when did french have its greatest impact on english vocabulary
Foreign language influences in English The French contributed legal, military, technological, and political terminology. Their language also contributed common words, such as the names of meats: veal, mutton, beef, pork, and how food was prepared: boil, broil, fry, roast, and stew; as well as words related to the nobility: prince, duke, marquess, viscount, baron, and their feminine equivalents.[6]:254-258 Nearly 40 percent of English words (in an 80,000 word dictionary) may be of French origin.
Anglo-Norman language French was the mother tongue of every English king from William the Conqueror (1066-1087) until Henry IV (1399–1413). Henry IV was the first to take the oath in English, and his son, Henry V (1413–1422), was the first to write in English. By the end of the 15th century, French became the second language of a cultivated elite.[8]
