Pronunciation

  • Classical: [kɫaː.rɪˈtuː.doː][1]
  • Ecclesiastical: [kla.riˈtuː.do][1]

Forms

clāritūdō f (genitive clāritūdinis); third declension[1]

Etymology

It is from Latin clārus (“clear, famous”) + -tūdō.[2][1][3] The adjective clārus goes back to Proto-Italic *klāros (“loud”) and Proto-Indo-European *kl̥h₁-ró- (“loud, sonorous”), from the root Proto-Indo-European *kelh₁- (“to call”); the shift from “loud” to “clear, bright” is also seen in Old High German hel (“loud”).[3][1]

Earliest recorded meaning

De Vaan and Köbler date it from Cato,[3][4] who speaks of “the greatest glory and the highest renown”.[2]

Semantic evolution

It is a by-form of clāritās.[5][6] Its usual sense is distinction or fame: Sallust uses it a few times and Tacitus very often, but it is not found in Cicero, Caesar, Quintilian or Suetonius.[5] The literal sense, brightness, is rare, as in Tacitus' brightness of the moon goddess; inscriptions on eye salves use it of clear vision, and Gellius of the clearness of an actor's voice.[2][5]

Timeline

  • 234–149 BC – Cato of renown.[2][3][4]
  • 86–34 BC – Sallust of fame.[5][4]
  • 98–115 AD – Tacitus, who uses it very often, also of the moon's brightness.[2][5][4]
  • c. 165 AD – Gellius of the clearness of a voice.[2][4]
