     The English language started about 1,500 years ago in England. Three groups of people came to the

country.  They were the Angles,  the Saxons,  and the Jutes. These three groups brought their languages

with them to England-After some time, the three languages became one new-language-English. The

name  "English" comes from the Angles. They lived in most of England. "England" means "Angle Land" or "Country of the Angles".

     The language that we speak today－Modern English－is not the same as the English that people used many years ago, including Old English(before 1150)and Middle English(up till 1500).That language-Old

English-sounds different, and it has some different rules of grammar. There were only a few thousand

words in Old English. But Modern English does come from Old English, and it is still like it in many

important ways.
