jurer[1]

Etymology

It is inherited from Old French jurer, inherited from Latin iūrō (“to swear, take an oath”), from iūs (“law, right”), in its original sense of a ritual formula with the force of law.[2][3][4][1][5] The same Latin family gave juge, juste, injure and conjurer.[6]

Cognate with Italian giurare, Old Occitan jurar, Spanish jurar, Portuguese jurar and Romanian jura.[6][7]

Earliest recorded meaning

The Strasbourg Oaths (842) have sagrament que son fradre Karlo iurat “the oath that he swears to his brother Charles”.[2][3][8]

Semantic evolution

In the Chanson de Roland it means to promise by oath, to take God as witness, to promise in marriage and to vow firmly: Guenes li fels ad nostre mort juree “the traitor Ganelon has sworn our death”.[2][3] Invoking sacred names profanely, cursing, is found in Wace (1160–74), whence juron (1599).[2][9] Losing the idea of an oath, it came to mean to affirm strongly (Pathelin, 1461–69): je n'en jurerais pas and il ne faut jurer de rien (1656), ne jurer que par (1668), jurer ses grands dieux (1690–1713).[2][3] From the violence of oaths came the sense “to clash”, first of discordant sounds (Boileau, 1665) and then of colours (1688).[2][3]
