French

French developed from the Vulgar Latin spoken in Roman Gaul, shaped further by the Germanic Frankish language of the region's post-Roman conquerors, whose name the country and language both ultimately carry, and emerged as a distinct literary language by the ninth century, with the 842 Oaths of Strasbourg among the earliest surviving texts recognizably French rather than Latin.

French belongs to the Romance branch of Indo-European alongside Spanish, Italian, Portuguese and Romanian, and its own Oil dialect group historically competed with the Occitan Oc dialects of southern France before Parisian French, backed by royal and later republican centralization, became the standardized national language, a process the Academie francaise has formally overseen since 1635. French colonial expansion from the sixteenth century carried the language across parts of North America, the Caribbean, West and Central Africa, and Southeast Asia, and French remains an official language in numerous former colonies and a working language of major international organizations, giving it continued global reach well beyond metropolitan France despite the decline of the French empire itself. Quebec French, developed from seventeenth-century colonial dialects and later relatively isolated from continental developments, diverged enough in vocabulary and pronunciation to sometimes puzzle European French speakers, illustrating how colonial transplantation can produce distinct regional standards much as occurred with Portuguese in Brazil and Spanish across Latin America.

French carries an exceptionally rich body of Catholic theological literature, from medieval scholastic works produced at the University of Paris, long Catholic Europe's leading center of theological training, through Blaise Pascal's Pensees and the writings of major French mystics, and French Protestant Huguenots produced their own substantial French-language biblical and theological literature before their persecution and the 1685 revocation of the Edict of Nantes drove much of that community into exile, carrying French Protestant scholarship into Britain, the Netherlands and Germany. French has also served as a major language of Western esotericism and occultism, since nineteenth-century French writers including Eliphas Levi, whose own coinage and systematization of much modern ceremonial magic and tarot symbolism was highly influential, and the wider French occult revival of the same period produced foundational texts for modern Western esoteric traditions that were subsequently translated into English and other languages, meaning French, alongside English, functions as a major source language for modern occult and esoteric vocabulary rather than only a receiving language translating older material.
