Influence of French on English

The influence of French on English pertains mainly to its lexicon, including orthography, and to some extent pronunciation. Most of the French vocabulary in English entered the language after the Norman Conquest in 1066. Old French, specifically the Old Norman dialect, became the language of the new Anglo-Norman court, the government, and the elites. That period lasted for several centuries through the Hundred Years' War (1337–1453). However, English has continued to be influenced by French. Estimates of the proportion of English vocabulary that originates from French range from one third to two thirds.^[clarify]

In the early 11th century, Old English was not a single unified language but a dialect continuum that stretched from the southern English coast to the Forth estuary. However, a literary standard had emerged that was based around the West Saxon dialect spoken in the area centred on Winchester, the capital of Wessex. Also spoken in the territory ruled by the Anglo-Saxons were the Celtic languages of Old Cornish, Old Welsh, and Cumbric, mainly in peripheral regions in which settlement by the Anglo-Saxons had been fairly minor, and Old Norse across a wide swath of territory in the North and the East of England.

During Harold Godwinson's visit to Normandy in 1064, he was captured by Guy I, Count of Ponthieu and handed over to William, who used Harold to subdue Conan, the count of Brittany. A condition of Harold's release was that he promised to become William's vassal and prepare the way for Norman rule of England. Thus, William felt wronged when Harold was crowned Harold II of England in January 1066.

William II of Normandy landed at Hastings, Sussex, on 29 September 1066. He deployed his men in the nearby area while he waited for King Harold Godwinson's troops. On 14 October, exhausted by previous clashes with Scandinavians in the north and the long journey to Hastings, the English army quickly lost the battle and became disorganised after Harold was killed. After the defeat of the English, William claimed the throne as King of England on 25 December 1066. He was crowned William I of England and came to be known as William the Conqueror, Guillaume le Conquérant in French.

William's followers became a new Norman ruling class and imposed their language on the upper echelons of society. Anglo-Saxon dialects were supplanted by Norman in the royal court and aristocratic circles, the justice system, and the Church. Influential Norman settlers used their native language in daily life. More modest rural and urban areas of society continued to speak varieties of Anglo-Saxon (or proto-English).

The Norman Conquest marked the beginning of a long period of interaction between England and France. Noble English families, most of them of Norman origin, taught their children French or sent them to study in France. The early Norman kings spent more time in Normandy than in England. Royal marriages encouraged the expansion of the French language in England. From Henry II Plantagenet and Eleanor of Aquitaine in the early 12th century to Henry VI and Margaret of Anjou in the 15th century, many English kings married French princesses, which kept French as the language of the English court for several centuries, and strengthened its use in England overall.

Throughout the late 11th and 12th centuries, the Norman nobility ruled over both England and Normandy. In 1204, Normandy was lost to France and so the aristocracy began to associate more with an English identity. Anti-French sentiment in England began to grow after Henry III invited relatives of his wife, Eleanor of Provence, to settle in England and bestowed lavish favours on them. Written works promoting the use of English in England began to appear around then, such as the Cursor Mundi. Meanwhile, the French spoken in England was stigmatised as a provincial variety by French speakers from the Continent, particularly because the Anglo-Norman language that was spoken by the elites had taken on a syntactical structure that resembled English. Some nobles had simply shifted to English entirely.

In 1328, Charles IV of France died without an heir. Edward III of England and Philip VI of France disputed the French throne, and the Hundred Years' War ensued. The war provoked further negative feelings towards French in England, as it came to be seen as the language of the enemy. English had reasserted itself as a language of government and learning after over 200 years as a language of low prestige. In 1349, English became the language of instruction at the University of Oxford, which had taught in French or Latin.
