Alphabet

An alphabet is a set of letters used to write down the sounds of a language. Each letter stands for a sound, or sometimes a small group of sounds. By putting the letters together in different orders, people can write any word in the language. The English alphabet has 26 letters, from A to Z.

Alphabets are not the only way to write. Some languages use different systems. Chinese, for example, uses thousands of characters, where each one stands for a whole word or idea. Ancient Egyptians used pictures called hieroglyphics. An alphabet is special because it uses only a small number of symbols. Once you learn the letters, you can read and write almost any word.

The first true alphabet was invented around 3,800 years ago by people called the Phoenicians. They lived along the coast of what is now Lebanon and Syria. Before their invention, writing systems often had hundreds of symbols, which took years to learn. The Phoenician alphabet had only 22 letters. It was so easy to learn that it spread quickly through trade. Sailors carried it to faraway ports.

The Greeks borrowed the Phoenician alphabet and added something important: vowels. Vowels are letters like A, E, I, O, and U. The Romans then borrowed the Greek alphabet and changed it again. The Roman version, called the Latin alphabet, is the one used to write English today. It is also used for Spanish, French, German, Vietnamese, and many other languages.

Many alphabets are used around the world. Russian and Ukrainian are written with the Cyrillic alphabet, which has 33 letters. Arabic is written with 28 letters that flow right to left across the page. Hebrew, Greek, Korean, Thai, and Armenian all have their own alphabets. The Korean alphabet, called Hangul, was invented in the 1440s by King Sejong. He wanted writing to be easy for everyone to learn, not just scholars.

Alphabetical order is itself a useful invention. Dictionaries, phone books, libraries, and class rosters all line things up by the order of the letters. This makes finding a word or name much faster than searching one by one.

Letters look like simple shapes, but they carry every story, song, and science book ever written down. The 26 letters in this entry are the same 26 used in every English book in your school library.
