death, the act or fact of dying.[5]

Semantic evolution

Besides the act of dying, the word meant death as a state,[5] and death personified as a goddess, the daughter of Erebus and Night.[5][7] By extension it was used for annihilation or extinction, for a corpse, and for a means or cause of death, including a person who brings death to others.[5][7]

In the Vulgate the “second death” is the punishment of the damned,[7] and Death can stand for the devil, who held the power of death.[7] Medieval Latin used it for capital punishment, for manslaughter and for an epidemic or plague.[8][3]

  • c. 235–200 BC – Naevius is the first author to use it.[2][3]
  • c. 250–184 BC – Plautus calls on Death as a friend.[5][3]
  • 81–43 BC – Cicero lists Death among the offspring of Erebus and Night.[5][3]
  • 96–55 BC – Lucretius uses it for the annihilation of things.[5][3]
