The Greek alphabet is the alphabet used in the Greek language, and it is also widely used in mathematics, physics, biology, chemistry, astronomy, and other subjects. The Greek alphabet is similar to the Latin and Cyrillic alphabets and is a diaphonemic script.

Letter Development:

The Greek alphabet was the first writing system in the world to have letters that represented vowel phonemes. The Cyrillic and Georgian alphabets used in Russian, Ukrainian, etc., were developed from the Greek alphabet. Some of the Greek words related to the Greek alphabet have found their way into many languages, such as delta, which comes from the Greek δ because the δ is shaped like a triangle.

The Greek alphabet is derived from the Phoenician alphabet, which has only consonants and is written from right to left, and the Greek language has developed vowels, to which the Greeks added vowel letters.

Because the writing instrument of the Greeks was a wax tablet, sometimes the previous line was written from right to left and then then written from left to right, which became the so-called "plough" type of writing, and then gradually evolved into all left-to-right writing. The direction of the letters is also reversed. The Romans introduced the Greek alphabet, which was slightly changed to the Latin alphabet, which became popular in the world of skating.
