     If you ask people to name the one person who had the greatest effect on the English language, you will

get answers like "Shakespeare," "Samuel Johnson," and "Webster," but none of these men had any effect at

all compared to a man who didn't even speak English -William the Conqueror.

     Before 1066,in the land we now call Great Britain lived peoples belonging to two major language groups.

In the west-central region lived the Welsh, who spoke a Celtic language,and in the north lived the Scots,

whose language, though not the same as Welsh, was also Celtic.In the rest of the country lived the Saxons,

actually a mixture of Anglos, Saxons,and other Germanic and Nordic people,who spoke what we now call

Anglo-Saxon (or Old English ), a Germanic language. If this state of affairs had lasted, English today would

be close to German.

     But this state of affairs did not last. In 1066 the Normans led by William defeated the Saxons and began

their rule over England.For about a century,French became the official language of England while Old English

became the language of peasants. As a result,English words of politics and the law come from French rather

than German. In some cases,modern English even shows a distinction (区别) between upper-class French

and lower-class Anglo-Saxon in its words.We even have different words for some foods, meat in particular,

depending on whether it is still out in the fields or at home ready to be cooked,which shows the fact that the

Saxon peasants were doing the farming, while the upper-class Normans were doing most of the eating.

     When Americans visit Europe for the first time, they usually find Germany more "foreign" than France

because the German they see on signs and advertisements seems much more different from English than

French does.Few realize that the English language is actually Germanic in its beginning and that the French

influences are all the result of one man's ambition.
