The Story

When the Franks swept into Roman Gaul in the 5th century, they did not erase Latin — they broke it, in the most productive way possible. The Germanic warriors of the Merovingian and Carolingian dynasties adopted the local Latin tongue but filtered it through Frankish phonology, stripping away case endings, collapsing vowels, and introducing new Germanic vocabulary for war, land, and loyalty. Over two centuries, this pressure transformed Late Latin into something unrecognizable to Cicero but perfectly legible to a 9th-century farmer in the Seine valley. The result was a living language without a name, waiting for the right moment to announce itself.

That moment came on February 14, 842 CE, when Louis the German swore the Oaths of Strasbourg in what scholars now recognize as the first written Old French document. The oath was sworn publicly so that ordinary Frankish soldiers could understand it — a small bureaucratic act that inadvertently created a linguistic monument. From this single text, the language exploded outward into literature: the Song of Roland gave it epic grandeur around 1100 CE; Marie de France gave it lyric intimacy; Chrétien de Troyes gave it the novel. By the 12th century, Old French was the prestige literary language of western Europe, from Sicily to Scotland.

The Norman Conquest of England in 1066 was the language's greatest act of geographic ambition. Duke William's army spoke a dialect of Old French called Norman, and within a generation that dialect became the language of English law, government, church administration, and aristocratic life. For 300 years, England had a ruling class that spoke French and a working class that spoke Old English — and the collision of these two permanently loaded the English vocabulary with French words for justice, beauty, power, and pleasure. Every English speaker who says mortgage, journey, or marshal is quoting Old French without knowing it.

Old French faded as a distinct stage of the language sometime around 1400 CE, giving way to Middle French under the pressure of the Hundred Years' War, the Black Death, and the slow centralization of Parisian authority. But it did not disappear — it dissolved into its descendants. Modern French carries its bones. English carries thousands of its words. The Crusader states of the Levant carried its dialects to Jerusalem and Antioch, where Romance speech echoed in Arabic-speaking markets for two centuries. And every word in this collection that traces through Norman courts or Plantagenet chanceries carries a drop of Old French in its bloodstream.
