Pronunciation

  • Classical: [riːˈsɪ.bɪ.lɪs][1]
  • Ecclesiastical: [riˈs̬iː.bi.lis][1]

Forms

rīsibilis (neuter rīsibile); third-declension two-termination adjective[1]

Etymology

It is formed from Latin rīdeō (“to laugh”) + -bilis.[1][2][3] The adjective belongs to Late Latin.[1][4]

Earliest recorded meaning

Its earliest dated use is in Eustathius' Latin version of the Hexaemeron (c. 400 AD), in the sense “laughable”: quid his risibilius fieri potest? “what could be more laughable than this?”[3][5][6] Martianus Capella uses it for the human ability to laugh: unus homo risibilis “man alone can laugh”.[2][5]

Semantic evolution

Late Latin used it in two ways, actively of a being that can laugh and passively of what deserves laughter;[3][7][8] Cassiodorus has the neuter plural for ridiculous ceremonies.[3][7][8]

Medieval philosophers took over Martianus' definition: homo est risibilis became a stock example in logic, and the neuter risibile was used as a noun for the faculty of laughing.[4] The word also kept the sense “ludicrous, absurd” and could mean “jocular, comical”.[4] French, Italian, Spanish and English borrowed it,[1] English first as “given to laughter” in the 1550s.[9]

Timeline

  • c. 400 AD – Eustathius uses the comparative risibilius “more laughable”.[3][5][6]
  • c. 485–c. 580 AD – Cassiodorus writes of risibilia, ridiculous rites.[3][7][6]
  • 1410 – An Oxford formulary speaks of animals that can laugh.[4]
  • 1550s – English borrows it as risible, from French and directly from Late Latin.[9]
