Middle English

In 1066 William the Conqueror, the Duke of Normandy (part of modern France), invaded and conquered England. The new conquerors (called the Normans) brought with them a kind of French, which became the language of the Royal Court, and the ruling and business classes. For a period there was a kind of linguistic class division, where the lower classes spoke English and the upper classes spoke French. In the 14th century English became dominant in Britain again, but with many French words added. This language is called Middle English. It was the language of the great poet Chaucer (c1340-1400), but it would still be difficult for native English speakers to understand. French became the language of the Norman aristocracy and added more vocabulary to English. More pairs of similar words arose.

Because the English underclass cooked for the Norman upper class, the words for most domestic animals are English (ox, cow, calf, sheep, swine, deer) while the words for the meats derived from them are French (beef, veal, mutton, pork, bacon, venison).
The Germanic form of plurals (house, housen; shoe, shoen) was eventually displaced by the French method of making plurals: adding an s (house, houses; shoe, shoes). Only a few words have retained their Germanic plurals: men, oxen, feet, teeth, children.
French also affected spelling so that the cw sound came to be written as qu (eg. cween became queen).
It wasn't till the 14th Century that English became dominant in Britain again. In 1399, King Henry IV became the first king of England since the Norman Conquest whose mother tongue was English. By the end of the 14th Century, the dialect of London had emerged as the standard dialect of what we now call Middle English. Chaucer wrote in this language.
