These letters are arranged in a specific order to form a system that allows us to write down the language using a combination of different letters. In this system, some letters represent sounds that are produced using the throat, lips, and tongue, while others represent sounds that are produced using the lungs and windpipe.The English alphabet has both uppercase and lowercase letters.
