The Greek Alphabet
Once they had a written language, the ancient Greeks wrote down a great many things including fables and myths and legends, business letters, diaries, contracts, and records of meetings. These writings helped scholars to discover a great deal about ancient Greek daily life.
The first two letters of the Greek alphabet are alpha and beta. Those letters were combined to make a new word - alphabet.
The letters in the picture above are alpha, beta, gamma, delta.
