The development of the English language took a giant step in 1607. Three small British ships c1. the Atlantic Ocean. They began to call areas of their new land by words borrowed from the native people. For example, many of the great r2. in the United States are taken from American Indian words. The Mississippi, the Tennessee, the Missouri are examples. This borrowing or adding of foreign words to English was a w3.of expanding（扩大）the language. The names of three days of the week are good examples of this. The people from Northern Europe honored three gods with a special day each week. The gods were Odin, Thor and Freya. Odin’s-day became Wednesday in English, Thor’s-day became T4. and Freya’s-day became Friday.

Experts cannot explain many English words. For h5. of years, a dog was called a “hound.” The word is still u6. but not as commonly as the word “dog.” English speakers just started using it. Other words whose origins are unknown i7.“fun,” “bad,” and “big.”

English speakers also continue to invent n8. words by linking old words together. A good example is the words “motor” and “hotel.” Many years ago

s9. linked them together into the word “motel.” A motel is a small hotel near a road where people travelling in cars can stay for the night.

Other words come from the f10. letters of names of groups or devices. For example, the North Atlantic Treaty Organization is usually called NATO.
