erudition

Etymology

It is inherited from Middle English erudicioun,^[2][3] borrowed from Latin ērudītiō (“instruction, education, learning”),^[4][5][6][2] a noun of action from ērudiō (“to educate, instruct, polish”),^[4][5][7] which is formed from ē- (“out”) and rudis (“rough, untrained”), so that it means literally to bring out of the rough.^[5] The Shorter Oxford also gives Old French érudition as a possible source.^[7]

Earliest recorded meaning

The action of instructing; education.^[2][4] The Middle English Dictionary's first quotation, dated about 1450, is from Capgrave's life of St Augustine: He was not redy in langage to erudicion of þe puple.^[2] The OED's first record is in the Tale of Beryn, in a manuscript of about 1460, composed perhaps about 1400,^[4][2] and Etymonline dates the word to about 1400.^[5]

Semantic evolution

The word moved from the act of teaching to its result.^[4] It also meant what was taught, a doctrine or maxim (1528–67), and the state of having been trained or instructed (1530–1639).^[4][2] The sense of acquired knowledge, especially in languages, literature and antiquities, is recorded by the OED from 1718,^[4] although Etymonline dates "learning, scholarship" to the 1520s.^[5] Johnson (1755) already defines it as learning, knowledge obtained by study and instruction,^[8] while Henry Fielding could still use it for instruction.^[7] Addison, before 1719, applied it to the fine finish of a coin, a rare use.^[4] In Scots, as in Galt's Provost (1822), it meant politeness or courtesy.^[9] Merriam-Webster Unabridged now stresses deep knowledge gained chiefly from books.^[3]
