An alphabet is a set of letters or symbols used to represent the basic sounds of a language. Each letter corresponds to a specific sound, allowing people to read and write words. The most widely used alphabet in the world is the Latin alphabet, which consists of 26 letters, ranging from A to Z. Different languages may have their own unique alphabets. For example, the Cyrillic alphabet is used in languages like Russian, while the Arabic alphabet is used in Arabic-speaking countries. Alphabets are essential for communication, literacy, and preserving cultural heritage.
