English letters are derived from Latin letters, Latin letters are derived from Greek letters, and Greek letters evolved from Phoenician letters.

Phoenicia is an ancient civilization on the east coast of the Mediterranean, and its geographical position is roughly equivalent to the coastal areas of Lebanon and Syria today. "Phoenicia" is the Greek name of this area, which means "the country of purple" and is named after its rich purple dyes. The Romans called it "Punic".

In the early 20th century BC, Phoenicia had some small slave cities, but it never formed a unified country. In ancient times, Phoenicia was famous for its industry, commerce and navigation. By 10 century BC, its activities had reached Cyprus, Sicily, Sardinia, France, Spain and North Africa, and many colonies had been established. After the 8th century BC, Assyria, New Babylon and other countries invaded Phoenicia. In the 6th century BC, Phoenicia was finally annexed by the Persian Empire.

About13rd century BC, Phoenicians created the first alphabet in human history, with ***22 letters (no vowels). This is the great contribution of Phoenicians to human culture. The Phoenician alphabet is the beginning of the world alphabet. In the west, it derived from ancient Greek letters and developed into Latin letters and Slavic letters. Greek letters and Latin letters are the basis of letters in all western countries.
