85 percent of the 30,000 Anglo-Saxon words died out under the influence of the Danes and Normans. That means that only about 4,500 Old English words survived--about 1 percent of the total number of words in the Oxford English Dictionary. And yet those surviving words are among the most fundamental words in English: man, wife, child, brother, sister, live, fight, love, drink, sleep, eat, house, and so on.
