Pronunciation

  • Classical: [apˈsʊr.dɪ.taːs][1]
  • Ecclesiastical: [abˈsur.di.tas][1]

Forms

absurditās f (genitive absurditātis); third declension[1]

Etymology

It is formed from Latin absurdus (“out of tune; senseless”) + -tās.[2][3][4] The adjective is made of ab- and surdus (“deaf”); since “deaf” can mean both “who cannot hear” and “who is not heard”, de Vaan explains absurdus as “unheard of”.[5]

Earliest recorded meaning

Augustine is its first author, using it of things that make no sense, in the plural as well.[6][3]

Semantic evolution

Priscian used it of a discordant sound, the literal sense of its base,[7][8][9] and Claudianus Mamertus has it too.[2] It was mostly a word of Christian writers, Augustine above all.[7][10]

In medieval Latin it meant a musical dissonance as well as unreasonableness;[11] British sources have both senses, the second of the excesses of certain religious in a letter of 1300.[12] Leonardo Bruni spoke of the absurdity of a translation.[10] English borrowed it in the late 15th century as absurdite,[4] and Conte derives Italian assurdità from the Late Latin word.[9]

  • 354–430 AD – Augustine uses it for an absurdity.[6][3]
  • first half of the 5th century AD – Claudianus Mamertus uses it.[2][3]
  • 6th century AD – Priscian uses it of a discordant sound.[7][6][3]
  • 1300 – A letter in the Canterbury registers speaks of the absurditates of certain religious.[12]
