Source of letters:
Alphabetic characters can be traced back to Phoenician letters, such as Hebrew letters, Arabic letters, Greek letters, Latin letters, Sanskrit letters, Manchu letters and so on.
Phoenician letters can be said to be the origin of pinyin, and also the origin of many writing systems except Chinese and similar languages (such as proverbs and pseudonyms).
At first, each letter in the Latin alphabet was an abstract symbol, depicting the shape of an animal or an object. Unlike Chinese characters, these symbols bear little resemblance to the shapes of objects originally described. No one is sure what these hieroglyphs originally represented. Our explanation can only be an informed guess made by scholars based on historical materials.
It is generally believed that Greek letters are the ancestors of all western letters, including Latin letters. In fact, the Greek alphabet is borrowed from the Phoenician alphabet.
About 3000 years ago, in the Phoenician alphabet, the letter A was pronounced aleph, which looked like the letter V, and there was a bar in the middle to represent the cow's head or horn. Later the Greeks wrote backwards. For ancient Phoenicians, cattle meant wealth and were indispensable for food, clothing and farming.
