Alphabets are a standardized set of letters, each of which represents a sound that is spoken out loud. The alphabets, unlike the hieroglyphs of the ancient Egyptians or the picture symbols of the Mayans, are not based on a picture system. The English alphabet has 26 letters; out of which six are vowels. The Arabic alphabet has more letters and is also read in a different way: from right to left. In the earliest alphabet that we know, there were letters only for consonants. Starting from 1000 B.C., the Greeks introduced letters for vowels. The word ‘alphabet’ is derived from the first two letters of the Greek alphabet: alpha and beta.
