The Greek Alphabet is a writing system that has been used since the 8th century BCE. It consists of 24 letters, each with an uppercase and lowercase form. The alphabet is the basis for many modern scripts, including Latin and Cyrillic, and is essential for the study of Ancient Greek literature and philosophy. Each letter in the Greek Alphabet has a corresponding sound, and some letters represent both consonants and vowels. Notable letters include Alpha, Beta, Gamma, and Omega. The alphabet is still used today in Greece and for various scientific and mathematical symbols worldwide.
