There are 26 letters in the English alphabet, ranging from A to Z. This alphabet serves as the foundation for written English and includes both uppercase and lowercase forms of each letter. The English alphabet is derived from the Latin alphabet and has been adapted over centuries to fit the phonetic sounds of the language. Each letter represents specific sounds that, when combined, form words enabling communication. The alphabet is a crucial component of literacy and is taught from an early age to facilitate reading and writing skills.
