Forms

preux (feminine preuse, masculine plural preux, feminine plural preuses)[1] Old French proz, pros, pruz, preuz (nominative), prou, preu (oblique); preux from about 1382.[2][3][4][5]

Etymology

It is inherited from Old French proz, inherited from Late Latin *prōdis,[2][4][6][7] an adjective formed on Late Latin prōde (“useful, profitable”), attested from the 4th century in “prode est”, a wrong division of prōdest (“it is useful”), third person of Latin prōsum (“to be useful”), made on the model of “pote est” beside “potest”.[2][6][3][8] The neuter prōde also gave Old French preu (“profit”), surviving in prou.[2][6][1]

Compare Old Occitan pros and Italian prode.[2][6]

Earliest recorded meaning

The Chanson de Roland (about 1100) has the famous line “Rollant est proz e Oliver est sage”, Roland is brave and Oliver is wise.[9][5][10]

Semantic evolution

The original idea of usefulness underlies all its uses:[2] of things it meant good, of good quality,[2][5] and of people it specialised in the language of chivalry as “valiant”, synonymous with vaillant.[9][2] As a noun un preux is a hero of chivalry; the Neuf Preux, the Nine Worthies, appear about 1382.[9][4]

The word is now literary or archaic, used of medieval knights.[10][4] Derivatives are prouesse (about 1080) and the compound prud'homme “wise and loyal man”, later a member of an industrial tribunal (1806), whence prude.[6]
