Anglo-French

The Battle of Hastings in October 1066 did not merely change England's king — it transplanted an entire language onto a Germanic-speaking island. William the Conqueror and his Norman lords brought a dialect of Old French that had itself evolved from Latin, filtered through a century of Scandinavian settlement in the duchy of Normandy. This was not the French of Paris or the Loire. It carried distinct sounds that continental French had already shed, a vocabulary shaped by Viking contact, and an accent that would grow stranger still as it spent generations on English soil far from its source.

For roughly two centuries after the Conquest, Anglo-French operated as the prestige language of England's court, church, and aristocracy. Poets composed romances in it — the earliest known Arthurian tales reached written form in Anglo-French, through writers like Wace and Marie de France. Lawyers argued in it; royal charters were drafted in it. It held a position parallel to Latin: not the speech of the common people, but the medium through which power expressed itself. Meanwhile, beneath it, Old English was transforming into Middle English, absorbing thousands of Anglo-French words into its bones as it went.

The fourteenth century broke the language's social grip. The Black Death of 1348 killed perhaps a third of England's population and scrambled the hierarchies that had kept Anglo-French aloft. The Hundred Years' War made France an enemy rather than a cultural model. The Statute of Pleading in 1362 required English to be used in law courts. By the time Chaucer wrote the Canterbury Tales, Anglo-French was already retreating from living speech; Chaucer mocked the provincial Anglo-French of his Prioress, who spoke it 'after the scole of Stratford atte Bowe' rather than the French of Paris.

What survived was Law French: a frozen, increasingly artificial dialect used in English legal proceedings well into the seventeenth century. Judges who had never spoken French as a mother tongue continued arguing cases in this fossil tongue, sometimes producing prose that mixed French grammar with English content in ways that became genuinely comic. Parliament formally abolished Law French in 1731. But its traces never left: verdict, plaintiff, defendant, larceny, perjury, covenant, felony, tort, mortgage, easement — these Anglo-French legal fossils still structure English law, and through English common law, the legal vocabulary of much of the world.
