He codified the French language for the aristocracy, turning the speech of the Parisian court into the nation's official standard.
Claude Favre de Vaugelas was a Savoyard-born courtier who found his true calling not in politics, but in the precise arrangement of words. Living amidst the glittering circles of 17th-century French aristocracy, he became an obsessive observer of how the most esteemed figures spoke. For nearly four decades, he dedicated himself to a singular project: documenting and prescribing the 'proper' usage of French as practiced by the royal court and the best contemporary authors. His 1647 work, 'Remarks on the French Language,' was not a dry textbook but a collection of observations and rulings that became the definitive guide for anyone wishing to sound polished and correct. His influence was immediate and profound, helping to freeze a moment of elite speech into a permanent national standard, shaping French literature and official communication for centuries.
