Pronunciation

  • Classical: [kuː.riˈoː.sɪ.taːs][1]
  • Ecclesiastical: [ku.riˈɔː.s̬i.tas][1]

Forms

cūriōsitās f (genitive cūriōsitātis); third declension[1]

Etymology

It is from Latin cūriōsus + -tās, the abstract noun of the adjective meaning “careful, inquisitive”.[2][1][3] The adjective belongs with cūra (“care, anxiety”); de Vaan reports Leumann's view that cūriōsus is a back-formation from incūriōsus.[4][5]

Earliest recorded meaning

Cicero uses it once, in a letter to Atticus, where he says sum in curiositate (“I am all curiosity”) and adds a Greek adjective.[6][7] The sense there is eagerness to know or find out.[2][8]

Semantic evolution

After Cicero the word is rare until Apuleius and Tertullian, from whom it becomes more frequent; the plural appears from Tertullian on.[6] The OLD defines it as an excessive eagerness for knowledge,[2] and the TLL notes that a sense of talkativeness sometimes goes with it.[6] Tertullian also uses it for a thing that excites curiosity,[9] and Augustine speaks of curiositates sacrilegas atque inlicitas, “sacrilegious and forbidden curiosities”.[3]

Medieval Latin added the older sense of its base, care and diligence: Alcuin's letters use the plural for concerns about the Catholic faith, and the DMLBS and Niermeyer give “care, anxiety”.[10][11] The MLW lists both a good or neutral and a bad sense of curiosity, levity, and in a passive sense trouble, extravagant elegance and superfluity,[12] and British sources use it for an oddity or an elaborate refinement.[10] The word passed into the Romance languages, as Italian curiosità,[9][1] and through French into English as curiosity.[13]
