Extended information:
1. English began in the Anglo-Saxon era in the 6th century AD. It was Roman Catholic missionaries who were responsible for translating the spoken language of the natives into writing.
The problem they face is that there are more than 40 different phonemes in English (Old English), but they only have 23 Roman letters in their hands, and these 23 letters cannot correspond to each other. So they tried many different methods, slowly coming up with 27 letters (which later evolved into the 26 letters in modern English) and some spelling rules.
2. The Latin alphabet (Roman alphabet) is the most widely spread alphabet system in the world, originating from the Greek alphabet.
The Latin alphabet, Arabic alphabet and Cyrillic alphabet (Cyrillic alphabet) are known as the three major alphabet systems in the world. Most Western countries and regions use the Latin alphabet. The Latin alphabet is also used in the Chinese Pinyin system, and the Zhuang and other ethnic minorities also use the Latin alphabet in the creation and reform of Chinese characters.
3. The Latin alphabet developed indirectly from the Greek alphabet from the 7th to 6th centuries BC and became Roman writing.
