Although English is not as old as Chinese, it is spoken by many people around the world every day. English speakers are always creating new words, and we should be able to know where most words come from.

Sometimes, however, no one may know really where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham( 火腿 )? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburger. They didn’t speak good English, but they ate good food. When some Americans saw them eating round pieces of beef, they asked the Germans what it was. The Germans did not understand the question and answered. “We came from Hamburger.” One of these Americans owned a restaurant, and had an idea. He cooked some round pieces of beef like what the men from Hamburger ate. Then he put them between two pieces of bread and started selling them. Today “ hamburgers” are sold in many countries around the world.

Whether this story is true or not, it certainly is interesting. Knowing why any word has a certain meaning is interesting, too. The reason may be found in any large English dictionary.
