Maybe the word "hello" is used mere often than any other one in the English language. Everyone in the U. S. A. and other countries uses the word, again and again, every day of the week. The American inventor Thomas Edison is believed to be the first person to use "hello" on the telephone soon after the invention of it. At first, people began their words on the telephone with "Are you there" They were not sure the small machine could really carry voices. Edison was a man of few words. He wasted no time. The first time he picked up the telephone, he didn’t ask if anyone was there. He was sure someone was there and only said, "Hello!" From then on, "hello" is often heard when you picked up the telephone. People all over the world use "hello" every day.
