Pronunciation

  • Classical: [eː.rʊˈdiː.ti.oː][1]
  • Ecclesiastical: [e.ruˈdit.t͡si.o][1]

Forms

ērudītiō f (genitive ērudītiōnis); third declension[1]

Etymology

It is from Latin ērudiō (“to educate, instruct”) + -tiō.[2][1][3][4]

Earliest recorded meaning

Köbler dates it from Cicero,[4] who writes to his brother Quintus that there is nothing to say about his instruction, since Quintus knows his talent.[2][5]

Semantic evolution

The first sense is the action of teaching, instruction, but far more often it is the knowledge gained by instruction: learning, culture, or a branch of learning.[2][5] Cicero speaks of a man without any learning.[2] Döderlein distinguishes doctrina, learning as a particular kind of intellectual training, from ērudītiō, its learned result, the crown of intellectual cultivation.[6] Church Latin uses it of learning.[7] English erudition (c. 1400) first meant instruction.[8] Since the 1520s it has meant learning or scholarship.[8]

Timeline

  • 81–43 BC – Cicero of instruction and of learning.[2][4]
  • c. 1400 – English erudition, instruction.[8]
  • 1520s – English erudition, learning.[8]

Meanings

Noun

  1. The action of teaching, instruction.[2][5][1]
