Extended information:
1. English began to become a written language, probably in the Anglo-Saxon era in the sixth century AD. At that time, it was the Roman Catholic missionaries who were responsible for recording the spoken language of the local people into writing. The problem they faced was that the English language at that time (i.e. Old English) had more than 40 different phonemes, but they only had 23 Roman letters in their hands, which could not correspond one to one. So they experimented with many different methods, and slowly came up with 27 letters (which later evolved into the 26 letters of modern English) and some spelling rules.
2. The Latin alphabet (Roman alphabet) is currently the most widely circulated alphabet system in the world, derived from the Greek alphabet. The Latin alphabet, Arabic alphabet, and Cyrillic alphabet are known as the three major alphabet systems in the world. Most countries and regions in the West already use the Latin alphabet. China's Chinese Pinyin program has also adopted the Latin alphabet, and some of China's ethnic minorities (such as the Zhuang) have also adopted the Latin alphabet when creating or reforming their texts.
3. The Latin alphabet was indirectly developed from the Greek alphabet around the 7th to 6th centuries BC and became the writing of the ancient Romans. Before the fall of ancient Rome, it contained 23 letters. , including 18 consonant letters B, C, D, F, G, Z, H, K, L, M, N, P, Q, R, S, T, X, Y and 4 vowel letters A, E, I, O, and a V with an uncertain sound value. In the 11th century, J, U, and W were added to form the 26 letters today.
