Pronunciation

  • IPA (Classical): [ˈriː.sʊs][1]
  • IPA (Ecclesiastical): [ˈriː.s̬us][1]

Forms

rīsus m (genitive rīsūs); fourth declension[1]

Etymology

It is from Latin rīdeō (“to laugh”) + -tus, an action noun.[2][1][3] De Vaan finds no good Indo-European etymology for ⟨rīdeō⟩ and rejects the old comparison with Sanskrit व्रीडते (vrīḍate, “is shy”).[4]

Earliest recorded meaning

The OLD's earliest citation is Plautus, of laughter.[2] Köbler dates Plautus c. 250–184 BC.[3]

Semantic evolution

It meant laughter or a laugh, as in Cicero's rīsum movēre “to raise a laugh”, and in Propertius by metonymy an object of laughter, a laughing-stock.[2][5][6] Apuleius has Rīsus as the god of Laughter.[6]

In Ecclesiastical Latin it means laughter.[7] It survives as French ris, Italian and Portuguese riso, Spanish risa and Romanian râs.[1]

Timeline

  • c. 250–184 BC – Plautus uses it.[2][3]
  • 81–43 BC – Cicero has rīsum movēre.[5][3]
  • 57/46–12 BC – Propertius uses it of a laughing-stock.[2][3]
