Pronunciation

  • IPA (Classical): [mɔrˈtaː.lɪ.taːs][1]
  • IPA (Ecclesiastical): [morˈtaː.li.tas][1]

Forms

mortālitās f (genitive mortālitātis); third declension[1]

Etymology

It is from mortālis “mortal” with the suffix -tās; ⟨mortālis⟩ is from mors “death”.[2][1][3] De Vaan traces ⟨morior⟩ “to die” to Proto-Indo-European *mr̥-yé- (“to die”).[4]

Earliest recorded meaning

Köbler's earliest source is Cicero, whom he dates 81–43 BC, and the OLD's first citations are from Cicero.[5][2]

Semantic evolution

It was the condition of being mortal, mortal nature, as in Cicero, and mortālitātem explēre was to die; and death as the natural end of life, as in Seneca.[2][6] Lewis & Short call it rare but classical.[7]

In Medieval Latin it was a pestilence, high mortality, a slaughter, and the right to receive bequests, and Köbler records mortālitās sacra, the plague.[8][5] English mortality (mid-14th century, “being subject to death”) came through Old French and directly from Latin.[3]

Timeline

  • 81–43 BC – Cicero uses it.[2][5]
  • 4 BC–65 AD – Seneca uses it of death.[2][5]
  • mid-14th century – English mortality is recorded.[3]
