Pronunciation

Forms

juré m (plural jurés, feminine jurée)[1] Anglo-Norman also joré, jouré and jureis.[2]

Etymology

It is inherited from Old French juré, inherited from Latin iūrātus (“one who has sworn, sworn man”), the past participle of iūrō (“to swear”).[3][4][1] The Medieval Latin noun iūrātus meant a man who had sworn fidelity (late 11th century).[3] From 1127 the charters granted to the towns of northern France used it for councillors bound by an oath to the lord.[3][5] The word merged with the past participle of jurer.[5][6] The sense “member of a jury” is a rendering of English, after jury and probably juryman.[3][5] The Latin word was later borrowed as jurat, a doublet.[1]

Earliest recorded meaning

Its first record, in the Lai du cor (late 12th century), is a man who has sworn fealty to the king, a vassal.[3][5]

Semantic evolution

About 1200 it named a member of a town council who, under oath, held from the lord the powers of administration and justice.[3][5] From 1260 (Étienne Boileau's book of trades) a juré was a master or journeyman sworn to watch over a trade; hence maître juré, used jokingly by Molière in maître juré filou (1668).[3][5][7] The adjective is figurative in ennemi juré “sworn enemy”, from 1580 (Montaigne).[5][7]

The modern sense, a member of the jury of a court, is first used of England (les douze hommes jurez, 1588) and was adopted for France with the Constitution of 1791, when juré could mean both a juror and the jury itself.[3][5][6]
